GyroSynth is a finalist in 'Most Innovative App' category at the 2010 Best App Ever Awards (148apps).

GyroSynth is a gesture driven music synthesizer, which takes full adventage of the gyroscope. You can play and modulate the sound by moving your hand through the air - just like the legendary Theremin instrument.

GyroSynth makes use of the gyroscope to measure true roll, pitch, and yaw and translates them to sound parameters like pitch, volume, modulation or filter cutoff. Thanks to phenomenal accuracy (2000 degrees), you can play melodies perfectly in tune.

Minimum requirements: iPhone 4 or iPod Touch 4th generation


- Synthesizers: vocal (formant synthesizer), sine wave , square (PWM modulation), saw, granular sample player with recording function and R2D2 - experimental FM modulation
- Effects: delay and boost
- Several control modes
- Included musical scales allow you to effortlessly play in several styles
- Built-in recorder and player with overdub function

Wonderful new instrument.

This thing is just awesome. Update please! It needs more features. There needs to be option of all octaves available at once- middle C reset location and choice over sensitivity and pitch change direction. A realtime display of note and sharp/flat. Vibrate at pitch change option- Screen touch buttons/surfaces options for manipulation live. Add reverb and control over reverb/delay parameters. More midi control options. Please consider these ideas and update this app.

Very happy!

I have loved this app forever but was pretty bummed when it didn't work with iOS 8. Now it does!!! Woo Hoo!
Just one thing though is I've never been able to get the sampler to actually record from my mic input. Not on the previous version or this one. Other than that I absolutely love it.

Love it!

Playing with this for hours from time to time. Would be pity if it couldn't run on iOS 11. Hope for updates.
