# PCalc Lite vs Calcbot 2

The clearest difference is review sentiment: PCalc Lite at 83% against Calcbot 2's 60%. Calcbot 2's advantage is ratings volume (11K vs 214) and rating (4.7 vs 4.4). 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 Calcbot 2 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Calcbot 2 holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Calcbot 2 has 11K ratings behind it against 214, so its average is the more settled of the two. Written reviews complicate that: 83% of PCalc Lite's written reviews are positive against 60% of Calcbot 2's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on September 28, 2026 and September 30, 2026 respectively.
