Verdict

The call

The clearest difference is price: Calculator⁼ at Free against Calculator's $1.99. Calculator⁼ also leads on rating (4.6 vs 4.0) and update cadence (monthly vs every 11 months). Calculator's advantage is in-app purchases (none vs 8) and ads (none vs shown). On device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Calculator⁼ holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Calculator⁼ has 358K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 60% of Calculator's written reviews are positive against 36% of Calculator⁼'s, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Calculator ships an update every 11 months, Calculator⁼ monthly. The most recent releases landed on September 18, 2026 and September 28, 2026 respectively.
