Big Text Magnifier: screen zoom from 1.5x to 8x and a camera magnifier for print
Big Text Magnifier makes small text bigger in two places: on your phone screen, inside the apps you already use, and on paper, through the camera. Tap the floating button at the edge of the screen and Android's built-in screen magnifier zooms in at the level you chose, anywhere from 1.5x to 8x. Tap it again to go back to normal size. The button stays at the edge while you read messages or news, so you don't have to leave the app you're in. You can drag it up or down or move it to the other side, and make it larger if it's hard to hit. On Android 13 and later, phones that support window magnification can enlarge a window over part of the screen. Other phones magnify the full screen. For print, open the camera magnifier and use your phone as a magnifying glass. It goes up to 100x, but past the range of the camera's own zoom it switches to digital zoom, so the image gets softer as you go higher. You can zoom with the volume keys. Phones with a flash get a light, and Freeze holds the picture still so you can set the phone down and read a medicine label at your own pace. There are four filters: Normal, Grayscale, High contrast and Invert. High contrast and Invert make faded print easier to tell apart. Frozen images are kept in memory only and are never saved as photos. Setup is guided step by step, including the part where you switch the service on in Android's accessibility settings, which makes it easier for a family member to help the first time. The "Try it once" screen lets you practice with the button before you need it. If magnification ever seems stuck, the Help screen has a Stop magnification button and explains Android's own shortcuts for turning it off. The app's screens follow your system font size and use large buttons, so they stay readable with low vision. There is a light and a dark theme, and the app can be switched between English, Korean, Japanese, Spanish, Italian and French. Accessibility service disclosure: Big Text Magnifier is an accessibility tool for people with low vision. It uses Android's AccessibilityService API for one purpose, which is to turn the system screen magnifier on and off and set its zoom level. The service is configured without the capabilities to read screen content, take screenshots, perform taps or gestures, or filter key presses, so the app cannot see what is on your screen or what you type, and no information obtained through the accessibility service is collected or shared. You turn the service on yourself in Android's accessibility settings and can turn it off there at any time. Big Text Magnifier needs no account or subscription, and both the screen magnifier and the camera magnifier are free to use.
