Loads fast on an iPad

This app works well and works quickly on my iPad Air. Other weather apps I’ve tried take a substantially long time and/or hang. Sometimes other apps are filled with ads to the point of harming functionality. Thankfully this app does not have that problem.

Best replacement for Weather.com that I have found!

Easy to use and reliable. I like the hour by hour and day by day numerical probabilities for precipitation.

Not so accurate

It will be raining and this app always says it’s foggy or cloudy. I don’t get it.

1 weather rules

Favorite weather app ever! I had it on Android, and now on iOS. Love it.




1Weather might just be the best all around weather app that I’ve tried. From my user experience 1Weather is quite accurate with both short term and extended forecasts. Your mileage may differ in your location, I do not know. The app is not updated very often and it has been a good while since the last update. I hope that the developer does not lose interest in this app because it is one of the better ones.

Something changed?

I’m not sure what happened. This app used to be the best weather app and now it is complete garbage. It is consistently WAY off and does match up with any other weather apps. It routinely tells me the wrong CURRENT temperature let alone it’s awful predictions. Only useful for the radar, otherwise stay away.

No iPhone X screen support

You have the nerve to ask for 1.99 to update to Pro and you still don’t have support for the iPhoneX screen? What a joke. I’d have no problem with a paid version if you guys actually did something worth buying.

Good Radar But That's It
Taos Artist

The current temperature and next week's forecast is a total joke but radar is great. Local temp is usually off by +-20° and this is the only weather info that constantly forecasts rain for next week when no one else does. There doesn't seem to be an app that comes close to the sadly now defunct Storm App.


Extremely easy to operate and use. I wish it showing the heat index. Other then that, it’s perfect!
