# GyroSynth vs Radio

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.

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

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.

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.
