Then, <a href=\"https:\/\/www.dcrainmaker.com\/2025\/06\/polar-whoop-consumer-competitor-september.html\" target=\"_blank\" rel=\"noopener\">earlier this summer<\/a> they announced it\u2019d be coming to consumers on September 3rd. At the time, it lacked a name, or many details, but, they did commit to it requiring no subscription.<\/p>\n<p>Now, we find ourselves with all the details, albeit, perhaps not the details we wanted.<\/p>\n<p>The new consumer-focused version of the Polar 360 is called the Polar Loop (<a href=\"https:\/\/www.dcrainmaker.com\/2013\/12\/polar-depth-review.html\" target=\"_blank\" rel=\"noopener\">the same name the company used back in 2013 for a related wearable band<\/a>). The new Polar Loop is virtually identical in every way to the existing Polar 360. Same sensor package, same internal hardware, same app, and same features.<\/p>\n<p>In fact, there\u2019s only two minor differences:<\/p>\n<p>1) The Polar Loop has a metal clasp\/shell (with various colors), versus plastic on the Polar 360<br \/>2) Polar slightly expanded the internal battery to get an additional 1-2 days of battery life compared to the Polar 360<\/p>\n<p>That\u2019s both good and bad, as I\u2019d find out. I\u2019ve been using the Polar 360 for a bit now, in preparation for switching over to the Polar Loop. Effectively, the only difference to my daily life would be a different color shell and a few extra days of battery life. Akin to going from a 41mm Apple Watch to a 45mm Titanium Apple Watch. Thus, making my review process faster.<\/p>\n<p>Except, before you jump on the anti-Whoop train, we need to talk about where the differences are. Because they are vast, and very real.<\/p>\n<p><strong>The Tech Details:<\/strong><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-164739\" title=\"IMG_9457.jpeg\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/09\/IMG_9457-1.jpeg\" alt=\"\" width=\"720\" height=\"540\" border=\"0\"  \/><\/p>\n<p>(Above, the Polar 360, which Polar has confirmed is identical to the Polar Loop, except for a slightly bigger battery and non-plastic casing)<\/p>\n<p>First up, there\u2019s some tech bits to talk through.

That said, don\u2019t get too distracted by all the bright colorful names below. I\u2019ll distill what actually matters in a second.<\/p>\n<p>\u2013 Daily: 24\/7 Activity Tracking: Steps, distance, calories, active time<br \/>\u2013 Daily: Activity Benefit<br \/>\u2013 Daily: Inactivity Alerts<br \/>\u2013 Daily: Heart Rate Monitoring: Real-time, average, and Max HR<br \/>\u2013 Daily: \u00a0Continuous HR Tracking throughout day<br \/>\u2013 Daily: Activity Goal: Daily targets<br \/>\u2013 Sleep: Nightly Recharge: Overnight recovery measurement<br \/>\u2013 Sleep: Sleep Plus Stages: Light, Deep, and REM sleep phase tracking<br \/>\u2013 Sleep: SleepWise: Predicts daytime alertness<br \/>\u2013 Sleep: Sleep Gate (optimal bedtime window)<br \/>\u2013 Sleep: HRV Tracking<br \/>\u2013 Sleep: ANS Tracking<br \/>\u2013 Training: Automatic training detection (or manual)<br \/>\u2013 Training: Energy Expenditure: Calories burned per session &amp; throughout day<br \/>\u2013 Training: Training Load Pro<br \/>\u2013 Training: Tracking with Polar Flow app (including GPS details with app)<br \/>\u2013 Training: Fitness Test (with Polar Flow app)<br \/>\u2013 Training: Voice Guidance (with Polar Flow app)<br \/>\u2013 Platform: Full access to Polar Flow (web-desktop\/smartphone)<br \/>\u2013 Platform: API &amp; SDK connectivity included (e.g. to Strava, Komoot, etc\u2026)<\/p>\n<p>Now, I do want to circle back to the new Polar Flow platform\/app coming soon, but let\u2019s first talk about how the Polar Loop\u2019s functionality, then talk about the upcoming (but not yet available) Polar Flow revamp.<\/p>\n<p>      <strong>Day to Day Activity &amp; Sleep Metrics:<\/strong><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-164737\" title=\"IMG_9455.jpeg\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/09\/IMG_9455.jpeg\" alt=\"\" width=\"720\" height=\"540\" border=\"0\"  \/><\/p>\n<p>So let\u2019s just work our way through a typical day with the band. Note that in my case I\u2019m using the release candidate firmware and app that\u2019ll go public with the Polar Loop. Thus, while things might change very slightly, don\u2019t expect much to change significantly in the next week or two, given the Polar 360 has already been in the market for nearly a year now.