Oolimo Guitar Chords
Description
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. Current languages (included in every app): English, German, Spanish, French, Italian, Dutch, Danish, Norwegian, Swedish, Portuguese (Brazil), Portuguese (Portugal), Chinese (Simplified). 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.

User Reviews
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⭐️
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.
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.
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.
This does amazing stuff such as analyzing chords, teaching chords theory, etc. The only thing that keeps it from being five stars for me is that when I do the tests, it doesn’t grade them. I am hoping to hear from the developer that I am missing something or it’s something that can be fixed. If it is, I will upgrade my review to five stars. Even with that glitch, I highly recommend this. I will be using it for a long time to come
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.
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.
I’ve been using the web app, but prefer this use on my phone
This app is endlessly useful and extremely well done. One of the most used apps on my phone. Please add 5-string banjo!!!!
I use it all the time. It rules 😎
