Verdict
The clearest difference is monetization model: Smart Eye App at free with in-app purchases against App Lock's subscription. Smart Eye App also leads on ads (none vs shown) and review sentiment (91% vs 58%). App Lock's advantage is ratings volume (5.2K vs 47). On price, rating, update cadence and in-app purchases 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. Smart Eye App sells 5 in-app purchases, starting at $5.99 per month 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.
App Lock holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: App Lock has 5.2K ratings behind it against 47, so its average is the more settled of the two. Written reviews complicate that: 91% of Smart Eye App's written reviews are positive against 58% of App Lock's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on October 5, 2026 and October 20, 2026 respectively.
