CHORD FINDER You know how to play it, but what do you call it? Select frets and finger positions to discover the proper name for your chord.

SCALES Improve your technique by choosing from thousands of scales, modes and arpeggios to practice. Try multiple positions and alternate tunings to boost your versatility. Use "big stretches" for unique, challenging fingerings.

TUNER Keep your instrument in tune with a professional-grade digital tuner, powered by Audiofile Engineering's precise AETune™ pitch detection technology. Choose between strobe or needle interface and access dozens of presets.

METRONOME Keep in time with a hyper-accurate and visually stunning digital metronome. Set tempos numerically or by tapping the touch screen. Choose from multiple sounds and time signatures.

User Reviews

Users praise the app for an easy tuner, accessible metronome, beginner-friendly chord diagrams, and scales, plus its free, all-in-one practice tools. However, the chord finder is often unstable and unreliable, with misrecognized or “no chord” results. Tuner pitch can be inaccurate or transposed, and updates/design changes have reduced usability, with several stability issues reported. Overall, it remains useful for learning and practice, but reliability varies across reviews.

Pros

Easy-to-use tuner.
Metronome is easy to access and useful for practice.
Chord diagrams are beginner-friendly and the chord finder helps learn and experiment with chords; scales are helpful.
Free to use and feature-rich for tuning, practice, and playing.

Cons

Chord Finder crashes frequently and often fails to recognize common chords (some chords show 'no chord'); many users prefer the older version due to reliability.
Tuner and pitch accuracy are inconsistent (notes can be flat, or chords/scales sound/transposed incorrectly, including whole‑step offsets).
Design/update changes have degraded usability; many users feel the old Planet Waves Guitar Tools was better and that updates introduced instability.
Audio/stability issues on some devices (crashes, occasional loss of sound after events like reboot).

Recent reviews

This is app does a decent job in all its functions. But with the new update it’s requiring me to repurchase the upgrade that includes Buzz Feinten. And there is not “restore previous purchase” button.

Great, easy to use tuner and easy to access metronome. I use the tuner more than my Peterson.

I have had no problems with this app so far. I am also a member of D’addario’s players circle, and I was so excited to see they made an app that I could use with guitar.
