RunnerCast is a great, single purpose app that tells me one thing: how is the weather for my run?

Prior to RunnerCast, I’d open up the Weather app on my phone and squint at various metrics. Now, I’m presented with a straightforward set of colours on a timeline and declarative sentence about if I should go now. I also appreciate that I can tweak my tolerance for temperature, precipitation, and other weather features to match my preferences.

Another helpful feature is that you can add in upcoming events (like the half marathon shown in the screenshot) to start preparing mentally for whatever is coming up on race day.

I’m fond of apps like these: well designed, specific, and useful.
