# Light Cross vs SAT

The clearest difference is update cadence: SAT at every 9 days against Light Cross's every 9 months. Light Cross's advantage is device support (3 vs 1) and iOS requirement (12.0 vs 16.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Light Cross sells 10 one-off in-app purchases and SAT sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Light Cross ships an update every 9 months, SAT every 9 days. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
