# Sour vs Sukr

The clearest difference is ads: Sour at none against Sukr's shown. Sour also leads on device support (3 vs 1). Sukr's advantage is update cadence (every 5 days vs every 3 weeks). On price, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. Sour sells 2 in-app purchases, starting at $8.99 per month and Sukr sells 3 in-app purchases, starting at $11.99 per month. Whichever you choose, the download price is not the number that matters.

Sour ships an update every 3 weeks, Sukr every 5 days. The most recent releases landed on October 31, 2026 and November 5, 2026 respectively.
