# Sup vs StackLab

The clearest difference is update cadence: Sup at every 4 days against StackLab's fortnightly. Sup also leads on iOS requirement (15.1 vs 18.6). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Sup sells 3 in-app purchases, starting at $0.99 per 7 days and StackLab sells 3 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

Sup ships an update every 4 days, StackLab fortnightly. The most recent releases landed on October 4, 2026 and October 6, 2026 respectively.
