Android OS is used in a wide range of devices from different manufacturers. Such variety makes it challenging to deliver good quality and error-free app. That's why we release smaller updates more often as far as Android app is concerned.

Changes to the Android app are available publicly several hours after we release them. To use the latest app please upgrade your Swimmo Android app via Google Play Store for stable public releases. You can also subscribe for beta releases.


If you don't have access to the official Google Play Store (i.e. Chinese users), then you can download APK file directly.
