# CATCheckpoint vs App Lock

The clearest difference is ads: CATCheckpoint at none against App Lock's shown. CATCheckpoint also leads on iOS requirement (12.0 vs 16.0). App Lock's advantage is update cadence (fortnightly vs every 2 months). On price, in-app purchases and device support there is nothing between them.

Both are free to download. CATCheckpoint sells 1 one-off in-app purchase and App Lock sells 6 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

CATCheckpoint ships an update every 2 months, App Lock fortnightly. The most recent releases landed on October 7, 2026 and October 24, 2026 respectively.
