# XCalc Calculator vs LockBox

The clearest difference is ads: LockBox at none against XCalc Calculator's shown. LockBox also leads on rating (5.0 vs 4.8) and update cadence (every 6 days vs fortnightly). XCalc Calculator's advantage is ratings volume (5 vs 1) and iOS requirement (13.0 vs 15.0). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. XCalc Calculator sells 3 one-off in-app purchases and LockBox sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

LockBox holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: XCalc Calculator has 5 ratings behind it against 1, so its average is the more settled of the two.

XCalc Calculator ships an update fortnightly, LockBox every 6 days. The most recent releases landed on November 3, 2026 and November 6, 2026 respectively.
