ReceptionRating · Positive reviews · Number of ratings

Haseba Calculator holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Haseba Calculator has 3.8K ratings behind it against 214, so its average is the more settled of the two. Written reviews complicate that: 82% of PCalc Lite's written reviews are positive against 78% of Haseba Calculator's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

PCalc Lite ships an update every 3 months, Haseba Calculator every 2 months. The most recent releases landed on October 23, 2026 and October 22, 2026 respectively.
