StandUp

StandUp is a local-first iPhone and Apple Watch app for automatic sedentary reminders.

• Apple Watch estimates low-activity sitting time automatically.
• Users can set the sedentary threshold from 15 to 120 minutes.
• Reminders repeat every 10 minutes after the threshold until the user stands or skips.
• Standing or walking for 2 continuous minutes resets the timer.
• In-progress sessions are restored after a local app restart.
• A bounded reminder series is scheduled only within active hours.
• iPhone shows overdue sitting intervals, corrections, and 7/30-day trends.
• Data stays local. There is no account system or server upload.

• Sources/StandUpCore: tested core state machine and analytics.
• Checks/StandUpCoreChecks: executable verification suite for core behavior.
• Apps/Shared: storage, notification, motion, sync, and app model code.
• Apps/iOS: iPhone SwiftUI app.
• Apps/Watch: Apple Watch SwiftUI app.
• project.yml: XcodeGen project definition.
