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. ## Key features - Interactive chord finder and analyzer - Chord progression visualization - 22 interactive theory lessons - Chord construction and ear training quizzes - Interactive fretboard and diagrams - Chord playback and note display ## Chart rankings - #88 in Top Paid · Education (US App Store) ## Recent user reviews (10 of 118) All indexed reviews: https://appshunter.io/ios/app/oolimo-guitar-chords/id1463331841/reviews.md ### 5/5 — Best Chord App *2026-08-24, version 2.2.3* I had been using the website and wanted a way to support it - the chord analyzer alone makes for an essential tool. Couldn’t recommend more. ### 3/5 — Website is better *2026-08-07, version 2.2.3* Website is better. I bought it on ipad and it has that weird enlarged look. Also why is it not possible to change scale in chord progression mode? ### 5/5 — Got it for the best chord analyzer/theory tool, ended up recommending it to beginners for LESSONS *2026-07-12, version 2.2.3* It’s the best, finding chords, chord relationships, exploring chords, most importantly naming chords you have found. 10/10 S+ would buy again. I ended up recommending it to a couple buddies because the lessons are really really thoughtful- and has built in quizzes when you’re on a car ride and chord progressions out the wazzoo to experiment with and try out new concepts. ### 5/5 — Excellent *2026-07-08, version 2.2.3* I like that app. I can find variations of all the chords. It's especially great that it tells me the chord names based on the notes I press on the keyboard. ### 5/5 — muy bueno *2026-06-18, version 2.2.1* una app buenísima. de las mejores. ### 5/5 — An amazing app *2026-06-17, version 2.2.1* A really detailed and comprehensive app for those wanting to expand their chord knowledge. My only critique is that I wish I could save progressions I've made in the chord analyzer. ### 5/5 — Best Guitar theory app there is *2026-04-13, version 2.0.1* I’m so grateful for this app! What a gem. Thank you for creating it! My middle aged brain never learned music when it was young, so none of this comes easy. But this app helps. Only thing that would be better is more interactive games and added content. It feels like it’s not being updated much. Still 5⭐️ ### 3/5 — Audio Probleme *2026-04-12, version 2.0.1* Der Ton funktioniert nicht, bitte überprüfen Sie dies mit IOS 26.3.1 (iPhone 16 PRO). Vielen dank ### 5/5 — Alles, was man braucht! *2026-04-07, version 2.0.1* Hallo Oliver, danke für diese App, sie vereint alles, was ich als Gitarrist benötige (und schon immer gesucht habe). Vor allem das schnelle Umschalten zwischen Noten und Intervallen ist total hilfreich. ### 5/5 — Will be great for teaching complex fingerings *2026-03-25, version 2.0.1* This is a very elegantly designed programmed visually, good for incremental chord changes( trills, hammer-ons, pull offs) . I plan on doing screen caps of oddball chords and using that to teach guitarists songs, MUCH easier than wasting rehearsal time. You can create videos, but it’s not as reliably accessible (or as 9x12 visible) as a sheet-of-paper per song in a notebook. ## Frequently asked questions about Oolimo Guitar Chords ### What does the Oolimo Guitar Chords app do?
