# PCalc Lite vs Calculator HD Pro Lite

The clearest difference is in-app purchases: Calculator HD Pro Lite at none against PCalc Lite's 11. Calculator HD Pro Lite also leads on ratings volume (52K vs 214) and rating (4.6 vs 4.4). PCalc Lite's advantage is ads (none vs shown). On price, review sentiment, update cadence and device support there is nothing between them.

Both are free to download. PCalc Lite sells 11 one-off in-app purchases. Calculator HD Pro Lite asks for nothing beyond the download.

Calculator HD Pro Lite holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Calculator HD Pro Lite has 52K ratings behind it against 214, so its average is the more settled of the two. Written reviews complicate that: 82% of PCalc Lite's written reviews are positive against 77% of Calculator HD Pro Lite'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 October 18, 2026 and October 22, 2026 respectively.
