# Numby vs Formula

The clearest difference is update cadence: Numby at every 2 days against Formula's fortnightly. Formula's advantage is device support (3 vs 1). On price, ads, in-app purchases and iOS requirement there is nothing between them.

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

Numby ships an update every 2 days, Formula fortnightly. The most recent releases landed on October 30, 2026 and October 31, 2026 respectively.
