# Space Gate vs App Lock

The clearest difference is price: App Lock at Free against Space Gate's $12.99. App Lock also leads on review sentiment (100% vs 86%). Space Gate's advantage is ratings volume (202 vs 1). On rating, update cadence, ads and in-app purchases there is nothing between them.

App Lock is free to download; Space Gate costs $12.99 up front. Space Gate sells 3 in-app purchases, starting at $2.99 per month and App Lock sells 3 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

App Lock holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Space Gate has 202 ratings behind it against 1, so its average is the more settled of the two.
