Magnifier is a free magnifying glass app for Android smartphones. It allows you to observe and magnify objects, documents, and even text on a smartphone or tablet screen.

You can use your device's camera to magnify an object, and the result will appear on the screen. The magnified image can be saved to your device for future viewing.

If you don't have a smartphone or tablet, you can use your Android phone or tablet as a magnifying glass. Just download the app, and you can use the phone or tablet screen as a magnifying glass to observe objects.

The magnifier app has a built-in light source so you can use it in a dark environment. The app has an adjustable zoom, from 2x to 100x.
