Verdict
The clearest difference is review sentiment: Calculator at 67% against Calctan's 29%. Calculator also leads on in-app purchases (none vs 1) and ads (none vs shown). Calctan's advantage is rating (4.5 vs 4.0) and ratings volume (61 vs 4). On price, update cadence, device support and iOS requirement 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. Calctan sells 1 one-off in-app purchase. Calculator asks for nothing beyond the download.
Calctan holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Calctan has 61 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 29% of Calctan's written reviews are positive against 67% of Calculator's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on October 11, 2026 and September 25, 2026 respectively.
