Klimper is a mobile music studio with built-in music theory to spark your creativity and speed up your workflow.

Find Chords that Work

In the chord palette your can explore chords that are available in your selected scale. While a chord is played, related chords are highlighted so you can easily find chord sequences that progress smoothly. Once you found a nice chord sequence, you can drag and drop chords into your song to build your composition upon it.
If you want to start your song with a melody and find a suitable chord progression, you can do that just as well: select notes and tap the search icon to show chords that match your melody fragment. It's real fun to experiment, seeing how different harmonic contexts affect the perception of the same melodic fragment.

Create Beautiful Melodies and Flowing Chord Progressions

In the piano roll, notes that are in harmony as well as the chords' root notes are highlighted. This makes it super easy to create leads, arpeggios and basslines and to experiment with different chord voicings to let your chord progressions flowing nicely.

Intuitive Editing

A simple, yet feature rich and context-aware user interface helps you build up your ideas into whole songs:
Group sections into song parts and arrange them via drag and drop.
Duplicate, copy and paste, playback selected notes.

File Export

Export and share your creations with audio file export.
Edit your song in other Apps with MIDI-file export.

Great app, could use some more things

I love the chord progressions that you can make with this app. It shows you chords that work best with each other so I can make chord progressions much better than what my tiny brain can make ;) anyways, this app would be perfect 5 stars if it had some more features. For example: more instruments, a swing rather than simple on the beat time, half steps rather than only using notes in the key, things like these. I would still recommend this for any music lover! Worth the money!

Great potential, missing features and UX issues

First of all, this is immediately one of my favorite chord progression sandboxes. Don’t get me wrong. The fact that it integrates with the minimoog Model D synth app to play the notes and supports Ableton/MIDI output is extremely exciting.

However, there are some significant missing features that I’d expect from an app claiming to take on the scope that it does such as a metronome, a record button, and setting the timing signature. It’s hard to tell how the chord progression will sound until you’ve already dragged the chords to the odd/uncomfortable band at the top of the screen... would honestly be easier to just record it. It’s like the length in bars is too flexible... let me pick the timing signature (e.g. 3/4) and a fixed number of bars for the loop.

Really, I think the UX needs to be rethought a bit and some basic features for recording a track need to be added. With refinement, this could be the best songwriting tool an EDM songwriter could have... right now it feels like more of an open beta. Disappointing to spend $9 on what feels like an unfinished product but I would gladly invest more if the developer(s) stay active.

Exactly what I need

I have been searching for something like this to replace my piano apps and voice memos. I am a composer and spend most my time writing in my studio; however, I needed a quick way to record ideas and compose snippets on the go and at the time an melody pops into my head. Instead of singing, humming into a voice memo or playing my piano app and trying to memorize the part real quick. Anyway, I would only suggest to the dev to add a more practical way of changing tempo and making an option for triplets at a smaller level. You can write quarter note triplets but nothing smaller, forcing you to redesign your note layout, and adjusting the bpm. Regardless, this app is still a perfect app for what I intend to use it for but I could see it being very limited if people were to use it as a platform for full composition.
