# Span Calc vs Framify

The clearest difference is rating: Framify at 3.7 against Span Calc's 2.9. Span Calc's advantage is review sentiment (30% vs 0%) and ratings volume (15 vs 3). On price, update cadence, ads and in-app purchases there is nothing between them.

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

Framify holds the better App Store score, 3.7 against 2.9. That said, the two scores are not equally well evidenced: Span Calc has 15 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 30% of Span Calc's written reviews are positive against 0% of Framify's, so the app with the better star average is not the one people write more warmly about.

Span Calc ships an update every 10 days, Framify every 2 weeks. The most recent releases landed on September 29, 2026 and September 28, 2026 respectively.
