Verdict
The clearest difference is monetization model: Mamoism at free with in-app purchases against App Lock's subscription. Mamoism also leads on ads (none vs shown) and rating (5.0 vs 4.5). App Lock's advantage is ratings volume (5.3K vs 1). On price, in-app purchases, device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. App Lock sells 6 in-app purchases, starting at $4.99 per month and Mamoism sells 1 in-app purchase, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
Mamoism holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: App Lock has 5.3K ratings behind it against 1, so its average is the more settled of the two.
App Lock ships an update fortnightly, Mamoism every 5 days. The most recent releases landed on November 7, 2026 and November 9, 2026 respectively.
