PulseTime
PulseTime turns the time into vibration patterns you can learn by feel, using an Android phone and Wear OS watch.
Download the test builds
Install the companion and watch builds separately while closed testing is being prepared.
Google Play beta: Prefer Play Store updates to sideloading? Join the Coolhand beta group first (I’d really appreciate it). I’ll add this app’s opt-in link here when its Play beta is ready.
Install: Download each APK on its intended device, open the file, and allow installs from this source if Android asks.
Start here
Open the PulseTime companion and run Calibration first, then pair the Wear OS build to begin learning the haptic clock.
Wear OS
The paired watch version is pending Google Play closed testing. This phone download does not install anything on a watch.
