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. ### 1/5 — Not Accurate *2026-05-11, version 2.3.1* The app shows various minor chords as major chords and vice-versa. Do not use this app for learning chords. ### 5/5 — perfect chord reference app *2023-10-25, version 2.3.1* 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. ### 5/5 — amazing *2023-09-03, version 2.3.1* this app is just great, big props to the developer for the work they put in. this app helped so much when I was learning about different chords and scales and helps so much now when I am tring to compose and I want a quick way to try different chord progressions and scales. thank you. ### 1/5 — Not A Universal App *2022-09-26, version 2.3.1* I like the variety, however the usability is lacking here. The iPad version is basically a small iPhone UI with borders stretched to the edges to make it seem full screen. You have to pinch your eyes or hold the iPad closer because it’s hard to see and harder to use. The main point of having an iPad version in a music app is to use the extra screen space and processing power. Right now it’s just a lazy effort. ### 5/5 — Beautifully designed app *2022-07-17, version 2.3.1* Interface is beautifully minimal, and easy to understand. So many chord apps are clunky or offer so many options that they’re indecipherable. This has the perfect balance and is eminently useable. ### 5/5 — Fantastic Tool *2021-12-07, version 2.3.1* I can say confidently that this is my favorite chord app on the AppStore. It’s clean, looks good, and is super helpful for looking up stuff like jazz chords. It’s been great for when I have to look up a chord for the guitar or piano, However, I’m primarily a five string banjoist, and I would be overjoyed to have a five-string banjo added as one of the instruments available. I’ve been trying to get into the more modern/jazzgrass type stuff on the banjo, and having a chord catalogue like this for it would be tremendously helpful. Overall though this is a great tool and learning aid, 5/5 ### 3/5 — Good. Could be GREAT *2021-10-24, version 2.3.1* I have this app on my iPhone and Mac and use it often. It's good. But to be GREAT… Add MIDI chord detection (for piano). Then this would easily be a five-star app. Nothing currently on the app store chord-detection as a stand-alone app, and that killer feature would make it a must-have. ## Frequently asked questions about Chordology ### What does Chordology do?
