# UNdata vs PermrApp

The clearest difference is rating: PermrApp at 5.0 against UNdata's 4.5. UNdata's advantage is ratings volume (11 vs 2) and iOS requirement (12.0 vs 15.1). On price, update cadence, 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.

PermrApp holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: UNdata has 11 ratings behind it against 2, so its average is the more settled of the two.

Both ship on a similar rhythm, roughly every 4 months. The most recent releases landed on September 19, 2026 and June 1, 2026 respectively.
