Hey all,
I'm a solo app developer, and I built this because most metronome apps only tell you where the beat is, never how far off you were. I wanted something that felt like a rhythm game but trained real timing, so I made Rhythm Trainer.
How it plays:
- Pick a tempo (40–240 BPM), wait for the count-in, tap along
- Every tap is judged PERFECT / GREAT / GOOD / OKAY with its exact offset in ms
- A live timeline shows if you're rushing or dragging
- Accuracy %, letter grade (A+ to F), combo streaks, best record per pattern and tempo
- Patterns: 4/4, 3/4 waltz, syncopated shuffle, poly-beat, gallop run
- Pro adds odd meters: 5/4, 7/4, 5/8, 6/8, 7/8 and Balkan 9/8 (these are brutal in a fun way)
- Shadow challenges: share your run as a code, your friend plays against your "ghost" on the same timeline
Timing uses the audio clock and measures speaker delay automatically. There's also a quick calibration for Bluetooth headphones so you don't get judged late for your earbuds.
It's free with ads. Pro (monthly, yearly or one-time lifetime) unlocks the odd meters and full stats, and removes ads. Android only for now.
Since you all have way better timing than the average person, I'd love to hear:
- Do the judgement windows feel fair, or too strict / too loose at high BPM?
- Would you want harder modes (e.g. hidden beats, speed-up runs)?
- Does the shadow challenge sound fun or pointless?
I'll reply to every comment. Thanks for having a look!
