Partial Screen

What if you could focus on just one part of your screen without distractions?

Whether you're presenting a slideshow, recording a tutorial, or trying to keep your audience's eyes on a specific area, Partial Screen gives you a simple yet powerful tool—a resizable, draggable overlay that dims everything except the region you want to highlight. No more pointing with a mouse cursor or saying "look at the top right corner." This app turns your Android device into a precision spotlight for any content.

Core tools & how they work

Partial Screen is built around a single, elegantly executed mechanic: a transparent window that you can move, resize, and shape to reveal exactly what matters. The rest of your display is darkened by a configurable dimming layer. You get full control over the spotlight's dimensions—drag any edge to shrink or expand the viewing area, or tap and hold to reposition it anywhere on screen. The app runs as a floating overlay, so it works on top of any other app, your home screen, or even during video playback. No root access is required, and it launches instantly from a notification shortcut or a floating button.

Key advantages for daily use

• Precision spotlight with adjustable dim level – Set the background opacity from 10% to 90% so your highlighted area pops exactly as needed, without blinding your audience.
• Shape presets for different scenarios – Switch between rectangle, circle, or custom freeform shapes to match logos, buttons, or specific UI elements during demos.
• One-tap freeze and hide controls – Lock the spotlight in place to prevent accidental moves, or hide all control handles for a clean, professional look during screen recordings.
