## Frequently asked questions
### What is Rhythm Tutor?

A free web app that teaches rhythm with a metronome and 25 clapping patterns across 8 levels. An onset detector hears every clap and scores it against the beat grid in milliseconds, naming each mistake as rushed, dragged, between beats, or missed, with a practical fix. Everything runs on your device. It is a home practice tool, not a music teacher.

### How does it hear my claps?

A tiny onset detector runs inside an AudioWorklet, next to the audio hardware for sample-accurate timing. It listens for the sharp attack of each clap or tap, matches it to the nearest note on the beat grid, and scores the timing error in milliseconds.

### What do rushed and dragged mean?

Rushed means your clap landed before the beat; dragged means it landed after. Each verdict comes with a named hint and a concrete fix: rushed gets "Wait for the click: let it arrive, then clap with it", dragged gets "Get ready earlier: start your clap as the click begins".

### What are the 8 levels?

Level 1 quarter notes, level 2 quarters and rests, level 3 eighth notes, level 4 waltz and 6/8, level 5 off-beats, level 6 sixteenth notes, level 7 syncopation, and level 8 syncopated sixteenths. Passing a pattern unlocks the next level.

### What is quiz mode?

Quiz mode scores patterns you have never practised: quiz patterns are kept separate from practice patterns, with no tips on screen. It is an honest test of whether the timing stuck. Wrong answers always show the named hint, never just a score.

### Can I tap instead of clapping?

Yes. Tap on the table, snap your fingers, or tap the on-screen pad: anything with a sharp attack works. The detector listens for the attack, not the sound's tone.

### Does it work offline?

Yes, after your first visit. The app and the detector are saved on your device, so everything works with no network. The Offline proof panel even lets you simulate a fully offline session.

### Is my audio recorded or uploaded?

No. Microphone audio is measured on your device and immediately discarded. Nothing is recorded, uploaded, or shared. The page security policy blocks connections to every outside server.

### Can I delete my data?

Yes. Open Offline proof on the home page and press Delete all my data, or clear progress from the dashboard. Everything is stored only in your browser, on your device.

### How do the ranks and badges work?

Points climb through four ranks: Steady Starter, Groove Finder, Pocket Player, and Rhythm Master. Badges mark milestones like a perfect take, 16 hits in a row on the beat, all 25 patterns, and a 7-day practice streak.

### Is this a substitute for a music teacher?

No. It is a home practice tool, not a teacher, therapist, or safety device. Feedback is automatic and can be wrong. For real instruction, learn from a qualified music teacher, linked on the app's Resources page.

### Who is it for?

Anyone learning rhythm: beginning musicians, drummers, dancers, singers, or anyone who wants an honest metronome that tells them exactly where their timing drifts.
