Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
