# DayCalc vs Calculator Plus Pro

The clearest difference is review sentiment: DayCalc at 87% against Calculator Plus Pro's 36%. DayCalc also leads on update cadence (every 3 weeks vs every 7 months) and ratings volume (128 vs 35). Calculator Plus Pro's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, in-app purchases and device support there is nothing between them.

Both are free to download. DayCalc sells 4 one-off in-app purchases and Calculator Plus Pro sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Calculator Plus Pro 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 36% of Calculator Plus Pro'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, Calculator Plus Pro every 7 months. Both last shipped on October 24, 2026.
