# PCalc Lite vs Calculator +

The clearest difference is ads: PCalc Lite at none against Calculator +'s shown. PCalc Lite also leads on device support (4 vs 2). Calculator +'s advantage is update cadence (every 4 days vs every 2 months) and ratings volume (10K vs 214). On price, rating, review sentiment 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 12 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Calculator + holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Calculator + has 10K ratings behind it against 214, so its average is the more settled of the two. Written reviews point the same way: 83% of PCalc Lite's written reviews are positive against 85% of Calculator +'s.

PCalc Lite ships an update every 2 months, Calculator + every 4 days. Both last shipped on September 24, 2026.
