Could OnePlus finally bring menstrual cycle tracking to the OnePlus Watch 3? (APK teardown)
A new OHealth update finally adds menstrual cycle tracking, and smartwatch support could be on the horizon.


- The latest OHealth v4.31.1 update introduces menstrual health tracking support for OnePlus and OPPO watch users through the companion app.
- The new feature allows users to log and track periods within the app, and we’ve spotted code that indicates smartwatch-based tracking could be coming soon.
- Competing brands like Apple, Samsung, and Google already use temperature sensors alongside logged data to better predict menstrual cycles, but OnePlus currently misses out.
Many people pick up top-tier smartwatches for holistic fitness and health tracking, but many smartwatches outside of the top three (Apple, Samsung, Google) skip a crucial feature: menstrual cycle tracking. OnePlus smartwatches like the much-loved OnePlus Watch 2, Watch 2R and Watch 3 miss out on this feature. Now, there’s new hope that the feature could be coming soon, as the companion OHealth app has finally added support for menstrual health tracking.
