# Subnet Calculator + vs CompSci Calculator

The clearest difference is in-app purchases: CompSci Calculator at none against Subnet Calculator +'s 4. CompSci Calculator also leads on update cadence (every 3 days vs every 64 months) and rating (4.4 vs 4.0). Subnet Calculator +'s advantage is ads (none vs shown) and review sentiment (73% vs 63%). On price and device support there is nothing between them.

Both are free to download. Subnet Calculator + sells 4 one-off in-app purchases. CompSci Calculator asks for nothing beyond the download.

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.

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.
