# Panecal Scientific Calculator vs Unit Convert

The clearest difference is in-app purchases: Panecal Scientific Calculator at none against Unit Convert's 1. Panecal Scientific Calculator also leads on ratings volume (2K vs 15) and iOS requirement (12.0 vs 15.6). Unit Convert's advantage is ads (none vs shown) and review sentiment (100% vs 76%). On price, rating, update cadence and device support there is nothing between them.

Both are free to download. Unit Convert sells 1 one-off in-app purchase. Panecal Scientific Calculator asks for nothing beyond the download.

Panecal Scientific Calculator holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Panecal Scientific Calculator has 2K ratings behind it against 15, so its average is the more settled of the two. Written reviews complicate that: 76% of Panecal Scientific Calculator's written reviews are positive against 100% of Unit Convert's, so the app with the better star average is not the one people write more warmly about.

Panecal Scientific Calculator ships an update every 2 months, Unit Convert every 3 months. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
