# ResyOS vs A

The clearest difference is rating: A at 5.0 against ResyOS's 2.7. ResyOS's advantage is update cadence (fortnightly vs every 5 months) and ratings volume (159 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

A holds the better App Store score, 5.0 against 2.7. That said, the two scores are not equally well evidenced: ResyOS has 159 ratings behind it against 1, so its average is the more settled of the two.

ResyOS ships an update fortnightly, A every 5 months. The most recent releases landed on November 11, 2026 and November 4, 2026 respectively.
