## What is Klimper?

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.


Use your Favorite Instrument Apps

It's just more fun to explore and create with those awesome Instrument Apps that are available in the App Store: Klimper supports Inter-App-Audio Instruments like Animoog and Model 15 as well as Audio Unit Instruments like Ripplemaker and Mersenne.

### 2/5 — Poor UX

*2023-10-21*

Unfortunately, I had to reach out to Support to get sound from any track. For example, I had to select an instrument before any sound would come out and this was unintuitive (3 clicks too many in non-obvious places)

When I add a new track, it was nearly impossible to find how to make both tracks at the same time.

Selecting the instrument you want to chord palette to play with was also impossible.

Selecting multiple chords to duplicate as group; calling them verse or chorus or bridge (would be the first things I would’ve thought of) were also not possible.

Great idea for (identifying which chords will go well together, based on a scale given in a song) but poor execution when it comes to actually building songs.

In need of a user experience designer, so that what was obvious developers is also obvious as the rest of the world.

### 5/5 — Connectivity

*2022-11-17, version 1.3.2*

Could u guys enable a feature to allow project files to be transfered from iPhone to Mac 
Not just the midi files?

### 2/5 — A metronome would really help this app.

*2022-03-27, version 1.3*

Ideas would be easier to flesh out. Klimper helps when I have an idea for a chord progression on my morning commute, but it would really be nice if I can get a base for an entire track whenever inspiration strikes. I feel a metronome would make that easier.

### 1/5 — Absolute trash

*2021-04-30, version 1.3*

This is by far the worst music app I have ever used. Customer service is non existent and with each use, there’s a higher degradation of performance.

### 4/5 — Good!

*2021-04-19, version 1.3*

I will make my own Minecraft music disc :D
There are a few hard to explain and annoying bugs though

### 1/5 — Not satistified

*2021-03-10, version 1.3*

I would like a refund. I was expecting way more flexibility within the app. The app is set up pretty basic.

### 1/5 — Klimper doesn’t work

*2021-02-25, version 1.3*

The phone app loaded ok and played ok for a while and then it started producing a very distorted chord sounds and finally it just quit and now doesn’t play at all. Don’t waste your money.

### 5/5 — Worth it

*2020-12-27, version 1.3*

I don’t know how it’s only rated 3 stars. You can make some crazy stuff on here. Although I wish they’d add more sounds, I love the way it is.

### 1/5 — Buggy, clunky interface

*2020-12-26, version 1.3*

Skip this one - not worth 8.99 to do something you can already do in free apps much more easily. Pick a chord progression or looper free app and it will save you some $

### 2/5 — Keeps crashing

*2020-12-23, version 1.3*

Please fix
