Verdict
The clearest difference is rating: RMP at 5.0 against Modizer's 4.4. RMP also leads on monetization model (free vs free with in-app purchases). Modizer's advantage is ratings volume (91 vs 1) and iOS requirement (15.5 vs 17.6). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Modizer sells 3 one-off in-app purchases and RMP sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
RMP holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Modizer has 91 ratings behind it against 1, so its average is the more settled of the two.
Modizer ships an update monthly, RMP every 6 weeks. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
