PulsePomAndroid
Install PulsePom from Google Play. The Android app has everything, plus the app and website blocker, YouTube University and a timer alarm that rings with your phone locked.
Windows
Install PulsePom from the Microsoft Store. It runs in its own window, with the floating timer on top of your other windows. It has everything except the blocker, which is Android-only.
You can also install it from Edge or Chrome: open pulsepom.io and choose Install in the address bar.
Mac, Chromebook and Linux
Open pulsepom.io in Chrome or Edge and choose Install in the address bar (on a Chromebook, it may be in the menu as Install PulsePom). It then opens in its own window from your apps, and the floating timer works.
You can also just use it in Firefox or Safari, without installing. The floating timer works in Firefox but not in Safari.
iPhone and iPad
There is no App Store app. Open pulsepom.io in Safari, tap Share, then Add to Home Screen. PulsePom then opens from your Home Screen like an app. Blocking isn't available on iPhone or iPad.
One account everywhere
The Timer, Stats and Planner work without an account on each device. Sign in with the same account, free, on every device and your sessions, tasks, habits and stats sync between them.
