# Kabe vs Sift

The clearest difference is update cadence: Kabe at every 2 days against Sift's every 9 days. Kabe also leads on iOS requirement (16.0 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Kabe sells 4 one-off in-app purchases and Sift sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Kabe ships an update every 2 days, Sift every 9 days. Both last shipped on October 31, 2026.
