What's New in Chordology

3.3.0

September 25, 2026

Now you can read the instrument your way: switch note labels to intervals and scale degrees, mirror the fretboard and tab for left-handed playing, and adjust playback speed and note length. Plus a real Settings screen, and a Light, Dark, and Auto appearance picker — now on Mac too.

User reviews

used to be a great app, now it’s a horrible app

what else can I say - used to be the best chord app ever, now it’s horrendous after the update

☝🏾🙂🎹👍🏾👍🏾

If it’s not broke then don’t fix it

[“ i have it on my 💻 ipad & 📱 & to be honest even though i’ve studied music theory i dont know what i’d do if it were not for this app. very easy to use. i recommend to others all the time”]

Response from developer

Thanks so much for this review, also for recommending to other people! If you have any ideas for new features, feel free to drop me an email.

Great app for discovering and constructing chords

This app is really solid. I like the UI and features.


One thing I noticed right away:

The voicing displayed on the fretboard doesn’t match the voicing played:

• Each voicing variant sounds identical.
• The played chord is an octave higher than what is shown on the fretboard.

⭐️Adding the ability to hear each chord (and its different voicings) exactly how it’s displayed would go a long way.

⭐️Adding the ability to toggle between displayed numbers and note names would also be awesome (e.g. toggle between displaying “m3rd” vs “Eb” for a Cmin chord).

⭐️Adding functionality to change the color scheme could really benefit some that possess perfect pitch and/or hear notes as colors.

Not Accurate

The app shows various minor chords as major chords and vice-versa. Do not use this app for learning chords.

perfect chord reference app

Super intuitive and convenient to use. All the other apps require scrolling and searching through huge lists of chords but this one gives you everything you need and you just combine them to build the chord.

Response from developer

Thanks for the great review, I’m glad you’ve found it useful!
