# Prisms vs JJ Sensei

The clearest difference is update cadence: JJ Sensei at every 4 days against Prisms's every 17 months. Prisms's advantage is device support (3 vs 1) and iOS requirement (12.0 vs 18.6). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Prisms sells 1 one-off in-app purchase and JJ Sensei sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Prisms ships an update every 17 months, JJ Sensei every 4 days. The most recent releases landed on November 3, 2026 and November 5, 2026 respectively.
