Subdivide: Metronome & Tuner is an iPhone app launched by developer Tap Five, positioned as a rehearsal engine for musicians, combining a precision metronome, programmable click tracks, audio cue practice, and a chromatic tuner. The app is free to download and offers in-app purchases (Subdivide Pro). It currently has 189 ratings and a 4.8 score on the App Store, is rated 4+, and is available in English.
Purpose The app is aimed at musicians such as soloists, educators, drumlines, and marching bands, helping users practice to the clicks a piece actually requires and share practice tracks with their team.
Key Capabilities
- Precision metronome: Supports subdivisions from quarter notes to septuplets, with per-beat accents; individual subdivisions can be muted to test internal sense of timing; provides Tap Tempo, presets, and a long-tone function cut off by a long press for ensemble endings; supports Live Activities on the Lock Screen and Dynamic Island.
- Full-piece click tracks: Build multi-section tracks, changing tempo, time signature, and subdivision between sections; supports smooth accelerando and ritardando transitions; can import MusicXML and generate a complete track based on the score; provides count-in, looping, and custom start/end boundaries for polishing sections individually; the entire track can be tempo-shifted without changing pitch.
- Marching arts-specific features: Drill Mode organizes tracks by drill page and counts; tracks can be shared with the entire team via QR code, and recipients do not need an account; any track can be exported as audio for rehearsing on other devices.
- Audio cues: Import any recording and place cue points on the waveform; enter on the beat, loop difficult passages, adjust speed; cues can be shared along with the audio to a section.
- Chromatic tuner: Fast pitch detection with cents display; provides a reference tone for tuning by ear.
How to Use Users can control it on iPhone via touch, Bluetooth foot pedals or page turners, Siri Shortcuts, and the Action button. The app supports using the "Toggle met" shortcut while the device is locked, and the shortcut can be assigned to the phone's Action button to quickly start and stop the metronome. Practice statistics and iCloud sync work across devices.
Use Cases Suitable for individual practice, teaching rehearsals, marching band and drumline ensemble practice, and similar scenarios. Users can use the track feature to play a complex piece with multiple tempo changes in one go, and it can also be used for rehearsals by performers such as dancers and color guard members.
