Motion Synth's advantage is in-app purchases (none vs 14) and review sentiment (73% vs 53%). On price, ads and device support there is nothing between them.

Both are free to download. Hypertron sells 14 one-off in-app purchases. Motion Synth asks for nothing beyond the download.
Hypertron holds the better App Store score, 4.4 against 3.5. Both are backed by a comparable volume of ratings — 40 and 159 respectively. Written reviews complicate that: 73% of Motion Synth's written reviews are positive against 53% of Hypertron's, so the app with the better star average is not the one people write more warmly about.
Motion Synth ships an update every 4 months, Hypertron monthly. The most recent releases landed on June 11, 2026 and September 23, 2026 respectively.
