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. A finalist in 'Most Innovative App' category at the 2010 Best App Ever Awards (148apps). GyroSynth has been used in numerous live jams and performances (e.g., Mindex) FEATURES - 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 "There isn’t too much more to say about GyroSynth other than wow!"

Verdict

The call

The clearest difference is review sentiment: Radio at 100% against GyroSynth's 73%. Radio also leads on update cadence (every 3 months vs every 12 months). GyroSynth's advantage is rating (4.4 vs 4.0) and ratings volume (37 vs 6). On price, ads, in-app purchases and monetization model there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

GyroSynth costs $4.99 and Radio $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

GyroSynth holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: GyroSynth has 37 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 73% of GyroSynth's written reviews are positive against 100% of Radio's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

GyroSynth ships an update every 12 months, Radio every 3 months. The most recent releases landed on November 1, 2026 and October 27, 2026 respectively.
