Privacy Statement

Everything needs a privacy statement today, you know that...

To be honest, I'm not at all interested in your personal data. This app is not free, but for now it costs you less than inviting me for a drink, therefore it's free of advertisings and I don't even need to collect any statistical data to convince any flack to deliver well payed banners to jangle your nerves. No annoying "upgrade to pro" messages, you already went for pro :-).

The Oolimo app may need access to you divices storage* to be able to store and restore some options you chose or chords you want to remember, not at all to send me nice pictures or tell me anything else about you.

*) for now I am just using "web storage" as storing technology. Your phone may not even ask for that one.

The only thing I'm interested in is that you can get he most out of this app to improve your musical comprehension and playing. I'm super grateful if you like this app and recommend it to others and if I can at least partly meet the expenses of making a living from the Oolimo project. Thanks and good luck!

Day/Night Mode

The Oolimo App is fun to use, wherever you are. The day mode inverts the contrast scheme to increase readability in daylight. Chord diagrams or staves are much sharper in the app, with a nice clean user interface.

Filter Chords in the Chord Finder

With the buttons for the most common chord categories you can find your chord much faster.

Store and Compare

Use the quick storage of the Chord Analyzer to save up to 9 chords to compare them or keep them until you know them by heart.

Find and Analyze

Transfer a chord from the Chord Finder to the Chord Analyzer and

  • see what its inversions are named
  • see the notes of the chords on a staff
  • modify, transpose, extend or reduce the chord

Tuning Manager

The Chord Analyzer also supports open tunings.

In case you don't find your special tuning in the presets, every tuning cam be edited freely. You can reset the tuning later, if needed.


The quizzes are the perfect way to improve your chord and theory knowledge wherever you are, in the underground, waiting room or a break.


On the start screen of the app you can switch to lefthanded mode. The all chord diagrams will be flipped horizontally.