<\/p>\n<p>In any case, waking up you\u2019ll see your sleep metrics within the Polar Flow app. The app is identical to the existing Polar Flow app. You can see my sleep times, sleep phases, HRV metrics, etc\u2026<\/p>\n<p>Now, to Polar\u2019s credit, they willingly admitted the existing Polar Flow app is \u2018not awesome\u2019 (to paraphrase a long presentation section on it). Thus, what you see above is the production iOS app. Soon, an updated Android app will be available with a revamped user interface. That will bring things closer to their goal state next year. Then, later this year the iOS app will get a similar Phase 2 revamp. Here\u2019s a couple of screenshots provided by Polar on what this will look like:<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-164729\" title=\"PolarFlow-Phase2.jpg\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/09\/PolarFlow-Phase2.jpg\" alt=\"PolarFlow Phase2.\" width=\"719\" height=\"406\" border=\"0\"  \/><\/p>\n<p>You\u2019ll notice things like HRV status are now brought forward much more prominently, versus being buried deep in other metrics. It definitely looks a lot better than before, though, does fall a bit short of the type of revamp that I think is really needed to compete with Whoop here (a company that I disagree with on lots of things, but I think their app is excellent at surfacing information in easy to understand ways).<\/p>\n<p>As you can see above, that looks fantastic. So much better than before. But that\u2019s really only the start.<\/p>\n<p data-test=\"6\/4\" id=\"one-important-note-everything-from-here-on-out-is-concept-art-its-not-realyet-and-thus-probably-will-be-different-in-its-final-form\"><strong>(One important note: Everything from here on out is concept art. It\u2019s not real\u2026yet. And thus, probably will be different in it\u2019s final form.)<\/strong><\/p>\n<p>After that, Polar\u2019s going to move into Phase 3, and that looks even better. Finally!<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-164730\" title=\"Polar-Flow-Phase3.jpg\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/09\/Polar-Flow-Phase3.jpg\" alt=\"Polar Flow Phase3.\" width=\"719\" height=\"391\" border=\"0\"  \/><\/p>\n<p>Here you can see the onboarding process:<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-164731\" title=\"PolarFlowVNext-1.jpg\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/09\/PolarFlowVNext-1.jpg\" alt=\"PolarFlowVNext 1.\" width=\"719\" height=\"418\" border=\"0\"  \/><\/p>\n<p>Then we\u2019ve got the ability to customize the tiles that you want to see:<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-164732\" title=\"PolarFlowVNext-2.jpg\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/09\/PolarFlowVNext-2.jpg\" alt=\"PolarFlowVNext 2.\" width=\"718\" height=\"437\" border=\"0\"  \/><\/p>\n<p>And here\u2019s a bit more on down-the-road bits:<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-164733\" title=\"PolarFlowVNext-3.jpg\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/09\/PolarFlowVNext-3.jpg\" alt=\"PolarFlowVNext 3.\" width=\"719\" height=\"428\" border=\"0\"  \/><\/p>\n<p>Overall, I really like the looks of this. Though, when exactly we\u2019ll see it remains to be seen.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-164734\" title=\"PolarFlowVNext-4.jpg\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/09\/PolarFlowVNext-4.jpg\" alt=\"PolarFlowVNext 4.\" width=\"719\" height=\"409\" border=\"0\"  \/><\/p>\n<p>In any case, moving along back to the Polar Loop. Note that there is no wakeup alarm functionality on the Polar device. That\u2019s still in the realm of your other devices (phone, other watch, Cuckoo clock, etc\u2026).<\/p>\n<p>Now, throughout the day it\u2019ll track your steps\/activity, just like other Polar devices. You won\u2019t see flights of stairs though, as it has no altimeter in there. This is an area where Polar\u2019s UI is quite far behind virtually all their competitors (in talking about basic activity tracking). For example, I can\u2019t tap\/click on any of those metrics at the bottom to see those charted over longer periods of time, etc\u2026<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-164724\" title=\"IMG_0831.PNG\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/09\/IMG_0831.png\" alt=\"\" width=\"235\" height=\"511\" border=\"0\"  \/> <img loading=\"lazy\" decoding=\"async\" class=\"wp-image-164725\" title=\"IMG_0848.PNG\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/09\/IMG_0848.png\" alt=\"\" width=\"235\" height=\"511\" border=\"0\"  \/><\/p>\n<p>Ok, with those basics out of the way, let\u2019s step it up.