ReceptionRating · Positive reviews · Number of ratings

Calculator83 holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Omega Calculator has 44 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 63% of Calculator83's written reviews are positive against 83% of Omega Calculator's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Calculator83 ships an update every 20 months, Omega Calculator every 2 months. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
