Amazfit has teased more features for the upcoming T-Rex 3 Pro smartwatch, which is expected to launch in early September 2025. This premium wearable with an AMOLED display originally leaked at a retailer in the Philippines. Since then, the Amazfit T-Rex 3 Pro was spotted in a Zepp app update.
More recently, Amazfit has been teasing features of an unnamed smartwatch. Based on the teaser images shared in posts on social media (above), it is likely that this wearable is the T-Rex 3 Pro. The first announcement was for the Wild.AI Mini App, helping users sync their training with their hormones. This is already available on models like the Balance 2 (curr. $299.99 at Amazon).
Another advertised Mini App is Intervals.icu, which can be used to analyze data from your running, cycling, swimming and other workouts. The first version of this integration arrived in June 2025, allowing users to sync completed activities and health metrics like step count, resting heart rate and sleep. Since then, support for HRV has been added, and it appears that other things like planned workouts will be added in the future.
An Amazfit and TrainingPeaks integration is said to be “coming soon to the Zepp app”. Users can already sync the Zepp App with TrainingPeaks via the Terra API. This suggests that a direct integration is therefore on the way for this training and fitness tracking app. Finally, Amazfit has teased a Styrd integration. Many of the brand’s smartwatches already support the Stryd Duo running power pod. It remains to be seen how this new integration will benefit users of the Amazfit T-Rex 3 Pro smartwatch.
The T-Rex 3 Pro smartwatch is expected to be officially released on September 5th 2025, priced at £399.90 in the UK. Whether these Mini Apps and integrations could roll out to other Amazfit smartwatches remains to be seen.