<\/p>\n<p><strong>Training &amp; Workouts:<\/strong><\/p>\n<p>Next, let\u2019s go do a workout. The Polar Loop\/360 will automatically detect the act of a workout, though, will not detect what type of workout it is. Thus, all workouts detected are simply classified as \u2018Other Indoor\u2019. This is a massive difference to Whoop, which will detect whether it\u2019s road cycling, indoor cycling, mountain biking, and a gazillion other workout types.<\/p>\n<p>In Polar\u2019s case, there\u2019s a (very important) slide that lets you tweak the sensitivity of the workout detection algorithm. You can see it below:<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-164723\" title=\"IMG_0833.PNG\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/09\/IMG_0833.png\" alt=\"\" width=\"235\" height=\"511\" border=\"0\"  \/> <img loading=\"lazy\" decoding=\"async\" class=\"wp-image-164721\" title=\"IMG_0834.PNG\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/09\/IMG_0834.png\" alt=\"\" width=\"235\" height=\"511\" border=\"0\"  \/><\/p>\n<p>The idea behind this is to find balance for when it triggers to start recording a workout in the background. Polar says the thresholds are roughly as follows:<\/p>\n<blockquote>\n<p><strong>High:<\/strong> Training is only recorded when you\u2019re doing vigorous activities, such as running, skiing, or other high-intensity sports.<\/p>\n<p><strong>Medium (default):<\/strong> Activities like a brisk walk or light jog are enough to start recording.<\/p>\n<p><strong>Low:<\/strong> Even light activity, such as leisurely walking or doing household chores, can trigger training recording.<\/p>\n<\/blockquote>\n<p>But wait, there\u2019s more! I do appreciate how often Polar comes back with tons of details, as is the case here. Here\u2019s even more details on how\/when\/what\/why it triggers:<\/p>\n<blockquote>\n<p>For a training session to be automatically recorded, it must meet certain duration and intensity requirements.<\/p>\n<p>\u00b7 Duration: The activity must last at least 10 minutes to be saved as a workout.<\/p>\n<p>\u00b7 Intensity: Your heart rate and activity need to reach and maintain certain levels:<\/p>\n<p>To start tracking, your heart rate must exceed 50% of your Heart Rate Reserve (HRR) \u2014 the difference between your maximum and resting heart rates. This typically means the activity should fall within Heart Rate Zone 1 or higher.<\/p>\n<p>To keep tracking, your heart rate must stay above 25% of your HRR, or alternatively, the device must detect continuous high physical activity via the accelerometer.<\/p>\n<p>Your activity level must reach 6.0 METs (a measure of exercise intensity) or higher to start. Tracking stops when activity drops to 3.0 METs or below, unless your heart rate remains high enough despite low movement. This can happen, for example, when cycling, where your wrist stays almost still while holding the handlebars.<\/p>\n<p data-test=\"7\/4\" id=\"met-examples\"><strong>MET examples:\u00a0<\/strong><\/p>\n<p>\u00b7 MET: Sitting quietly<\/p>\n<p>\u00b7 2.5 METs: Walking slowly<\/p>\n<p>\u00b7 5.0 METs: Walking briskly<\/p>\n<p>\u00b7 9.8 METs: Running at a 10-minute mile pace (6:00 min\/km).<\/p>\n<p>\u00b7 11.0 METs: Running at 7.0 mph (11 km\/h, or about 5:25 min\/km)<\/p>\n<p>Note: These intensity values apply to the Medium training intensity setting, which is the default. The thresholds are higher for the High setting and lower for the Low setting.<\/p>\n<\/blockquote>\n<p>Now, as much as I love detail, I also love things to \u2018just effing work\u2019. And honestly, this just doesn\u2019t work.<\/p>\n<p>In all my testing thus far at different levels, I have yet to capture a single workout correctly. They are either missing entirely, broken into vast chunks with missing pieces, started late, or ending 30-45 minutes after the workout complete. For example, it didn\u2019t track my 30-minute trainer ride at all today. It wasn\u2019t super long, as I was running late to catch a flight \u2013 but, nonetheless, it was a workout.<\/p>\n<p>Still, I\u2019ll pause that line of thought to say that Polar says they may have delivered an incorrect firmware to my Polar 360, which may be resulting in my issues. They say that I should wait until the final firmware next week (Sept 10th) to re-test things.