# Motion Synth vs Flynth

The clearest difference is rating: Flynth at 4.3 against Motion Synth's 3.5. Flynth also leads on device support (4 vs 2). Motion Synth's advantage is in-app purchases (none vs 1) and review sentiment (73% vs 50%). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. Flynth sells 1 one-off in-app purchase. Motion Synth asks for nothing beyond the download.

Flynth holds the better App Store score, 4.3 against 3.5. Both are backed by a comparable volume of ratings — 40 and 55 respectively. Written reviews complicate that: 73% of Motion Synth's written reviews are positive against 50% of Flynth's, so the app with the better star average is not the one people write more warmly about.
