Sidereal Metronome

One-time purchase, no subscription. Motion effects unlock by practice streak, not payment. BPM, beat, and time left on the Lock Screen — your phone stays down.

Sidereal is a metronome built for daily practice — guitar, bass, piano, drums, and any rhythm work in between.

It keeps the essentials where you can reach them: adjust BPM in a moment, set your time signature and accents, watch a beat you can actually read at a glance, and let the practice timer hold your focus. Whether you're breaking a phrase down slowly, drilling fundamentals, or holding one tempo through a full session, it's easier to settle into the groove.

Features: • Direct BPM control with a clear beat display • Time signature, accent, and rhythm pattern editing • Unmistakable visual feedback on every beat • Practice duration and progress at a glance • Background audio, so the click keeps going while you work • iPhone and iPad, portrait and landscape • No account, no ads — open it and play

Sidereal isn't trying to stack up features. It's built for one thing: steadier, more focused practice.
