Oolimo – The Guitar Chord BibleLearn, understand and master guitar chords like never before.
Oolimo is the interactive learning and reference app that helps you finally make sense of chord symbols, chord names, and harmonic relationships on the guitar. Created by guitarist and developer Oliver Mochmann, Oolimo unites musical depth with clarity and usability—turning theory into something you can actually see, hear, and understand.
Why Oolimo is different?
The web is full of chord charts and tutorials—but few explain why chords work the way they do.
Oolimo fills this gap with a structured, unified, and accurate approach to chord theory. Think of it as a “foundational work” for guitar harmony—clear like a math framework, but engaging like a creative playground. Whether you’re a beginner or an experienced player, you’ll gain lasting insight instead of fragmented tips.
Main modules:
Chord Finder
Discover chords that really make musical sense. All shapes come from a manually curated database of usable voicings, transposed intelligently by an algorithm that knows real-world theory. Each chord adapts automatically to your selected key. Transfer shapes to the Analyzer with a single tap.
Chord Analyzer
Enter any fingering on the virtual fretboard and get the correct chord name instantly—no “unknown chord” messages. Supports standard and open tunings (chord analyzer only). Includes advanced notation options (slash chords, double accidentals, enharmonics) and shows all notes on the staff.
Chord Progressions
Explore, compare, and learn common and essential progressions with an innovative matrix that visualizes harmonic functions and relationships. Practice them in all keys and contexts.
Theory Lessons
22 interactive lessons including smart visalisations explain intervals, chord construction, voicings, slash chords, diatonic harmony, and every major chord type—from major, minor, and dominant 7 to altered, suspended, add, sixth, and diminished chords.
Quizzes
Test your knowledge and train your ear anywhere. The quizzes cover chord construction, intervals, harmonic context, chord types, voicings, tensions, and more—learning through play.

Amazing app, has really helped me learn chords and different ways to play them. I just wish there was the option for 7 strings and higher.

Great app, I used to use the web version, but as soon as I found out about the mobile version, I bought it. I just found that would be nice to have an option to save the favorite chords.

Doesn't have the part I bought the app for. I'm looking for an app that shows chords in different tunings, for example Drop D, Double drop D etc. This can be set in the chord analyser but that doesn't help. To see a diagram of the chord I want in a different tuning is not available, but when you read the ad before purchasing, it looks like it has this function. Disappointing, no apps seem to be able to offer chord diagrams in alternative tunings.

This app should be a tool for any musician. I'm studying chord theory and am a new music writer. This app is worth every penny. The only two additions I hope for in the future for this app is a more direct way of seeing the inversions of each type of chord and a feature where you're able to punch in a chord progression...for the writer side of things . Besides that this app seriously delivers invaluable immediate information on chords, its all there. There's a site you can try this out for free.

Best couple of bucks I've ever spent on an app. I bought it mainly to identify and find chords but I ended up having a lot of fun with the quizzes, which surprised me. I wish there were more or perhaps have them randomly generated somehow. One nice addition would be some tools to help learn notes on the fretboard. As it stands is a very slick and usable app and we'll with the low asking price.

I love this app, its great for finding your way around the fretboard and all its hidden chords. I'd love if you could implement the changing of your tuning in the chord finder too, as it would really help to learn other tunings. For example playing around with drop d it can be a bit confusing working out the change in your bass note (2 semitones down) without a clear picture.

Amazing app, have nothing negative to say. Have you ever thought of adding a feature where you can create and save chord progressions, I'm aware of the ability to save chords I'm more so thinking progressions as a whole. I often use Oolimo to create different chords/inversions and I would love to be able to create unique progressions on the go.

The only app I've found that will name the weird chords I play. For me, totally worth the money just for that one feature.
