ReceptionRating · Positive reviews · Number of ratings

Deckset holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: Deckset has 13 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Date T Calc's written reviews are positive against 50% of Deckset's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Date T Calc ships an update every 17 months, Deckset fortnightly. The most recent releases landed on October 20, 2026 and October 24, 2026 respectively.
