# Panecal Scientific Calculator vs Selector

The clearest difference is ratings volume: Panecal Scientific Calculator at 2K against Selector's 2. Panecal Scientific Calculator also leads on rating (4.8 vs 4.5) and iOS requirement (12.0 vs 16.0). Selector's advantage is review sentiment (100% vs 76%) and update cadence (every 3 weeks vs every 2 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Panecal Scientific Calculator holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Panecal Scientific Calculator has 2K ratings behind it against 2, 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 Selector'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, Selector every 3 weeks. The most recent releases landed on November 11, 2026 and November 3, 2026 respectively.
