Oolimo – The Guitar Chord Bible 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 }

So many of these apps are filled with so much junk. Tabs, social media, gamification, etc. Oolimo is the opposite. It is a Bible of chords and tonal theory that expends all its efforts in giving you every detail of a chord you could ever possibly want. I think it’s brilliant and worth every penny.

After using oolimo web for years as a student and now as a teacher I was always amazed by the insane quality and convenience of that website. It is just incredible that the site is free and when i discovered i could give a little money for this app version it was an obvious thing to do and a real pleasure. I'll be there for future projects or updates. Thank you so much Oliver !

If you’re hesitant on grabbing this app, Just grab it ! I’ve had this for years, and it’s my number 1 guitar app. I can’t express enough how helpful chord finder and analyzer are for practice and developing your theology knowledge, and connecting it to the fret board. They could make this app price, and it’s worth it.

Trying to decipher my open tunings & what chords im playing with them - hoping oolimo would help but it doesn't cover these tunings! Otherwise great app - if i had one gripe or letdown it would be there are no options to explore open tunings!!! Please work on including these!!!

Per chi non conosce a menadito la teoria musicale, questa applicazione è veramente indispensabile per conoscere gli accordi e costruirli. La consiglio vivamente a chi ama suonare la chitarra.

2.0.1 Fixed issues when the app was installed on desktop devices or MacBooks (not actually intended, but partially possible). Two things were adjusted: Optimized audio code. The samples now use .wav files instead of .mp3. Fixed problems distinguishing between touchscreen and mouse/touchpad input. 2.0.0 Spanish added — selectable for all users (alongside English and German). Fresh icons on the start screen Refined texts, improved explanations Bug fixes and performance optimizations
