# Linus vs Flash

The clearest difference is ads: Flash at none against Linus's shown. Linus's advantage is device support (3 vs 1) and iOS requirement (15.1 vs 26.0). On price, update cadence and in-app purchases there is nothing between them.

Both are free to download. Linus sells 10 in-app purchases, starting at $24.99 per 3 months and Flash sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Linus ships an update every 11 days, Flash every 2 weeks. The most recent releases landed on November 8, 2026 and October 31, 2026 respectively.
