# PCalc Lite vs Calculator

The clearest difference is rating: Calculator at 5.0 against PCalc Lite's 4.4. Calculator also leads on review sentiment (100% vs 82%). PCalc Lite's advantage is ratings volume (214 vs 2) and iOS requirement (15.0 vs 18.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. PCalc Lite sells 11 one-off in-app purchases and Calculator sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Calculator holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: PCalc Lite has 214 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 82% of PCalc Lite's written reviews are positive against 100% of Calculator's.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 31, 2026 and October 24, 2026 respectively.
