Popup Calc is a convenient calculator app when you want to do a little calculation while looking at the web or memos. It can be moved and scaled so it does not interfere with the calculation.
Popup Calc is displayed small so that it doesn't get in the way of other apps, but the numbers are separated by digits to make it easier to see.
■ About the function
・ When the digits overflow, click the calculation result to display all digits on a separate screen. Swipe left or right on another screen to scroll the calculation result and see all digits.
-If you long-click the calculation result, the calculation result will be copied to the clipboard.
-Clear all by long-clicking while the one-character erase (→) button is displayed.
-Press and hold the + button to switch to enlargement / reduction mode, and drag to change the size.
■ About authority
-You need the permission to display it on top of other apps. Also, if you are using Android 8.0 or later, a message will be displayed in the notification to the effect that it is displayed on top of other apps. This authority is not used except for displaying Popup Calc.
