Neonizer: Neon Photo Effect1.3.2 - App Store

Neonizer is a real-time camera that turns the world in front of your lens into glowing neon-sign art.

Point your iPhone at anything - a building, a face, a houseplant - and watch its edges light up in vivid pink, cyan, and yellow neon. There's no "edit" step: the finished look is what you see in the viewfinder, so you can frame and light your shot live.

■ Features
. Real-time neon processing powered by OpenCV edge detection
. Three effect modes:
- Line - traces subject outlines with glowing strokes
- Rect - wraps detected regions in neon rectangles
- Circle - highlights detected regions with glowing rings
. Night Mode - drops the background to pure black so only the neon glows
. Adjustable line thickness via slider
. Tap to take a photo, long-press to record video
. Built-in album to review your shots without leaving the app
. Share via the standard iOS share sheet (Mail, AirDrop, Messages, and more)

■ Try it on
. Night streets and signage for a cyberpunk look
. People for glowing line-art silhouettes
. Houseplants and small objects for sci-fi arcade icons
. Anything ordinary, made instantly "shareable"

■ Free, no ads
Neonizer is a free indie project with no ads and no tracking. If you enjoy it, an optional "Support the developer" tip jar lives in Settings. Tips are completely voluntary and unlock no features or content.

■ Requirements
iOS 17.0 or later. Optimized for the iPhone rear camera.
