This was a fine app until ads began covering the Forecast, my tab of choice. So I’ll be deleting.

Too hard to decipher

Might be great for somebody who knows how to read pressure charts, but I do not. There is no key or any kind of guide to explain how to use the app or what any of the data means for those of us who are sensitive to pressure changes, except for a “caution” and “warning” highlighted area, and even those didn’t have any more info. There’s also no way to change your location to anything but your current one from what I could tell, so unhelpful for planning trips. I switched to Pressure Pal and knew within 30 seconds I like that app way better.

Helpful

Hi. I just wanted to let you know I find your app helpful. I have chronic daily migraines and the majority of them are weather related. But I notice in your app you only use the words “caution” and “danger” when the pressure is expected to drop, not when it’s supposed to rise. That’s when my headache symptoms begin. Thought you might consider adding some additional warnings for people who have those migraines. Thanks!
