This version fixes some bugs and adds different hourly forecast filtering.

Automatic settings! The Runcast can scan your workout history, analyze the weather you’re most likely to run in, and recommend settings based on what it finds. Humidity! Now you can use the humidity to evaluate your running weather. UV Index can now be omitted from your Runcast calculation. Filter the hourly forecast by good times to run only. Weekly forecast chart. The week’s upcoming weather is now represented as a graph, giving you a better idea of what part of the week will be better for running. Better Liquid Glass style integration!

It’s been a while! New for iOS 26 and 2026, we have a new look calling back to the original Runcast, updated for Liquid Glass. Now you can choose to have a lovely background image matching your current weather and time of day. There are some bug fixes in there too. Enjoy!

New setting! Pro users can now specify a precipitation intensity, as well as a precipitation chance. For example, if you're ok with any chance of light rain, but you prefer to stay home if the chance of moderate rain is too high, you can set your rain settings to 25% chance of moderate rain. Let us know how this precip setting works for you! The minute-by-minute rain chart now shows the intensity of rain for each minute by how bold the line is for that minute. This version also includes bug fixes and some iOS 18 compatibility fixes.

This version includes some bug fixes and the groundwork for some new running preferences features, coming soon!

The Runcast 4.0 is all new! It was time for a refresh, like a spring rain washing over the app and making everything better. Notable features: • Up-to-the-minute precip forecast (Pro only) • Hourly condition chart that lets you see the next 24 hours of running weather in the context of your settings (Pro only). Non-pro users get to see the overall runnability score. • Fresh new colors • UV Index settings so you don't get burned (sorry) (Pro only) • Saved locations list shows the current temp and conditions for each location
