# CASIO fx vs Formulae

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

Both are free to download. CASIO fx sells 1 in-app purchase, starting at $1.99 per month. Formulae asks for nothing beyond the download.

CASIO fx ships an update every 6 months, Formulae fortnightly. The most recent releases landed on June 10, 2026 and September 20, 2026 respectively.
