# Calc vs ID Lock

The clearest difference is rating: ID Lock at 4.8 against Calc's 3.9. ID Lock also leads on ratings volume (787 vs 28) and update cadence (every 3 weeks vs every 2 months). Calc's advantage is monetization model (free vs subscription) and review sentiment (81% vs 73%). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Calc sells 2 in-app purchases, starting at $0.99 per month and ID Lock sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

ID Lock holds the better App Store score, 4.8 against 3.9. That said, the two scores are not equally well evidenced: ID Lock has 787 ratings behind it against 28, so its average is the more settled of the two. Written reviews complicate that: 81% of Calc's written reviews are positive against 73% of ID Lock's, so the app with the better star average is not the one people write more warmly about.

Calc ships an update every 2 months, ID Lock every 3 weeks. The most recent releases landed on September 20, 2026 and September 23, 2026 respectively.
