FloatCalculator: Floating Calc

FloatCalculator is a floating calculator that stays on top of other apps. Move or resize its window to calculate or convert without leaving the page you're viewing.

Calculate and convert
• Quick math: Add, subtract, multiply and divide with parentheses and percentages. Preview the result as you type and edit the expression when needed
• Currency converter: Convert with preset currency pairs and swap the direction with one tap. Update exchange rates online, check their reference date or use saved rates offline
• Unit converter: Convert length, area, volume, speed, energy, weight and temperature with preset pairs
• Time zone converter: Enter a date and time or tap Now to convert between preset time zones

Ready when you need it
• History: Reopen past calculations and conversions, or delete entries you no longer need
• Floating window: Move, resize or minimize it to the left or right edge of the screen, and adjust its opacity to suit the app underneath
• Quick access: Tap the app icon to open the floating window, or add a Quick Settings tile
• Personal settings: Turn spoken feedback and scale hints (such as “22 million” or “1 thousandth”) on or off, and choose the haptic feedback strength

FloatCalculator Pro unlocks:
• Your choice of currencies, time zones, and units for each conversion pair instead of the preset pairs
• History search, pinned history, and notes on history entries
• Gilded and Cobalt themes

Basic calculations and conversions with preset pairs are free, and the app has no ads. Pro is available as a monthly subscription or a one-time lifetime purchase. The monthly plan may offer a 7-day free trial.

To use FloatCalculator over other apps, allow “Display over other apps” in Android settings (the permission name may vary by device). Internet access is used to update exchange rates and load purchase options. Exchange rates are reference values and may differ from rates used for transactions.

FloatCalculator requires Android 12 or later.