<\/p>\n<p>And look, I\u2019ll obviously do that. But at the same time honestly, I remain pretty skeptical about this line of reasoning. With the company saying they\u2019re going to ship in a mere 7 days, I\u2019m kinda surprised that any near-final firmware would be meaningfully different than what comes next week. Activity detection is clearly happening, just not at all very well. In the current state, it\u2019s unusable.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-164718\" title=\"IMG_0836.PNG\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/09\/IMG_0836.png\" alt=\"\" width=\"235\" height=\"511\" border=\"0\"  \/> <img loading=\"lazy\" decoding=\"async\" class=\"wp-image-164720\" title=\"IMG_0838.PNG\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/09\/IMG_0838.png\" alt=\"\" width=\"235\" height=\"511\" border=\"0\"  \/><\/p>\n<p>But, let\u2019s set this all aside for a second and pretend it nails the start\/times exactly correct. The next challenge is there\u2019s no way to modify any of these sessions. So if I wanted to edit\/truncate an automatically detected training\/workout, I can\u2019t do that. Inversely, if it misses the first 15-20 minutes of a session (as it does), I can\u2019t simply extend it forward. And if it misses entire sessions (like all of my panel sessions), I can\u2019t do that either.<\/p>\n<p>This is a *massive* difference to Whoop, which not only gets virtually every single workout I have correct down to the minute, but also lets me edit them (longer\/shorter\/new) in the unlikely event it\u2019s incorrect.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-164709\" title=\"IMG_6034.PNG\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/09\/IMG_6034.png\" alt=\"\" width=\"235\" height=\"509\" border=\"0\"  \/> <img loading=\"lazy\" decoding=\"async\" class=\"wp-image-164710\" title=\"IMG_6035.PNG\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/09\/IMG_6035.png\" alt=\"\" width=\"235\" height=\"509\" border=\"0\"  \/> <img loading=\"lazy\" decoding=\"async\" class=\"wp-image-164708\" title=\"IMG_6036.PNG\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/09\/IMG_6036.png\" alt=\"\" width=\"235\" height=\"509\" border=\"0\"  \/><\/p>\n<p>Further, in Whoop\u2019s case, it doesn\u2019t actually matter if it\u2019s categorized as a \u2018workout\u2019 or not. It just looks at your heart rate throughout the day and calculates load based on that. Whereas Polar only calculates training load if the workout is detected\/manually started as load. Thus, for today\u2019s workout where detection didn\u2019t happen, it sees no load.<\/p>\n<p>I can\u2019t overstate how much of a difference this is. It\u2019s literally like looking at a Boeing jetliner, and a one-person glider (no engine), and saying they\u2019re the same. Yes, they are both airplanes, but that\u2019s kinda where it ends. Again, to be clear \u2013 I\u2019m absolutely going to give Polar their chance there, but knowing how it\u2019s supposed to work, it\u2019s already operating at a huge disadvantage to Whoop (even if it works perfectly as Polar plans).<\/p>\n<p>In any event, setting that aside or the moment, here\u2019s the details you get about said workout once completed. Because it doesn\u2019t have GPS in it, you won\u2019t get that data by default.<\/p>\n<p>You can however use the Polar Flow app to create a GPS workout, and then use the sensor from the Polar Loop\/360\u2019s heart rate sensor. In this scenario, you get exact control over the activity duration (start\/stop times), as well as full GPS tracks that sync to platforms like Strava, TrainingPeaks, and others:<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-164711\" title=\"IMG_0841.PNG\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/09\/IMG_0841.png\" alt=\"\" width=\"235\" height=\"511\" border=\"0\"  \/> <img loading=\"lazy\" decoding=\"async\" class=\"wp-image-164713\" title=\"IMG_0840.PNG\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/09\/IMG_0840.png\" alt=\"\" width=\"235\" height=\"511\" border=\"0\"  \/><\/p>\n<p>All of this then feeds into the training load bits that you have, identical to that of Polar\u2019s other wearables, which track training load and recovery recommendations. In the case of below, I had no less than 90 minutes of workouts per day every day that week, and some rides upwards of 2.5+ hours. But only the ones Polar detected will show up here (which\u2026umm\u2026isn\u2019t much).