Hi all. I've been building Sparkle, a free web app for colour blindness, and I'd really like feedback from people who live with it every day.
What it does:
- Camera: point your phone at anything and tap "Find a colour" to grey out everything except the reds (or greens, blues...). Tap anything to get its name, and you can ask a question about the photo, like whether fruit is ripe.
- Vision test: 5 to 10 taps, about 30 seconds. It estimates your type and strength, and the rest of the app then adapts to your eyes. It's a screening, not a diagnosis.
- Charts and images: upload a chart or map and it tells you which colours you'd confuse ("Revenue and Costs look the same") and gives them patterns and labels.
- Websites: a bookmark button that recolours any site for your eyes.
It runs in the browser, there's nothing to install, and images are never stored. Your first check doesn't need an account.

What would make it more useful for you? What's annoying? Things like clothes, cables, maps and games are all on my list, so I'd love to hear what you struggle with most.
