Poly Metronome vs Beat

Poly Metronome is a precise, modern practice tool for musicians who want more than just a click. Set any time signature, shape odd meters with accent groupings, layer polyrhythms, then save your setups as presets and setlists — or build up speed with practice sessions that track your progress. A clean interface scales from iPhone to iPad, with a live pulse ring that shows every voice and accent at a glance — and stays in sync with the sound on the speaker, headphones, AirPods or AirPlay. FREE FEATURES • Studio-grade timing engine, 1–800 BPM • Any time signature: 1–32 beats per bar, counted in quarter or eighth notes — 5/4, 7/8, 9/8, 12/8 and more • Accents and groupings such as 2+2+3 for odd meters • Two-voice polyrhythms such as 3:2 or 4:7 • Count-in before playback • Tap tempo and manual BPM entry • Vibration and LED flash on the beat (iPhone) • Foot pedal and Bluetooth keyboard control • Siri and Shortcuts: start, stop and set the tempo hands-free • Lock Screen, Dynamic Island and Control Center controls • AirPlay and Bluetooth speakers, with a latency notice • Searchable user guide with live examples • Ad-free, with dark, light or system theme PRO FEATURES — one-time purchase, Family Sharing supported • Up to 5 polyrhythm voices, each with its own sound, color, accents and pattern • 18 sound banks (10 metronome + 8 polyrhythm) • 16 built-in rhythm patterns and a custom pattern editor with real notation — even a different subdivision on every beat • Presets: create, edit and duplicate, with notes such as the key or capo shown on stage • Setlists: songs in order, each with its own tempo, notes and auto-advance on the downbeat — the app reopens on the same song if it closes mid-gig • Practice sessions: Coach mutes bars to test your inner time, Automator ramps the tempo by bars or seconds, and session goals keep you on track • Practice log: day streak, minutes per day and your top-tempo progress • Siri and Spotlight for your presets, practices and setlists • iCloud sync across all your devices Ideal for drummers, guitarists, pianists, singers, dancers and any musician serious about timing.

Core Features Interactive Interval Training Develop sensitivity to pitch relationships by exploring intervals tuned using just intonation. • Hear intervals begin perfectly aligned • Adjust pitch in real time to hear beats appear and disappear • Tune intervals by ear using guided listening exercises • Practice intervals across multiple keys and registers Chord Tuning and Harmonic Awareness Understand how scale degrees shape harmony by exploring chords built from pure tuning relationships. • Major, minor, diminished, and augmented triads • Seventh chords including dominant, major, minor, half-diminished, and fully diminished • Isolate chord tones to hear how each pitch affects resonance • Adjust individual notes to hear chords stabilize or destabilize Challenge Mode Strengthen listening accuracy through progressive ear-training exercises. • Tune intervals by ear with adjustable difficulty levels • Customize time limits and precision targets • Unlock intervals through guided progression • Track improvement and share results with teachers or directors Lab Mode Experiment freely with pitch relationships and harmonic structure. • Build custom intervals, chords, or harmonic textures • Assign independent tuning values to each pitch • Explore consonance, dissonance, and overtone interaction Designed for Real Musical Environments In rehearsals and performances, musicians rarely hear themselves in isolation. Beat-Less Tuning removes ensemble noise and allows you to focus on deliberate listening, helping you build reliable tuning instincts that translate directly into real musical situations. This app is ideal for: • Band and orchestra students • Choir and vocal ensemble singers (especially Straight-Tone singing) • Drum corps and marching musicians • Barbershop and a cappella performers • Music educators and ensemble directors Why Just Intonation? Most modern instruments use equal temperament, which balances pitch across all keys but slightly compromises many intervals. Beat-Less Tuning introduces just intonation, where intervals follow natural harmonic ratios that create clarity, depth, and resonance. The listening skills developed in this app strengthen tuning awareness in any musical tuning system. Built by Musicians and Educators Beat-Less Tuning was created by Grammy Finalist and Recording Academy Music Educator of the Year Jeremy Bradstreet, in collaboration with software developer Noirit Ghosh Choudhuri. Together they combined decades of teaching experience and advanced software design to create a powerful and intuitive listening tool for musicians at every level. Train your ears. Build your sound. Hear music more clearly.
