About Oolimo Guitar Chords
Learn, 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.
General features:
Interactive fretboard and chord diagrams with note and interval display
Playback of chords or single notes
Switchable between detailed or compact chord names
Day/night mode and left-handed mode
Languages: German, English, Spanish

Tried them all, this is the best
I’m probably what you’d call an intermediate player, not a flashy soloist or anything. Most guitar apps seem to be for beginners or people who want to be shredders. For everyone who needs a great reference tool, this is the one. This has been everything that I need. Switching from playing e standard to c standard made things challenging to me, but this app has helped more than every single other one I’ve tried.

love the app!
I’ve been getting back into music and I’m extremely rusty with theory. This app has helped catapult me back into the world of music without needing to read a bunch of literature. However, there is one bug I would like to report. I did use the email address as well to submit a report. Whenever I leave the app and come back, the audio is muted and I have to hard close the app to fix it.
