"Big Clock" is an Android app that shows the time as large as the screen allows and keeps the phone awake while it does. It is meant for a phone propped up nearby, on a lectern during a talk or on a desk, where a glance should be enough.
- White digits on black, sized to fill the screen.
- Turn the phone and the clock follows: one line when the phone lies wide
(
14:05), hours above minutes when it stands tall. - The screen stays on while the clock is showing. Leave the app and the phone sleeps as usual.
- Tap the screen to show or hide seconds. The choice is remembered.
- 12- or 24-hour time follows the phone's own setting.
- The digits move by a few pixels each minute, so a clock left on for hours does not wear the same pixels of the display.
- No permissions, no internet access, no ads, nothing collected.
The clock uses the phone's brightness as it is set; turn it up or down the usual way.
With Obtainium: add this repository's address as an app source and install. Obtainium then offers each new release as an update.
Without it: download the .apk file from the latest
release and open it on the phone. Android asks once
to allow installing from that source.
Needs Android 9 or newer.
GitHub Actions builds it (.github/workflows/build.yml): a test copy on every
push to main, and a signed release on a tag like v1.0, which is what
Obtainium installs. Locally: gradle assembleDebug with JDK 17 and the
Android SDK. What the screen says for a given moment (ClockText.kt) has unit
tests, run on every build.
