ClockKeepers

ClockKeepers for Android. Run a countdown, interval, stopwatch or clock on your phone and put it on every screen in the room with a link, a QR code, or a five-letter code. Free, no account.

Built for gyms, classes, studios and courts: presets for Tabata, boxing rounds, EMOM, AMRAP and more.

Pro

ClockKeepers Pro is a one-time unlock (8 timers on one board, your own name and logo on the TV, unlimited presets and more). On Android you buy it right inside the app through a secure web checkout then tap Open ClockKeepers and it unlocks on its own (your license key is also emailed). No Google Play account needed.

How to install

1. Download the APK below on your Android phone.
2. Open it. When Android asks, allow installs from your browser or file manager just this once.
3. Tap Install.

Needs Android 7.0 or newer with a current Android System WebView (Chrome 80 or newer). Phones with Google Play keep WebView updated automatically; on phones without it, update WebView from your phone maker's app store.
