How trust works

Turns your live camera feed into ASCII art, dithering, halftone, lines and voxel visuals, in real time and entirely on your device.

Phosphor Cam turns your live camera feed into ASCII art, dithering, halftone, lines and voxel visuals, in real time and entirely on your device.

Point your camera at anything, pick a style, and watch the world get redrawn as text, dots, ribbons or pixel blocks. Switch styles on the fly without restarting the camera, and fine-tune the look until it feels right.

Five visual styles

  • ASCII: characters mapped to brightness, optionally tinted with the original colors

  • Dither: a retro, print-like bitmap look

  • Halftone: your image rebuilt as a grid of dots

  • Voxel: chunky pixels with a 3D block effect

  • Lines: every row drawn as one continuous ribbon

Make it yours

  • Several ASCII character sets, including blocks, matrix and edges

  • Adjustable cell size, contrast and brightness

  • Color mode, invert, and custom foreground and background colors

  • Live FPS and render time readout

Capture and share

  • Save high-resolution images of what you see

  • Record video of the rendered output

  • Copy the current ASCII art to your clipboard as text

  • Switch between front and back cameras

Private and offline

Everything runs locally. Your camera feed is never uploaded, and the app needs no account, no server and no internet connection. It contains no ads and no trackers.

Phosphor Cam is free and open source under the MIT license.

Release notes

Phosphor Cam v1.3.0 : Mobile Editor Dock

This release brings the full settings panel to mobile, so you can change the look of the camera and Studio without leaving the live preview.

What's New

  • Mobile editor dock: a tabbed dock with Style, Adjust, Effects, Chars, Color and Capture, plus About. It slides up from the bottom, can be collapsed by dragging it down, and keeps the preview visible while you edit.
  • Studio dock: the same dock replaces the old mobile settings sheet, with Presets added as the first tab.
  • Edit from the camera controls: a new EDIT button sits beside COPY on mobile and opens the dock in place of the camera buttons. A compact shutter, flip and mode cluster floats above the dock, so you can keep shooting while it is open.
  • Mobile color controls: Live color, invert, random/swap and the full preset row, with Hue, Saturation and Brightness sliders that preview the color on their tracks, plus a hex field that accepts shorthand (#abc → #aabbcc).

Changed

  • Desktop color picker: the hue/saturation wheel is gone. Desktop now uses the same H/S/B sliders and hex field as mobile, so both layouts behave identically.
  • Dock-aware layout: the dock reports its height to the page, so the camera preview and the floating controls stay clear of it.
  • Sliders: every mobile slider (adjust, effects, capture, color) now uses the same touch-first control with keyboard support and one undo step per gesture.

Fixes

  • Pinch-zooming the page no longer zooms the app UI.
  • Corrected the Studio header position on small screens.
  • The camera preview no longer sits behind the editor dock.
  • The Capacitor appId now matches the Android applicationId (site.aroy.phosphor), so the native build and the web config agree.

Under the Hood

  • Settings UI split into common/, desktop/ and mobile/ modules, with shared color math, sliders and effect metadata.
  • Camera controls split into focused modules (ControlBar, DockCluster, Shutter, ModeSwitch, primitives, styles, types).
  • ESLint and Prettier replaced with oxlint and oxfmt.
