# Numerix Calculator vs Formula

The clearest difference is in-app purchases: Formula at none against Numerix Calculator's 1. Formula also leads on update cadence (fortnightly vs every 6 months). Numerix Calculator's advantage is iOS requirement (13.0 vs 17.0). On price, ads and device support there is nothing between them.

Both are free to download. Numerix Calculator sells 1 one-off in-app purchase. Formula asks for nothing beyond the download.

Numerix Calculator ships an update every 6 months, Formula fortnightly. Both last shipped on October 24, 2026.
