Daily
The same rhythms for every player in the world, changing at midnight UTC.
Tap along
with a heartbeat
Arcs close in on the centre of the screen. Tap when they land. Eight cardiac rhythms, from a slow steady beat to atrial fibrillation.
Coming to the App Store
Free on iOS. No ads, no purchases, no tracking.
The audio clock is the only clock. What you see cannot drift from what you hear.
One thumb. That is the whole game.
No tutorial. No setup. A 3, 2, 1 countdown, then arcs from four directions. Tap anywhere in time with each beat.

Arcs close in
Each beat is a ring shrinking toward a centre core. Radius is a pure function of the audio clock, so a dropped frame shifts nothing.
-
Tap when they land
Perfect, good, or miss. Some beats ask for a swipe instead of a tap. Heartbeat haptics sit under the sound if you want them.

Flatline ends the run
Three misses in Daily and Casual. One miss in Competitive. Every hit still pays experience, so a short run is not wasted.
Eight rhythms. Each one already had a difficulty curve.
The medicine shaped these timings. The game just plays them. Pick a row. The trace follows, using the same interval function as the audio engine.
Not a medical device. The names are flavour. Pulse does not measure, diagnose, or advise on anything.
Three modes, two short games, a chart of where you miss.
Casual
Pick a rhythm, or let Auto climb the ladder as you survive. Three misses.
Competitive
The rhythm changes without warning. One miss ends the run. This is the board that ranks.
Reaction and Recall
The heart stops, tap the instant it does. Or hear a phrase and tap it back from memory.
A bad run still moves you forward.
Hits earn experience. Levels unlock colour themes and heartbeat sound kits. Your chart lists the rhythms you are weakest at, weakest first, so you know what to practise.
An account is optional. Guest play is a peer of Apple, Google, or email, not fine print. Leaderboard names are generated and cannot be edited, so the board is never user written text.
The rest of the room
Score, themes, kits, haptics. All of it stays on the device unless you sign in.
Before you ask
Is Pulse a medical app?
No. Pulse is a game. Rhythm names are flavour and difficulty design. It does not measure, diagnose, or advise on anything. If you have concerns about your heart, speak to a doctor.
Do I need an account?
No. Welcome ends with Continue without an account, and the game is complete from there. Sign in only if you want progress on another device, or the leaderboard.
What does it cost?
Nothing. No in-app purchases, no advertising, no tracking. Firebase Analytics is off. No IDFA.
What does Pulse collect?
Nothing if you play as a guest. If you sign in: an account identifier, an email if the provider supplies one, scores, level, and a generated leaderboard name. See the Privacy Policy.
What are Daily, Casual and Competitive?
Daily is the same worldwide seed, reset at midnight UTC. Casual lets you pick a rhythm or climb them. Competitive shuffles without warning and one miss ends it.
What devices does it run on?
iPhone. Built for iOS 27. One thumb, so it is meant to be played in a single hand.
When will it be on the App Store?
It is finished and verified on a real device. A demo video, then submit. This page will grow an App Store button when Apple has a listing.
How do I delete my data?
Settings, Account, Delete account. That removes the account, stored progress, and leaderboard entries. Deleting the app removes what is on the device.
Why those rhythm names?
Each one already had a timing character. Bradycardia is slow. Wenckebach drops a beat. A-Fib has no grid. Using the real names keeps the ladder honest. It is not a lesson about heart conditions.
Can I change my leaderboard name?
No. Names are generated from the account id so the board is never user written text. That keeps the first review out of the user generated content queue.
Coming to the App Store
Eight real cardiac rhythms. One thumb. Free, with nothing to buy and nothing watching you.