<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-164712\" title=\"IMG_0842.PNG\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/09\/IMG_0842.png\" alt=\"\" width=\"235\" height=\"511\" border=\"0\"  \/> <img loading=\"lazy\" decoding=\"async\" class=\"wp-image-164714\" title=\"IMG_0843.PNG\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/09\/IMG_0843.png\" alt=\"\" width=\"235\" height=\"511\" border=\"0\"  \/> <img loading=\"lazy\" decoding=\"async\" class=\"wp-image-164715\" title=\"IMG_0844.PNG\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/09\/IMG_0844.png\" alt=\"\" width=\"235\" height=\"511\" border=\"0\"  \/><\/p>\n<p>This is where Polar starts to shine. While the current Polar Flow UI is still \u2018not beautiful\u2019, I feel it does deliver more factually useful information in the training load\/recovery realm than Whoop does. Whoop has their completely silly-ass 0-21 strain system for training load. Meaning that the most training load points you can ever attain in a given day is 21. I\u2019ve covered in my past reviews how broken this is (and why every other company, scientific study, sports device, etc doesn\u2019t use this type of tracking).<\/p>\n<p>Whereas Polar uses a very logical (and widely used) system with TRIMP, that allows you to accumulate as much training load as you\u2019d like (just like real-life human physiology). You can see those cardio load scores below:<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-164716\" title=\"IMG_0846.PNG\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/09\/IMG_0846.png\" alt=\"\" width=\"235\" height=\"511\" border=\"0\"  \/> <img loading=\"lazy\" decoding=\"async\" class=\"wp-image-164717\" title=\"IMG_0847.PNG\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/09\/IMG_0847.png\" alt=\"\" width=\"235\" height=\"511\" border=\"0\"  \/><\/p>\n<p>Again, all of this is exactly how it works for all other Polar wearables.<\/p>\n<p>Finally, when it comes to accuracy, all of my testing with the Polar 360 (which Polar has repeatedly emphasized is exactly the same sensor, internals, etc\u2026), shows it spot-on. Well, at least once it detects the exercise is occurring. Here\u2019s an interval run I did (including the Whoop MG too), and all were spot-on.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-164735\" title=\"Ride-AccuracyRun1.png\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/09\/Ride-AccuracyRun1.png\" alt=\"Ride AccuracyRun1.\" width=\"719\" height=\"218\" border=\"0\"  \/><\/p>\n<p>And here\u2019s another snippet from a gravel ride with a bunch of climbing (auto workout detection stopped as I started descending, ending that activity, so I\u2019ve trimmed this to just be the relevant part). Again, Whoop MG in this set too. Note the colors have changed :<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-164736\" title=\"Ride-AccuracyHR1.png\" src=\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/09\/Ride-AccuracyHR1.png\" alt=\"Ride AccuracyHR1.\" width=\"717\" height=\"221\" border=\"0\"  \/><\/p>\n<p>And these results match my other workouts with it as well.<\/p>\n<p><strong>Going Forward:<\/strong><\/p>\n<p>Someone at Polar needs to print off a giant banner (like 3 meters long), and hang it up in the office area of whatever product team owns the Polar Loop. That banner will say one thing on it: \u201cGet Activity Detection Right\u201d.<\/p>\n<p>That includes, but is not limited to, nailing down workouts to the minute, and also getting the workout type correct. These two factors are hugely fundamental to Whoop\u2019s success in their wearable. It makes it truly \u2018wear and forget\u2019, versus the Polar Loop\/360 &amp; AmazFit Helio requiring a fair bit more phone app updating interaction in order to get the same type of data.<\/p>\n<p>Which doesn\u2019t mean that Polar is on the wrong track. There\u2019s a lot of goodness in the Polar ecosystem, from better workout tracing and cardio load tracking, to better recovery metrics, to generally more accurate optical HR sensors, to the fact that it doesn\u2019t have a subscription. That piece alone is huge. But we also can\u2019t let it overshadow the product itself (as some people have on the Amazfit Helio band). Just because it\u2019s positioned as a competitor, doesn\u2019t make it a true replacement. At least, not yet today.<\/p>\n<p>Still, I\u2019m looking forward to testing it out, and seeing where it does fit, and how fast Polar can iterate on it.<\/p>\n<p>With that \u2013 thanks for reading!<\/p>\n<p>FOUND THIS POST USEFUL?
