Verdict
The clearest difference is review sentiment: Calculator mini at 100% against Calctan's 29%. Calculator mini also leads on update cadence (every 2 days vs every 3 months). Calctan's advantage is in-app purchases (none vs 1) and rating (4.5 vs 4.2). On price, ads, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Calculator mini sells 1 one-off in-app purchase. Calctan asks for nothing beyond the download.
Calctan holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: Calctan has 61 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 29% of Calctan's written reviews are positive against 100% of Calculator mini's, so the app with the better star average is not the one people write more warmly about.
Calctan ships an update every 3 months, Calculator mini every 2 days. The most recent releases landed on November 6, 2026 and November 7, 2026 respectively.
