Metronome Pro for iPhone
Programmable subdivision patterns and per-song tempo memory for music students and gigging musicians — for $19.99 once instead of Soundbrenner’s $8-per-month metronome subscription.
Planned Swarmval app. Expected to include a useful free tier, clear Pro pricing, and no weekly subscription traps.

Features
Built around the work people actually need to finish.
Subdivision patterns
Triplets, swing, dotted eighths, custom 16th-note patterns. Hear and see the subdivision so internal time stays locked in.
Per-song tempo memory (setlists)
Save songs with name + tempo + time signature + subdivision. Walk through a setlist on stage with one tap to advance.
Tap tempo
Tap a few times to set BPM. Useful when the band leader counts off a tempo you need to lock to.
Time signature support
Standard 4/4, 3/4, 6/8, 12/8, plus odd meters (5/4, 7/8, 11/8). Accent on beat 1 + custom accent pattern per measure.
Visual + audible cue
Big visual flash on beat 1, dimmer flashes on subdivisions. Headphones + audio out + bone-conduction with AirPods all supported.
No subscription, no ad interruptions
Soundbrenner pushes $8/month for setlists. Pro Metronome is a one-time $4 but ad-loaded on the free path. Metronome Pro from Swarmval ships everything for $19.99 lifetime, no ads.

What is the difference between this and the free Pro Metronome? +
Pro Metronome is $4 one-time but limited; advanced features (setlists, custom subdivisions) require additional in-app purchases that stack to more. Metronome Pro from Swarmval bundles everything at $19.99 lifetime and includes setlists for gigging musicians out of the box.
Can I save tempos for songs in a setlist? +
Yes — the setlist feature is the core differentiator. Add songs with their tempo + time signature + subdivision; advance through on stage with one tap. Setlists save locally.
Will the audio drift over long sessions? +
No — the metronome locks to the audio clock, not the UI clock. Three-hour rehearsal stays sample-accurate.
Does it work with bluetooth headphones? +
Yes, including AirPods, AirPods Pro, and any Bluetooth output. Latency is around 40–80ms depending on the headphones; the visual flash stays sample-accurate.
