## What is ChromaTrack?

When you're filming your talent as they're using an iPhone or an iPad, you need the device to show a chroma key you can count on. At Koi, we got tired of setting up chroma key images and tracking markers, and wanted a solution where the talent could actually touch the screen. Plus, we didn't want to have to adjust our sleep mode every time. ChromaTrack makes it easy. Set the screen color, marker opacity, and tracking pattern, then launch. When you’re done, just tap with three fingers to get out of the screen.

## Key features

- Interactive chroma key display
- Adjustable screen color
- Customizable marker opacity
- Selectable tracking patterns
- Easy exit gesture (three-finger tap)

### 5/5 — Exactly what I needed!!

*2021-08-15, version 1.0*

### 1/5 — ???

*2019-08-01, version 1.0*

Absolutely no instructions! I payed 0.99 for what?

**Developer response:** When you launch the chroma key screen, a pop-up explains that you can return to the menu by tapping the screen with three fingers. You can tell the pop-up not to appear again, and you can bring it back later (for example, if someone new is using the app) by returning to the Menu, tapping Settings, and toggling the "Skip instructions before the chroma key" option.
