You don't have time to scroll through busy weather apps. WindchillApp has a simple interface with one primary function.

Slide until you see the number you want to find any what-if temperature.

Choose between multiple units including mph, kph, mps, knots, F, and C.

Touch the center button to set sliders for your current conditions.

This app uses the North American windchill model developed by scientists and medical experts from the Joint Action Group for Temperature Indices.

What’s New

Version 2.0.0

2.0 is here!

NEW - You can now pick speed and temperature units independently! I've also added requested mps and knots.
NEW - Share an image of the current windchill settings with your friends! (Btw, did you know that I'll send you an ad-free code when you share the app. Email me!)
NEW - Tap on either side of the slider for fine-grained control
IMPROVED - Sliders are more condensed but have more deceleration after flicking.
IMPROVED - Settings screen is redesigned for easier unit selection.
IMPROVED - All numbers now use a fixed with which means no more jumping/shifting around when moving past narrow numbers.
IMPROVED - Most of the app has been updated or rewritten to easier maintenance, though the core functionality is the same.

Exactly what I wanted

So many great weather apps available, packed with all the myriad data you could ever want. But what was missing from those is a simple, easy to read app that showed the one thing we need the most at a glance without scouring and scrolling through forecasts, air quality reports and UV ratings - the wind chill for my current location, front and center, bold and big.

I’m sure runners and other outdoor, athletic types who are always on the go and don’t have time for scrolling through the usual weather info will find the oversized font and simple “at a glance” interface as appealing as I do. This is especially true when I struggle to get my two young children simultaneously bundled up for the bus stop on cold mornings when I barely have time to make sure their hats are securely covering their ears before they bound out of the house at full speed into the frozen tundra of the Greater Chicago Area.

A great app! Love it. Thank you!

Would be even better if.....

Truly a great app for knowing the actual temp when wind picks up
My only complaint is that I’m having an issue with my screen layout and cannot find anyway to get help or direct support, there is no contact link
