# Calculator Max vs DayCalc

The clearest difference is ads: Calculator Max at none against DayCalc's shown. Calculator Max also leads on ratings volume (1.8K vs 126). DayCalc's advantage is review sentiment (87% vs 55%) and rating (4.7 vs 4.3). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Calculator Max sells 2 in-app purchases, starting at $4.99 per year and DayCalc sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

DayCalc holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Calculator Max has 1.8K ratings behind it against 126, so its average is the more settled of the two. Written reviews point the same way: 55% of Calculator Max's written reviews are positive against 87% of DayCalc's.

Calculator Max ships an update every 2 months, DayCalc every 3 weeks. Both last shipped on September 25, 2026.
