# DayCalc vs Numerical³

The clearest difference is in-app purchases: Numerical³ at none against DayCalc's 4. Numerical³ also leads on ads (none vs shown) and ratings volume (1.3K vs 126). DayCalc's advantage is review sentiment (87% vs 75%) and iOS requirement (15.0 vs 18.0). On price, rating, update cadence and device support there is nothing between them.

Both are free to download. DayCalc sells 4 one-off in-app purchases. Numerical³ asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.7 for DayCalc against 4.8 for Numerical³. That said, the two scores are not equally well evidenced: Numerical³ has 1.3K ratings behind it against 126, so its average is the more settled of the two. Written reviews are what separate them: 87% of DayCalc's written reviews are positive against 75% of Numerical³'s.

DayCalc ships an update every 3 weeks, Numerical³ every 2 weeks. The most recent releases landed on October 13, 2026 and October 14, 2026 respectively.
