Features
Accurate Timer
Timestamp-based logic — never drifts, never lies. Survives backgrounding, phone calls, and lock screens.
Phase Colours
Each phase has its own colour. Know your phase at a glance without reading a single word.
Workout Builder
Create custom workouts with any number of rounds, exercises, and durations. Built-in templates to start immediately.
Background Safe
Local notifications fire for every phase transition even when the screen is locked.
History
Every session saved. Track your work and rest time, rounds completed, and streaks over time.
Audio & Haptics
Distinct beeps and haptic pulses on every phase transition. Train without glancing at your screen.
Phase System
Prepare
Get into position. 3, 5, or 10 second countdown before the first interval.
Work
Give everything. Yellow-green so bright you can't miss it.
Rest
Recover. Cool blue to let your nervous system know it's time to breathe.
Round Rest
Longer recovery between rounds. Skip it for classic Tabata.
Finish
Done. See your stats and do it again.

Overview
Pulse is a HIIT interval timer. It does not collect, transmit, or share any personal data. Everything you create in the app — workouts, history, preferences — stays on your device and is never sent anywhere.
Data We Collect
We collect no personal information. Pulse does not ask for your name, email, location, or any account credentials. There is no sign-up and no login.
Local Storage
Workouts you build and your session history are stored locally on your device using the platform's standard storage. This data never leaves your device. Uninstalling the app removes all stored data.
Notifications
Pulse uses local notifications to signal phase transitions during a workout. These are scheduled and fired entirely on your device. No data is sent to any server to deliver them. You can disable notifications at any time in your device settings.
Third Parties
Pulse contains no third-party SDKs, analytics libraries, advertising networks, or crash reporters. No data is shared with any third party.
Children
Pulse does not collect any data from any user, including children under 13. The app is appropriate for all ages.
Changes to This Policy
If this policy ever changes, the updated version will be published on this page with a new date at the top. Because we collect no data, any changes are unlikely to affect you.
