ReceptionRating · Positive reviews · Number of ratings

CompSci Calculator holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: CompSci Calculator has 42 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 73% of Subnet Calculator +'s written reviews are positive against 63% of CompSci Calculator's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Subnet Calculator + ships an update every 64 months, CompSci Calculator every 3 days. The most recent releases landed on October 13, 2026 and October 10, 2026 respectively.
