# GyroSynth vs 覔音

The clearest difference is price: 覔音 at Free against GyroSynth's $4.99. 覔音 also leads on rating (5.0 vs 4.4) and update cadence (every 3 weeks vs every 12 months). GyroSynth's advantage is ratings volume (37 vs 1). On ads, in-app purchases and device support there is nothing between them.

覔音 is free to download; GyroSynth costs $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.

覔音 holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: GyroSynth has 37 ratings behind it against 1, so its average is the more settled of the two.

GyroSynth ships an update every 12 months, 覔音 every 3 weeks. The most recent releases landed on October 29, 2026 and October 8, 2026 respectively.
