Are there any plans to add heat index and windchill to the app (as map layers or near the temperature of 4 day forecast drawer). I would love to have those. Because depending on wind it can feel much colder and depending on humidity it can feel much hotter than actual temperature. I know there are websites where I can enter the two pieces and hit calculate and it will do the formula for me, eliminating need to memorize those lengthy formulas. But it would be nice if your website and app could just display them. That would make me go from 4/5 rating to 5/5 rating.

I would like to see a windchill and heat index map layers.
I would also like to have the advisories/watches/warnings sent to the lockscreen, especially Severe Thunderstorm Warnings and Tornado Warnings sent to lockscreen. To compensate I have installed Emergency by the American Red Cross app just for lockscreen weather alerts, will migrate away from it if you guys were to start sending the advisories/watches/warnings to the lockscreen.
I do have WEA weather category enabled but still rare, sometimes the sirens are blaring but no WEA, and when I was using MyRadar (my only problems with that app is sometimes its most current spot is up to 15 minutes ago, no snow depth, none of some of your unique layers that I like, but has everything else I like) no warnings sent to lockscreen (it does send to lockscreen), but showed us outside of the warned area (by a few miles) which explains the no notification in that case with them.
Currently experiencing where we our in a Red Flag Warning for later today is on the Warnings map layer but not showing at the bottom of the 4 day forecast bar (guessing it won't show up there unless we are during the forecasted timeframe).
I use iqair visual for air quality, it has thresholds notifications and supposedly the most accurate and reliable air quality app, shows one number (instead of your 2 closest stations) that is closest to Current Location, I find one number easier than two for me. Might migrate away from it if you guys incorporate lockscreen notifications for air quality thresholds being reached.
Other than that stuff, I love you guys. Radar is smooth with cool and entertaining, realtime lightning and updates are more realtime than the other like dozen popular free weather apps I have tried.
You guys are unique in being the rare few with; swells, waves, sea temperature, currents, and solar radiation (w/m²).
You guys are unique in being the only ones with; extreme forecast map, aviation map layers, drought map (there are drought maps online but they seem to update every 1-3 months, but yours are every day so much more relevant and useful), soil moisture, moisture anomaly, fire spread, and fuel moisture maps.
Still for now I feel I have a great combination; windy.com app, Emergency by the American Red Cross app, iqair visual app, and the built-in WEA.
