## What is Chromono?

Chromono is a "color splash" app that turns your photos and videos black & white while keeping just one color vivid.

Simply tap the part you want to keep. One color stands out against a monochrome world, letting anyone easily create striking, cinematic, poster-like shots — from photos and video alike.

■ Three easy steps
1. Choose a photo (or video)
2. Tap the screen to pick the color to keep (eyedropper)
3. Finish, export, and share

■ Features
- Pick colors by tapping ("eyedropper"), or intuitively with the hue ring
- Fine-tune the kept color's range and feathering
- Layer on Crisp, Cartoon, or Painting styles
- Clean up spillover with the Grayscale Eraser
- One-tap "Compare original" to see before and after
- Export in high quality at the original resolution
- Video color splash supported (Pro)
- iPhone / iPad, with light and dark mode

■ Great for
- Creating stylish, share-worthy photos
- Making a "signature color" pop — a red umbrella or blue sky in a black & white scene
- Adding striking color accents to video, too

■ Pricing
Chromono is free to use (ads are displayed). Purchasing the one-time "Chromono Pro" removes ads, exports without a watermark, and unlocks video color splash. Because it's a one-time (non-consumable) purchase, you can restore it after switching devices or reinstalling, as long as you use the same Apple ID.

All photo and video processing happens entirely on your device; your edited data is never sent externally.

Feedback, requests, and bug reports are always welcome at chromono.app@gmail.com.
