Speed trainer
Set a passage at 60, climb by 4 every eight bars, stop at 120. PULSE holds the plan.
Metronome · Tuner · Drone · Apple Watch
The beat, on your wrist. The same moment, every time.
PULSE is a metronome, chromatic tuner and drone for iPhone. The click, the flash and the tap on your Apple Watch land together — from the first lesson to the stage.

The Watch tap
A beat you feel, so you can stop looking at it.
Each beat arrives as a firm tap on the wrist. Turn the click off in a lesson, on a stage, or in a quiet house — the pulse stays with you, and your eyes stay on the music.
- AlignedClick, flash and tap are scheduled to the same clock, not sent one after another. Nothing arrives late.
- AccentedThe downbeat taps harder. Any beat can be set silent; subdivisions never tap, so the wrist keeps the bar.
- StandaloneStart, stop and change tempo from the Watch. Leave the phone in the case.
Three tools, one instrument
Everything a practice room needs. Nothing it doesn't.
01 · Metronome
A needle that means it.
20–400 BPM, meters from a plain pulse to 7/8, subdivisions from quarters to sixteenths. Tap a tempo, set accents per beat, or save a preset and step back into it. The needle moves with the beat, and the beat only.
Also: silent bars for internalising tempo · gradual speed trainer · four click sounds and a count-in
02 · Tuner
Chromatic, steady, honest to the cent.
A calm cents needle that settles instead of jittering. Reference pitch from 415 to 466 Hz, and transposition for C, B♭, E♭ and F instruments.
Also: pitch is found on the phone and never uploaded · the microphone is on only while the tuner is · the drone follows the same A4
03 · Drone
A note to lean on.
Pick any pitch and hold it. Two voices: Warm, a steady sustained tone, and Piano, which strikes the note again every few seconds — like an A given from the keyboard. Add a perfect fifth and tune the interval, not just the note.
Also: follows A4 from the tuner · step by semitone with − and +
In the lesson
Built for the first lesson as much as the last rehearsal.
Teachers asked for a metronome a student can't argue with. The tap on the wrist is the same beat the teacher hears — and the student feels it before they think about it.
Silent bars
Audible bars, then silent ones. The student learns to hold the tempo without the click.
Large figures
BPM readable from across the room. Stage Arena is a giant beat number; a tap brings the controls back.
Four presets
The tempos you rehearse most, saved with meter, sound, count-in and accents. Tap a slot, it is ready.

Questions
Asked before, answered plainly.
Does the Watch tap really land with the click?
Yes. The phone schedules click, flash and haptic against one clock and sends the Watch a tempo and a start time rather than a stream of taps, so nothing queues up or drifts.
Can I use PULSE without an Apple Watch?
Entirely. The Watch tap is an addition, not a requirement. Everything on the phone works on its own.
Does the Watch work without the phone nearby?
Once a tempo is running, yes — the Watch keeps time on its own, and the Digital Crown changes it. The tuner and the drone need the phone.
What is the difference between the three skins?
Classic is the pendulum with your colour, glass and photo. Stage Arena is a giant beat number for the music stand. Zero is pure black and one thin line on the beat. The beat is brass in all three.
Is there a one-time price?
Yes. Lifetime is a single payment of $34.99 for everything, on every device signed into your Apple Account, with nothing to renew.
What happens if I cancel Pro?
You keep full access until the end of the paid period. After that the app asks you to subscribe again; nothing on the device is deleted.
