Lumina Chronos is a focused Pomodoro timer for Android - no account, no analytics, no internet. Just a clean session, on your phone, with a home-screen widget that keeps the timer alive while you work in other apps.

WHY ANOTHER POMODORO TIMER?
Most Pomodoro apps bury the timer in tabs, hide it behind a paywall, or pepper you with ads when you're trying to concentrate. Lumina Chronos does the opposite: it lives quietly on your home screen, sounds the final five seconds so you can finish a thought without staring at your phone, and disappears the moment your session ends.

COLOR-BAND CUES
The progress ring shifts through three colors during a work session so you can read where you are in a glance without parsing numbers:
- Green - early flow, plenty of time.
- Yellow - Slow Down, the wind-down phase.
- Red - Finish, the final stretch.

FINAL-5-SECOND TICKS
A subtle audible tick during the last five seconds of each phase so you can finish a thought without staring at the screen.

HOME-SCREEN WIDGET
Add the widget to your home screen and run the entire timer from there - play, pause, stop, reset, settings, quotes - without ever opening the app. The widget keeps ticking using a foreground service so it stays accurate while you focus on what matters.

PAUSE ON MINIMIZE
Optional: when you minimise the app, the timer pauses automatically. Or keep it running in the background - your choice.

DAILY SPARK
A built-in collection of focus quotes you can flip through between sessions.
