# OpEvol vs Prism

The clearest difference is update cadence: Prism at every 5 days against OpEvol's every 22 months. Prism also leads on monetization model (free with in-app purchases vs paid) and iOS requirement (18.0 vs 26.0). OpEvol's advantage is device support (3 vs 1). On price, ads and in-app purchases there is nothing between them.

Both are free to download. OpEvol sells 1 in-app purchase, starting at $6.99 per year and Prism sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

OpEvol ships an update every 22 months, Prism every 5 days. The most recent releases landed on October 15, 2026 and October 28, 2026 respectively.
