Metrognomicon · Coming 2026
A metronome that keeps time, even when it changes.
Build a sequence of tempo segments, each with its own speed and length, and let them play straight through. Hands‑free, end to end.

Most metronomes give you one tempo. This one gives you all the pieces.
Accelerandos, ritardandos, movements that move. Set a passage to run at 120 for sixteen bars, then 138 for the next thirty seconds, then ease back down and let it carry you through.
Each segment by beats or by time. As many as the piece needs. Loop the whole sequence, or play it once and stop.
A wide BPM slider. Tap tempo when you'd rather find the feel than dial it in. Length by minute and second, or by beat.
Manage segments from the play screen. Tap to edit. Hold to reorder. Swipe up to delete.
Choose the click that carries in your room. A count‑off — any sound you pick — plays the last four beats before each tempo change, so the next tempo never sneaks up on you.
Or turn the count‑off off entirely. It's your practice room.
A clean, distraction‑free face. Built for classical players, students drilling difficult passages, and anyone working on a piece that doesn't sit still at a single tempo.
Four count‑off beats, in the sound you choose, before every tempo change.
Tap a tempo, or dial one in precisely.
No servers, no accounts, no analytics. Your sequences live on your device — and only there.
There is, in fact, one. Four, if you're counting. They show up where you'd least expect them—and never where you'd be annoyed by them.
The app runs entirely on your device. It makes no network connections and transmits no data anywhere. No servers, no accounts, no analytics, no advertising, no third‑party tracking of any kind. Your sequences and preferences are saved locally so the app remembers them between sessions — and they leave with the app, if you do.
Send a note. We'll get back to you.
