# Poseidon Synth vs Xoraphone

The clearest difference is price: Xoraphone at Free against Poseidon Synth's $7.99. Xoraphone also leads on rating (5.0 vs 4.0) and update cadence (daily vs every 4 months). Poseidon Synth's advantage is ratings volume (33 vs 2) and review sentiment (59% vs 50%). On ads and in-app purchases there is nothing between them.

Xoraphone is free to download; Poseidon Synth costs $7.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Xoraphone holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: Poseidon Synth has 33 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 59% of Poseidon Synth's written reviews are positive against 50% of Xoraphone's, so the app with the better star average is not the one people write more warmly about.

Poseidon Synth ships an update every 4 months, Xoraphone daily. The most recent releases landed on August 4, 2026 and June 1, 2026 respectively.
