# Lambda vs CPU

The clearest difference is ads: Lambda at none against CPU's shown. CPU's advantage is update cadence (daily vs every 2 days) and iOS requirement (15.6 vs 17.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Lambda ships an update every 2 days, CPU daily. The most recent releases landed on September 23, 2026 and October 3, 2026 respectively.
