## What is LionPulse?

LionTuner is a tuner + metronome + song speed trainer built for daily practice. Completely free, no ads.

■ Chromatic + 7 instruments
Guitar, bass, ukulele, violin, viola, cello, mandolin presets, plus a chromatic mode for everything else. YIN-based pitch detection accurate to ±1 cent.

■ Metronome with custom sounds
Per-beat strength control (accent / normal / soft / mute) for every sub-beat, up to 16th-note subdivisions. Import your own click samples from any audio file.

■ Song Speed Trainer (new)
Import your own songs and slow them from 10% to 300% — the pitch stays the same. Automatic BPM detection, and an optional metronome click you can practise along with (choose the time signature, subdivision, and sound). Loops, and plays in the background.

■ Practice timer
5-minute to 1-hour sessions with an optional 5-second countdown, configurable loop count and rest gaps. Auto-starts and stops the metronome.

■ Background playback
Look at your sheet music in another app while the metronome/song keeps playing. Control it from the Lock Screen, Control Center, or paired headphones.

Privacy: all audio is processed on your device and never uploaded.

## Version history (last 5 releases)

### 1.0.6 — 2026-09-08

New: Song Speed Trainer
Slow any of your own songs down to practice — the pitch stays the same:
• 10%–300% speed
• Automatic BPM detection, with manual correction (½ / ×2 / ±1)
• Play a metronome click along in time — choose the time signature, subdivision, and sound (including your own custom sounds), and tap to align to beat 1
• Loop playback, plus background & Lock Screen playback
• Import purchased or added songs from your Music library (DRM-protected streaming tracks can't be time-stretched)

Plus UI and stability improvements. Thanks for playing — questions always welcome!

• New "Rhythm Echo": hear a rhythm, tap it back, and get scored (Easy/Medium/Hard + Custom).
• Fixed other audio issues.

・Subdivisions expanded — 32nd notes and sextuplets are now available, giving you finer control over complex rhythms and polyrhythmic patterns.
