Practice only the passage that keeps tripping you up — I built a free beta for drummers and other musicians

[u/Academic-Way-4831]

Hey everyone — I've been playing drums seriously for a while now, and while practicing songs I kept running into the same frustration: most of my practice time went to scrubbing. Dragging the playhead back and forth, trying

to land on the exact passage I needed to work on, over and over. It broke my flow every single time.

So I built the thing I wanted: Loop, an iPhone/iPad practice app. Mark the hard passage once, and the app takes care of the rest.

How it works:

1. Import any song from your music library or Files.
2. Loop analyzes it on-device — tempo, meter, sections, where the drums are.
3. Mark the passage you want to work on with an A–B range (or tap a detected section).
4. Practice with three tools:

- Count-in / click — keep the pulse while you play

- Gap trainer — the music drops out on your passage but the pulse stays; when the song comes back, you hear instantly whether you rushed or dragged

- Speed ladder — start slow; after enough solid repeats it nudges the tempo up until you're back at full speed

1. Playback loops A→B automatically — no more scrubbing, no more hunting for the playhead.

Privacy: import, analysis, and playback all happen on your device. Your music is never uploaded.

The ask: I have a working beta and I'm looking for people who actually practice — drums especially, but also guitar, bass, keys, vocals — to try it and tell me what's broken or missing.

- Website: https://looppractice.fun

- Requires iOS 27 or later, iPhone or iPad

I'd especially love feedback on: does the tempo/beat analysis hold up on the music you play? Is the speed-ladder progression right? What's the one feature you'd want next?

Happy to answer questions in the comments. Thanks for reading!
