# Formulae Pro vs Bankidu

The clearest difference is price: Bankidu at Free against Formulae Pro's $1.99. Formulae Pro's advantage is update cadence (every 4 days vs every 10 days). On ads, in-app purchases, monetization model and device support there is nothing between them.

Bankidu is free to download; Formulae Pro costs $1.99 up front. Formulae Pro sells 3 in-app purchases, starting at $1.99 per 7 days and Bankidu sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Formulae Pro ships an update every 4 days, Bankidu every 10 days. Both last shipped on October 30, 2026.
