Oolimo is the interactive foundational reference for guitar chords – a learning and lookup app that explains chords clearly, supports songwriting, and inspires fresh sounds on the guitar. – No subscription! Pay once – use it forever and receive updates. – Current languages (included in every app): English, German, Spanish, French, Italian, Dutch, Danish, Norwegian, Swedish, Portuguese (Brazil), Portuguese (Portugal), Chinese (Simplified), Indonesian, Japanese. Learn guitar chords and chord symbols as used by professional guitarists in modern pop, rock and jazz – including complex jazz chords. Let the Chord Analyzer name chords you've discovered on the guitar and show you how they are built. – Chord Finder, Chord Analyzer and music theory in one app. – Learn and understand chords – Read chord symbols confidently (including complex jazz chords) – Analyze chords instead of guessing – Apply music theory directly on the fretboard Oolimo clears up nonsense chords and incorrectly or confusingly written chord symbols, and explains with clear logic how chord symbols (chord names) are written unambiguously and how to correctly interpret different notations. When musicians from all over the world play together, it's important that everyone speaks and understands the same language – and that the language is easy and clearly understandable. — The Modules — Chord Finder Find musically meaningful chords instead of random guitar shapes. All fingerings come from a hand-curated database of playable voicings and are intelligently transposed by an algorithm. Every chord adapts automatically to the selected key. With a single tap you can send shapes directly to the Analyzer and explore inversions and different interpretations of the chord. Chord Analyzer Enter any guitar chord into the virtual fretboard and instantly get the correct chord name, including inversions. No "unknown chord" messages thanks to the intelligent recognition algorithm – even for complex chords, slash chords and inversions. The Chord Analyzer also supports alternative tunings (open tunings). Chord Progressions Explore and compare the most important chord progressions with an innovative matrix that visualizes harmonic functions and relationships. Practice the most important progressions systematically in different keys and variations – and master them so well that you can rattle them off in rehearsal to the amazement of your bandmates. Theory Lessons 22 interactive lessons with smart visualizations explain intervals, chord construction, voicings, slash chords, diatonic harmony and all major chord types – from first explorations on the fretboard, through major, minor and dominant 7th to altered, sus, add, 6th and diminished chords. Quizzes Use the quizzes to test and internalize your knowledge through play. The quiz tasks cover many topics: chord construction, intervals, harmonic context, chord types, voicings, tensions and much more.
