# Algorithms vs Redeemly

The clearest difference is iOS requirement: Algorithms at 15.6 against Redeemly's 18.0. On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Algorithms sells 3 one-off in-app purchases and Redeemly sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Algorithms ships an update every 3 weeks, Redeemly every 10 days. The most recent releases landed on September 18, 2026 and September 21, 2026 respectively.
