Sputter is an easy to use but capable mobile music making app. It has a mobile friendly user interface and requires no previous knowledge to create great tracks.

Instead of emulating traditional desktop music software it uses a mobile friendly approach inspired by more recent mobile offerings. At the same time it is not just a toy, and by exploring the help slides and the app itself you will discover several features uncommon in similar music making apps.

Some of those include:

* Feature complete grid style sequencer.
* Mark different sections of your song with various symbols so they are easily found.
* Choose from 16 different musical scales.
* Built in synthesizer/sampler with ADSR, filter, LFO and other good stuff.
* 10 built in effects: Gainer, Distortion, Bitcrusher, Filter, 3 Band EQ, Tremolo, Flanger, Chorus, Delay, Reverb.
* Effects and synth parameters automation with real time recording.
* Easily change and update whole parts of your song at once.
* Several different time signatures (2/4, 3/4 etc).
* Record any sound through microphone or default input device and use it as an instrument.
* Import your own wave files to create your own instruments.
* Export your song as MIDI or WAV for easy sharing and importing to other audio or video software.
* Export and import songs for sharing and collaborating with other Sputter users.
* Export and import instruments for sharing with other Sputter users.
* No ads.
* No unnecessary permissions.
