What's New in Sit to Stand
1.3.1
September 2, 2026
Every screen now uses the same clear design — bigger type, clearer buttons, one obvious action per screen. Settings, test set-up, the test itself, People and the report screens now match the rest of the app. During the test, each sit-to-stand is counted aloud with a gentle buzz — useful when the phone is held to your chest and you can't see the screen. Test set-up is now a single page instead of four steps. New in Settings: rate the app on the App Store. If the test helps you, a rating helps someone else find it.
