I’m a long-time HN reader, though I don’t post much.

I recently built an iPhone app called Sunny Hours. Living in the UK, I’ve often wanted a weather app that shows, at a glance, when the sun is actually likely to be out.

I built it because I found that existing apps often gave me lots of forecast data, but not a quick answer to a simple question: when is the nicest part of the day/week likely to be?

So the app is built around a sunshine-first view to make that easier to see.

It’s still early, but the app is live and usable now. I’d really appreciate feedback on whether the sunshine-first view is useful, whether the heatmap is intuitive, and what feels missing.
