CalmTune is a HarmonyOS Next wearable app that combines the Pomodoro technique with relaxing ambience music. Users can choose from different background sounds (like rain, lofi, or coffee shop) to stay focused during a 25-minute Pomodoro session. When the session ends, the app switches to a break page.
-
Select an ambience (lofi, rain, coffee shop, fireplace, ocean waves, forest, white noise).
-
Start a 25-minute Pomodoro session with the chosen ambience.
-
Track remaining time with a progress bar during both focus and break sessions.
-
Control playback: play, pause, skip, go back to different tracks.
-
Enjoy themed background visuals (e.g., desk, workspace) to enhance focus.
-
Automatically switch to a break page when the session ends.
