Questions

Why doesn’t Flux ask for my bank login?

Bank connections break outside a few countries and import messy merchant names days late. Logging from Flux’s home-screen widget takes two taps and keeps your credentials private.

Does it work offline?

Yes. Everything saves to your phone first, so it works on flights and subways, then syncs to your account when you’re back online.

Which currencies are supported?

15 currencies out of the box, including USD, NPR, INR, EUR, GBP, JPY, CAD, AUD, and SGD, formatted with native symbols and decimals.

Can I export my records?

Anytime. Export clean CSV spreadsheets or formatted PDF statements filtered by any date range.
