Verdict

The call

The clearest difference is ads: Ear Spy Apps at none against Calculator Lock's shown. Calculator Lock's advantage is update cadence (every 2 weeks vs every 5 weeks) and ratings volume (6.1K vs 1.2K). On price, rating, review sentiment and in-app purchases there is nothing between them.

Both are free to download. Calculator Lock sells 7 in-app purchases, starting at $1.99 per 7 days and Ear Spy Apps sells 4 in-app purchases, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Calculator Lock holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Calculator Lock has 6.1K ratings behind it against 1.2K, so its average is the more settled of the two. Written reviews complicate that: 76% of Calculator Lock's written reviews are positive against 80% of Ear Spy Apps's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Calculator Lock ships an update every 2 weeks, Ear Spy Apps every 5 weeks. Both last shipped on September 23, 2026.
