A little screen time.
A little rest.
A simple eye-break timer for study and work. Choose your rhythm and let ToneTime remind you to pause.
The current App Store version (2.1) is in Simplified Chinese. English is coming in 2.2.0. The screenshot previews version 2.2.0. Requires iOS 16 or later.

Your own rhythm
Start with 20 minutes and a 20-second break, or adjust both to fit your day.
Fits your schedule
Choose days and hours. Reminders start and stop with your routine.
Simple and private
No account. No ads. Settings stay on your device.
Timers follow elapsed time, including while locked. Screen Time and notification permissions are needed for ongoing reminders. ToneTime supports daily break habits and does not provide medical diagnosis or treatment.
