# Fluo vs ProCrash

The clearest difference is update cadence: Fluo at every 2 days against ProCrash's every 5 days. ProCrash's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 18.6). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Fluo sells 2 in-app purchases, starting at $7.99 per month and ProCrash sells 1 in-app purchase, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Fluo ships an update every 2 days, ProCrash every 5 days. Both last shipped on October 24, 2026.
