FAQ

Do I have to close my app every time I want to calculate?

No. FloatCalc+ works as a floating window that stays on top of other apps, so you can calculate without leaving your shopping, banking, or browser screen.

Where do the exchange rates come from?

It uses real-time ECB (European Central Bank) rates, refreshed daily. You can convert USD, EUR, JPY, KRW, CNY and 30+ world currencies right inside the overlay, and rates are cached each day so it works offline too.

How much can I use for free?

The free tier includes 5 sessions per day, up to 20 minutes each. One default theme is free, while 7 additional themes and some features are available with Pro.
