# Sift vs Aphelion

The clearest difference is update cadence: Aphelion at every 2 days against Sift's every 6 days. Aphelion also leads on iOS requirement (16.0 vs 26.2). On price, ads, in-app purchases and device support there is nothing between them.

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

Sift ships an update every 6 days, Aphelion every 2 days. The most recent releases landed on November 9, 2026 and November 10, 2026 respectively.
