Color Picker (v1.0)

Hello. I'm Android Boy, the chief developer of Smart Tools co,.

Recently, some users have requested a color-meter or a color-selector app. Development is not hard, but I kept putting it off because it was a function that wasn't used much.

Sometimes I had to choose the color of a specific screen when drawing an app design.

When drawing app designs, it was sometimes necessary to select the color of a specific screen. I decided to develop a color picker app with a slight modification of the magnifying glass app. :)

1. Moving - by moving your phone.

2. Touching - by touching the screen.

3. Freezing - after freezing the camera view.

4. Gallery - by loading images stored on your phone.

  Press the white button. The RGB color code is confirmed at the top.
