# Kalkyl vs DayCalc

The clearest difference is ads: Kalkyl at none against DayCalc's shown. Kalkyl also leads on ratings volume (717 vs 128). DayCalc's advantage is rating (4.7 vs 4.5) and review sentiment (87% vs 75%). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Kalkyl sells 1 in-app purchase, 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 4.5. That said, the two scores are not equally well evidenced: Kalkyl has 717 ratings behind it against 128, so its average is the more settled of the two. Written reviews point the same way: 75% of Kalkyl's written reviews are positive against 87% of DayCalc's.

Kalkyl ships an update every 5 weeks, DayCalc every 3 weeks. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
