# 1st Calc vs Number Line

The clearest difference is rating: Number Line at 5.0 against 1st Calc's 3.3. Number Line also leads on update cadence (every 6 months vs every 50 months) and iOS requirement (8.0 vs 15.6). 1st Calc's advantage is review sentiment (100% vs 60%) and price ($0.99 vs $1.99). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.

1st Calc costs $0.99 and Number Line $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Number Line holds the better App Store score, 5.0 against 3.3. Both are backed by a comparable volume of ratings — 3 and 5 respectively. Written reviews complicate that: 100% of 1st Calc's written reviews are positive against 60% of Number Line's, so the app with the better star average is not the one people write more warmly about.

1st Calc ships an update every 50 months, Number Line every 6 months. The most recent releases landed on October 8, 2026 and October 12, 2026 respectively.
