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.

App is cool and useful however I think a couple added features would make it 5 Stars

I use this app for intonation purposes and it’s really useful for that! However I think it would be much improved if you could implement accidentals easier, (I.e. A7#5) as opposed to chords which are strictly diatonic. Also if the app could loop while the phone is locked that would help me not kill my battery life while practicing. I mainly have been using it for a drone with a metronome so I can’t speak much on the recording functions, but they seem relatively intuitive, especially if you’re new to understanding harmony. It’s cool to be able to visually pair chords with extensions and not have to worry about intervals. I used to use other apps to drone chords but honestly this one is quick and super simple to use, once the app is open you can immediately start, it’s not like it has a long loading time or anything.

Cool App To Drain Your Battery!

All functionality and coolness of this app is overshadowed by the battery eating feature. This app can use other music apps to generate sound which is neat until you close down Klimper and hours later your iOS device tells you it has 25% battery left and you haven’t touched it all day. So you go investigate in the battery tab in settings, and you find the app that Klimper loaded running in the background and somehow it’s still running. The app isn’t found in the “running apps” view for you to shut it down. There’s no clear instruction on how to shutdown this kind of app. Apple and others will tell you not to do hard shutdowns of apps.... yeah, except for when it’s killing your battery. I don’t even know if doing a hard restart will remove it. Deleting it might be the only option and reinstalling. For this reason, you get 1 star. If Apple allowed users to give a negative value of stars, this would get a -5 stars from me. If I could add a screenshot in a review, I would.

I used the Moog Model 15 app that got stuck. I will promptly change my review again once this issue is resolved. I am adding a star for prompt developer support which most apps lack.

Hi. What app did you use it with for sound generation?
Kind regards,

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.
