CalcCalc

對於Android的一個簡單的科學計算器應用程序有一個不顯眼的攝像頭功能

The application is useful for both your mathematical homework and taking emergency shots (e.g. in sensitive political situations, etc)

Calculator Features:

* White user interface

* Scientific functions

* Algebraic order of operations

* Scrollable user interface (no "Shift" key needed)

* Small and fast download

Discreet camera! Pretend that you are doing a calculation while taking photos (who would suspect?). To use:

* Press the "Volume Down" button.

* Hold your phone for 2-3 seconds (depends on how fast the camera takes to initialise on your phone)

* When you feel a haptic feedback, the picture has been saved.

* The picture is taken secretly. There is no preview window so nobody should be aware. However, it is not possible to change the focus or other parameters. You may want to try a few times to get a good photo.

* I have not tested this function on most phones.

* Obviously, you should not hold your phone like you are taking a photo!
