# RT60 vs SquareSynth 2

The clearest difference is price: SquareSynth 2 at $9.99 against RT60's $34.99. SquareSynth 2 also leads on rating (4.1 vs 3.4) and update cadence (monthly vs every 6 months). On review sentiment, ads, in-app purchases and monetization model there is nothing between them.

RT60 costs $34.99 and SquareSynth 2 $9.99 up front. Neither carries in-app purchases, so what you see is what you pay.

SquareSynth 2 holds the better App Store score, 4.1 against 3.4. That said, the two scores are not equally well evidenced: SquareSynth 2 has 37 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 67% of RT60's written reviews are positive against 63% of SquareSynth 2's, so the app with the better star average is not the one people write more warmly about.

RT60 ships an update every 6 months, SquareSynth 2 monthly. The most recent releases landed on September 21, 2026 and September 26, 2026 respectively.
