I’m gonna ask. *2024-07-01* Look, guys. It’s a good little app. Can we please have the option to change from centigrade to Fahrenheit and change location to see what the weather will be like where we are traveling to before we get there? It’s not too much to ask is it? ### 3/5 — Crashing Repeatedly after Launching *2023-09-25* Not sure what the deal is but this app has been crashing constantly. I open it on my device and it crashes within 30 seconds or less of launch. Used to crash once to the Home Screen and work after a second launch, but now it’s crashing all the time. Not worth the time to check it if I have to deal with constant crashing. I’m giving it three stars for now. If it corrects itself I will raise the review accordingly. If it continues like this I will lower it. **Developer response:** A new version of Blue is now available on the App Store, and the issue is now fixed! Please accept this weather joke as our apology: What does a cloud wear under his raincoat? (scroll down) Thunderwear! ### 4/5 — Applicazione fantastica *2023-06-16, version 1.5.2* 4 stelle perché Manca l’umidità. ### 2/5 — Forecast *2020-11-19* There used to be a two week forecast. Why did you take it away? Also, the location should be able to be changed, people want to see the weather at places where they will go, not always where they are. Used to be a good app, now not so much. ### 5/5 — My favorite weather app *2020-08-19, version 1.5* No other app displays the weather this simply! fastest way to get a feel for the weather possibly my favorite app of all time! ### 3/5 — Uhhh... *2020-04-03* This app is -ok-. It is super simple -er too simple. It has a lack of customizing and I really wish you could change the location or maybe switch the weather data that’s all though. It is a good app, just way too simple— ### 1/5 — No updates ..inaccurate weather...dead app? *2020-02-26* I have been a strong proponent of this app for several years now and have found it to be one of the most simplistic yet accurate and useful tools of all my apps. You wanna know the temp right now you got it, you wanna know in 3 hours what to expect you got that too, you want to track the start and stop times of some oncoming weather thing and this app was spot on accurate down to within about 10 minutes no joke! I loved it but the last two weather events about to roll in my area, and I pull out my most trusted weather app to find out then”real” story, it tells me no bad weather just a couple hours of light flurries, so the weatherman and everyone are wrong again...within minutes it started to dump snow and the app had it clear or light flurries. I ignored it as a glitch but today similar thing, schools are closing as a proactive measure and when looking at the app, for a few hours they show a light chance of light flurries then clear! Inaccurate weather reports are about as good as a sandbox in the desert! Seems there is no support or updates so to me it’s a delete, with a warning to others, I wouldn’t trust this application if I were you! Am deleting now! ### 3/5 — Lack of Customisation *2018-07-19* The app is great: easy to use and very simplistic. The problem is that it is perhaps too simplistic. I, personally, would like a little more freedom is terms of customisation like being able to choose the hue that corresponds to the temperature or even something as simple as being able to choose the unit of measurement, for example. The app is exclusively in Fahrenheit, which I think is something that should be changeable. ### 5/5 — Quality app *2018-05-06* Blue does everything I need from a weather app. The visual interface is really pleasing. The colors make it really easy and quick to see what the weather trends are going to be. Also, it’s nice to have Dark Sky’s information without paying for that app! ## Frequently asked questions about Blue ### What does the app do?
