Mac

Native Mac screen magnifier for low vision: centered zoom, focus tracking, high contrast and up to 20x magnification. Try free for 7 days. I was born with a visual impairment. For 30 years, I've navigated computers with low vision — relying on magnification tools every single day just to read, work, and stay independent. In all that time, I never found the features I truly needed — so I built them myself. ScreenZoomer is not designed from assumptions. It's designed from a lifetime of lived experience as a user who depends on these tools. I want to develop this app based on YOUR needs. If there's a feature that would make your daily life easier, let me know — I'm building this for our community. THE FEATURE I ALWAYS MISSED • Edge-to-Center Panning: Move any point on your screen — even the far corners and edges — to the center of your display. No more struggling to click tiny targets at screen borders. Every pixel becomes reachable, right where your eyes are strongest. MAGNIFICATION • Zoom from 1x to 20x with smooth, animated transitions • GPU-accelerated rendering via Metal for fluid 60 FPS performance • Precise zoom control via keyboard shortcuts, on-screen buttons, or manual input INTELLIGENT TRACKING • Follow Mouse Cursor: The magnified viewport automatically tracks your pointer • Follow Keyboard Focus: Viewport follows the text cursor as you type • Both modes can be toggled independently during use CURSOR ENHANCEMENTS • Multiple cursor shapes: System, Large Arrow, Crosshair, Circle • Cursor scaling from 1x to 8x with customizable colors • Highlight ring, inverted color circle, and pulsing halo effects to never lose your cursor COLOR INVERSION • Four professional inversion methods optimized for different content: - Classic RGB for high-contrast reading - HSL for general UI use - CIELAB for photographs and designs - OkLab for color-coded content and design tools SCREEN POSITION BOOKMARKS • Save screen positions as bookmarks with custom keyboard shortcuts • Instantly move the magnified viewport to saved screen locations with smooth animation • Useful for frequently used areas such as menus, toolbars, form fields, and document regions VIEWPORT CONTROL • Temporary Overview: Hold a key to see the full screen at 1x, release to return • Arrow key panning for precise manual viewport movement • Edge-to-center navigation helps bring hard-to-reach screen areas into your preferred reading zone TEXT OVERLAY • Vector-quality text rendering at extreme zoom levels • Overcomes pixelation by re-rendering UI text with native fonts SCREEN SHARING CONTROL • Toggle whether others see your magnified or unmagnified screen • Useful for presentations and remote support sessions FULLY CUSTOMIZABLE • Remappable keyboard shortcuts for magnification and viewport controls • Hold keys for temporary overview • Settings sync across your Apple devices via iCloud ACCESSIBILITY-FIRST • Full VoiceOver support throughout the app • High-contrast interface with large controls • Built-in permission guidance shown only when a selected feature needs a system permission SUBSCRIPTION Your subscription supports an independent, visually impaired developer and funds ongoing development driven by community feedback. • 7-day free trial with access to the App Store version's features • Monthly and yearly plans available Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://chabasan.com/privacy/
