A-Tempo

A-Tempo is a metronome for people who actually play. I built it for my daughter Iris — twelve years old and a violin — when I realised that a metronome with just a "tick" wasn't enough: the moment she worked on her sound, the click vanished underneath the notes.

So I built a metronome that speaks in four different ways — because every musician feels the beat differently.

FOUR WAYS TO FEEL THE BEAT
• Sound — the classic click, crisp and precise.
• Vibration — the phone pulses on every beat. Great for wind instruments, late-night practice, or when the phone sits on the music stand.
• Camera flash — the torch flashes on the beat. Visible even in bright rooms, impossible to ignore when your hands are busy.
• Screen blink — the whole screen pulses softly. A peripheral visual reference, no need to look away from the score.

Use them one at a time or in any combination. There is no universal channel — choose yours.

THE SMALL THINGS THAT MATTER
• Tap Tempo — tap in rhythm and the app finds the BPM.
• Per-channel offset — sound, vibration and flash can arrive with different latencies, so each channel has an adjustable offset to line everything up exactly when you want it.
• Deliberate simplicity — no accounts, no syncing, no manual. A tool to use during practice, not instead of practice.

PRIVACY FIRST
A-Tempo runs entirely on your device. No accounts, no ads, no analytics, no data collection. No connection required.

Built for Iris. Shared with everyone who plays.
