FretTune - Guitar Tuner
Tune, Practice & Play Guitar
Free · Designed for iPad. Not verified for macOS.
FretTune turns your iPhone into a complete guitar practice studio. Strum chords, pick individual strings, explore the fretboard, tune your real guitar, keep time with a metronome, and record your ideas whenever inspiration hits.
The app is built for guitar players who want a practical tool they can use anywhere. Chord mode gives you quick access to 25 common chords across major, minor, seventh, and color chord groups. Swipe across the strings to strum, tap a single string to pick, use up/down strum controls, or mute the strings with one touch.
Fretboard mode lets you play freely across frets 0 to 12, with real-time note names so you can practice melodies, intervals, riffs, and fretboard memory.
The sound engine uses physical modeling synthesis to create responsive plucked-string tones without relying on large audio files. String vibration animation and haptic feedback make each interaction feel more immediate, while body resonance controls let you shape the tone.
FretTune also includes essential practice tools:
- Microphone tuner with pitch detection, cents display, and in-tune feedback
- Metronome from 40 to 240 BPM with accented beats
- Performance recorder with m4a export and share support
- Five tuning presets: Standard, Drop D, Half Step Down, Open G, and DADGAD
- Capo settings from fret 0 to 7
- Left-handed string layout option
- Fully offline design with no account required
Whether you are warming up, checking a chord progression, practicing timing, tuning before a session, or saving a quick musical idea, FretTune keeps the core tools in one simple app.
