Screen Timer — Flip Countdown

Screen Timer is a countdown you can read from across the room — and one that proves it will actually ring.

Set hours, minutes and seconds, hit start, and the digits fill the screen with a 3D flip animation. No sign-in, no account, no ads between you and the clock.

⏰ WHY DIDN'T IT RING? — THE PART EVERY OTHER TIMER SKIPS
The one-star reviews of every timer app say the same thing: "it didn't go off". A silent alarm is not one bug, it's seven, each with a different fix:
• Exact-alarm permission (Android 12 and up)
• Notifications turned off for the app
• The alarm notification channel silenced by hand
• The Alarm volume slider at zero — separate from ringtone and media
• Do Not Disturb blocking it
• Battery optimisation putting the app to sleep
• Lock-screen (full-screen) permission on Android 14 and up
A check screen tests all seven, tells you which one is wrong, and opens the exact settings page for it. Anything it cannot read says "couldn't read this" instead of guessing. Then a real 10-second test alarm proves the whole chain — before you trust it with dinner or a nap.

🕐 THREE DISPLAY STYLES
• Flip — mechanical split-flap digits
• Circle — a ring that empties as time runs out
• Analog — a classic sweeping hand

🔔 RINGS WHEN IT SHOULD
The alarm goes through the system alarm service, so it fires at the right moment even if you leave the app, the phone sleeps, or Android closes the app to free memory. Close it mid-countdown and reopen: the remaining time is still right.

🍅 FOCUS AND INTERVALS
• Pomodoro: work and break lengths, number of rounds, rolls on by itself
• Interval chains: name your own phases, each with its own colour and length — circuit training, tea steeping steps, revision blocks
• A heads-up alert a set number of seconds before time is up
• Home screen widget with the time remaining

📋 SESSION LOG
Every finished and abandoned session, with today's and the last seven days' totals. Kept on this phone, never uploaded; copy it all to text or delete it in one tap, or switch the log off entirely.

🌙 EASY ON THE SCREEN
Left running for an hour on a bedside table or a kitchen shelf, a timer burns into an OLED panel and lights up a dark room. So the screen now dims by itself after a few untouched minutes (touch to wake), the clock nudges a couple of pixels every minute against burn-in, and you can scale the digits up or down. It dims only this app's window, never the system brightness.

🔒 PRIVACY
Your timers and photos stay on your phone. There is no ad network and no account; anonymous usage stats can be switched off in Settings.
The Wi-Fi photo transfer talks only to the other device on your own network.

• Keep the screen awake while counting down

WHY THIS COUNTDOWN TIMER
