Sensory Magnus review
A free low-vision tool with adjustable Windows views and camera-based reading on iPhone and iPad.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Sensory Magnus is a free magnification and reading tool for people with low vision, difficulty seeing small text, or visual stress. Its Windows 11 app offers six screen-view styles, while its iPhone and iPad app magnifies printed material through the camera. Both versions are free, with no subscription or account required, making it a straightforward option for individuals looking for magnification across desktop and mobile devices.
On Windows, Magnus supports full-screen, lens, ruler, split-screen, and offset ruler views, with magnification up to 8× in 0.25× increments. Users can set independent colour tints for the magnified and surrounding areas. It also supports the Windows sign-in screen and automatic launch at sign-in through Windows Ease of Access. The published Windows details describe full-screen and lens modes but not docked mode, and the maximum stated zoom may not suit users who need stronger magnification. Windows speech support is described as coming soon rather than currently available.
The iPhone and iPad app takes a different approach: it magnifies with the camera up to 15×, recognizes captured text using on-device OCR, and reads text aloud with word highlighting. Colour, contrast, monochrome, edge enhancement, a torch, and line masking give users additional viewing controls. This makes Magnus a fit for someone who wants both screen magnification and help reading printed text, particularly on Apple mobile devices. Those who need Windows text-to-speech now, or more than 8× Windows magnification, should look for an alternative that meets those specific needs.
