FloatCalc+ is a floating calculator that stays on top of any app, so you never have to close your shopping, banking or browser screen just to work something out.
The calculator, unit converter and currency converter share one draggable window: type an expression on the built-in number pad, get the answer instantly and copy it to the clipboard. Fold the keypad away when a single line is all you need, or shrink the whole panel to a floating icon that docks to the edge of the screen.
Exchange rates come from the ECB and refresh daily, cached so everything keeps working offline. The floating calculator is free for 60 minutes a day — the time left is shown in the panel's title bar — and a short ad gets you a 24-hour pass when you need more.
Do I have to close my app every time I want to calculate?
No. FloatCalc+ is a floating window that stays on top of other apps, so you can work out a discount or convert a price without leaving your shopping, banking or browser screen. Drag the window where you need it, get your answer, and carry on right where you were.
Where do the exchange rates come from?
From the European Central Bank, refreshed once a day. Settings › General shows the date the rates are from and their source, and updates them on demand. USD, EUR, JPY, GBP, KRW, CNY and 30+ world currencies convert right inside the overlay, and the daily cache keeps it working offline.
How much can I use for free?
The floating calculator is free for 60 minutes a day, and the panel's title bar shows how much of that is left. When you need more, watch a short ad for a 24-hour pass. Pro removes the daily time limit and the ads and adds the remaining unit categories and 30+ currencies, 7 premium themes and full panel customization (opacity, size, width), monthly, yearly or as a one-time lifetime purchase.
