This app works as a magnifying glass. A slider makes it possible to change the zoom factor up to x4. The application uses the integrated camera of the device to show a zoomed image on screen. In addition you can use the camera flash as a flashlight for better sight. Have your magnifying glass always with you. Use it to read small text. Use it to analyse tiny objects. It's like a small microscope in your pocket. Please note: Continued use of the flash may dramatically decrease battery life.
