# DayCalc vs Ordinary Calculator

The clearest difference is in-app purchases: Ordinary Calculator at none against DayCalc's 4. Ordinary Calculator also leads on update cadence (every 8 days vs every 3 weeks) and iOS requirement (11.0 vs 15.0). DayCalc's advantage is ratings volume (128 vs 35). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. DayCalc sells 4 one-off in-app purchases. Ordinary Calculator asks for nothing beyond the download.

Ordinary Calculator holds the better App Store score, 4.9 against 4.7. Both are backed by a comparable volume of ratings — 128 and 35 respectively. Written reviews complicate that: 87% of DayCalc's written reviews are positive against 82% of Ordinary Calculator's, so the app with the better star average is not the one people write more warmly about.

DayCalc ships an update every 3 weeks, Ordinary Calculator every 8 days. The most recent releases landed on November 11, 2026 and November 7, 2026 respectively.
