One of my favorite ways to enlarge small print or detailed objects is to use video magnifiers or magnifier apps designed for low vision, which offer adjustable magnification levels and more options than a traditional magnifying glass. I use ad-free video magnifier apps for Android multiple times per day (or multiple times per hour) to assist with tasks like reading labels and signs, enlarging exponents/subscripts in equations, browsing menus, checking instructions, or independently accessing too-small print as a visually impaired student. I also use magnifiers for more fun tasks like reading recipes, checking clarinet reeds, zooming in on a magazine or picture book, and so much more — it’s great to have quick access to magnification on a phone or tablet!
Here is a list of free video magnifier apps for Android phones and tablets that are also free of distracting advertisements. Inclusion of an app on this list is not an endorsement or guarantee that it will work across all devices or for all potential use cases; app features and availability are subject to change.
What is a video magnifier?
Video magnifiers (sometimes called CCTVs or electronic magnifiers) use a camera to magnify printed materials, information at a distance, or other physical items, displaying content on a backlit display. Users can adjust magnification power, apply color filters, “freeze” images (which is similar to taking a photo), and adjust the camera position or angle, controlling the magnifier with tactile buttons or other software. Video magnifiers come in several sizes and configurations, including handheld models and desktop models with built-in screens; some models can also connect to a larger screen or external device. Video magnifiers are an example of assistive technology for low vision.
In addition to standalone video magnifier devices, there are smartphone and tablet camera magnifier apps that use the device camera and offer similar video magnifier features, typically controlled with the device touchscreen. Video magnifier apps may be paired with a device stand or other positioning aids for ease of use.

Can I use the camera app for magnifying text or other content? Why use a video magnifier?
One way to quickly enlarge information is to open the Camera app and zoom in or take a photo and use the pinch-to-zoom gesture to further enlarge a photo. Before I found an ad-free video magnifier app that I liked, this is how I would read things like flyers, menus, signs, or other far away items, or I would use the phone camera to take photos of various items, including cables and ports when troubleshooting technology. In order to make some of these images easier to see, I would have to further edit them with filters or spend time adjusting the contrast for individual images. This often led to my camera roll being filled with random photos of objects!
Video magnifier apps are designed for assisting with visual tasks and offer several options for making content easier to read and see, including display filters and adjustable brightness and contrast settings that can be configured separately from the Camera app – this ensures that photos and videos taken in the camera app are not affected by the display filters used for magnifying content. Photos taken in a video magnifier app do not automatically save to the gallery/camera roll, which can help with managing storage, though users have the option to save photos to their device if desired. A video magnifier app is more like a highly customizable magnifying glass than a camera app used for taking photos.
One of the reasons why I created this list of ad-free video magnifier apps for Android is because there are a ton of magnification apps for Android devices that use the camera to make things bigger or easier to see; there are many magnifying apps for Android that have ads that can have unpredictable content or strobe/flashing lights, as well as magnifier apps that have unnecessary permissions or requests for information. As of publishing time, the ad-free video magnifier apps listed below do not require wifi or cellular data and can also be used in airplane mode.

Google Magnifier: Magnifying glass for Pixel devices
Available for Pixel 5 and later, Google Magnifier is a free magnification app that uses the built-in device camera to enlarge content. Magnifier offers several customization options, such as:
- Switch camera: back-facing camera is used by default, option to switch to front-facing camera
- Flashlight for additional illumination
- Zoom in/Zoom out; maximum zoom levels vary depending on the user’s Pixel device.
- Shutter/Freeze Image, which “freezes” the display so the user can zoom in or apply additional filters; similar to taking a photo, except nothing is saved to the camera roll by default. Images can be saved if desired
- Find text in camera view
- Show Controls menu
- Color filters (press button to cycle between filters): inverted, grayscale, yellow/black, yellow/blue, blue/white, red/black
- Adjust contrast

HumanWare Explorē (HWExplore): Video magnifier for Android smartphones and tablets
HumanWare Explorē (also labeled as HWExplore) is a free video magnifier app for Android that magnifies information using the device’s back camera. HWExplore is a minimalist magnifying app that offers the following features:
- Adjustable zoom, configured on slider. The maximum zoom level will vary depending on the device
- Camera icon for saving photos to the camera roll
- Pause icon for “freezing” images for further viewing without saving to the camera roll
- Lightbulb icon, which uses the built-in device flash for additional illumination
It’s worth noting that the Explorē/HWExplore app displayed a single ad for a HumanWare sale when I launched the app on my phone and tablet yesterday, and the HumanWare logo is present at the top of the screen. However, I still included this video magnifier app in this list because there is only a single ad that can easily be closed/hidden and the ad was for HumanWare (not some random company or unrelated app), which is a well-known assistive technology company that offers other types of video magnifiers.

Use video magnifier app with Chromecast/Google Cast on external screen
For users that benefit from a larger screen for magnification, Android devices can be connected to an external display with a wired or wireless connection. Wired displays are less laggy compared to wireless displays; I use a USB-C to HDMI cable for a wired connection on a TV or computer when working with video magnifier apps, and control the magnifier app directly from my phone/tablet. Another option is to use wireless options like Chromecast/Google Cast, or the Wireless Display feature on Windows computers.
For a low-tech option, users can purchase an external screen magnifier, which is a stand that directly enlarges the phone/tablet display and is designed for watching videos.
To add Cast to the Quick Settings menu for screen sharing on Android:
- Swipe down twice from the top of the device screen
- Select the Edit icon, which looks like a pencil
- Browse the list of settings and select Screen Cast, then drag it to the top of the screen
- Rearrange tiles by long-pressing and dragging across the screen to change the order of how they appear
To use screen casting on an Android device:
- Swipe down from the top of the screen
- Select Screen Cast, which will prompt the user to select which device they want to connect to. Make sure both devices are on the same Wi-Fi network
- Select a device from the list. This will show all information on the screen, including notifications
- To stop casting, swipe down from the top of the screen and select Screen Cast again
Mirror Android device to Windows computer:
On Windows:
- Open Windows Settings and select System > Projecting to this PC
- Projection is always off by default. To enable projection, select Available Everywhere on Secure Networks from the drop-down menu
- Select whether devices will have to ask to project to the PC every time a connection is requested, or first time only.
- Select whether devices will have to enter an on-screen PIN for pairing
- Select Launch the Wireless Display app to project to this PC
On Android:
- Go to Settings > Connected Devices
- Select Connection Preferences and either TV or Cast, depending on the device
- Search for display devices. If only Chromecast devices are available, select the three-dot menu to enable wireless display
- Select Windows PC (or the device name for the Windows PC).
- If prompted, type in the eight-digit PIN to connect
- When finished, select “stop sharing”

Can I connect an external camera to Android for low vision magnification?
Not really, no. Although users can connect an external camera to an Android device via Bluetooth, USB OTG, or through third-party apps, none of the video magnifier apps listed in this post (or any of the video magnifier apps for Android I have ever encountered) worked with external cameras. There are cameras that are specifically designed to connect to an Android device with their own proprietary third-party app, but they aren’t designed for use as video magnifiers for low vision access.
That said, some video magnifiers such as the Jupiter magnifier support HDMI input and can connect to tablets and phones, enlarging the phone/tablet display on the video magnifier’s screen. There are also standalone video magnifiers like the MATT Connect that are powered by custom Android tablets.
For additional magnification without an external camera, consider trying a macro lens that clips onto the phone camera or a phone microscope lens.
