# PRO vs EnAPP

The clearest difference is ratings volume: PRO at 108 against EnAPP's 1. PRO also leads on update cadence (every 2 weeks vs every 6 weeks). EnAPP's advantage is device support (3 vs 1) and iOS requirement (11.0 vs 16.0). On price, rating, ads and in-app purchases there is nothing between them.

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

On the App Store both sit at effectively the same score — 4.9 for PRO against 5.0 for EnAPP. That said, the two scores are not equally well evidenced: PRO has 108 ratings behind it against 1, so its average is the more settled of the two.

PRO ships an update every 2 weeks, EnAPP every 6 weeks. The most recent releases landed on October 24, 2026 and October 13, 2026 respectively.
