Hi Product Hunt! 👋

I'm Gregg. I taught elementary and middle school band for 13 years (and was an assistant high school marching director), then spent the last 15+ years building apps. Pulsari started with a classroom problem: a metronome loud enough to hear over a band drowned out the music, but without it, students never really learned to feel the beat.

So the beat goes on your wrist. The Apple Watch taps every beat, stronger on the downbeat, while your iPhone on the music stand flashes it in sync. Then I built in the way I taught practice: play the hard passage slowly enough to play it perfectly, then climb the tempo, and slow back down when new mistakes appear.

A few things I'm proud of:

• Snap a photo of your part and Pulsari reads the roadmap (repeats, endings, D.S. al Coda), then plays it on your own page, bar by bar

• More than 90 real drum grooves, so practice feels like playing with a band

• Feel mode for deaf and hard-of-hearing musicians: strong haptics plus a full-screen flash

• Hands-free voice control right in the app: "Metronome, faster"

• On iPhone Duo, it half-folds into its own music stand

Use as much or as little of it as you need. The metronome is free and will never be a subscription; Pro is a one-time purchase, and Coach is optional.

I'd love your honest feedback, especially from musicians and teachers: what's missing, and what gets in the way?
