# RE vs Flash Focus

The clearest difference is ads: RE at none against Flash Focus's shown. RE also leads on update cadence (every 4 weeks vs every 2 months) and iOS requirement (7.0 vs 14.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. RE sells 1 one-off in-app purchase and Flash Focus sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

RE ships an update every 4 weeks, Flash Focus every 2 months. The most recent releases landed on October 10, 2026 and October 7, 2026 respectively.
