# ClevCalc vs App Lock™

The clearest difference is review sentiment: ClevCalc at 91% against App Lock™'s 19%. ClevCalc also leads on monetization model (free with in-app purchases vs subscription) and rating (4.7 vs 4.5). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. ClevCalc sells 3 in-app purchases, starting at $2.99 per month and App Lock™ sells 6 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ClevCalc holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: ClevCalc has 14K ratings behind it against 2.6K, so its average is the more settled of the two. Written reviews point the same way: 91% of ClevCalc's written reviews are positive against 19% of App Lock™'s.

ClevCalc ships an update monthly, App Lock™ every 5 weeks. The most recent releases landed on November 1, 2026 and October 29, 2026 respectively.
