Great weather app
This is a really convenient way to keep track of the local weather. I have found it much more accurate than the weather app that comes on my phone. And it will notify me when rain is coming, which gives me time to get my tools put away at work! This has been really helpful I would absolutely recommend
Filled the DarkSky void
I’ve been looking for an app similar to DarkSky ever since Apple ruined it and GrayCloud is that and more! The rain prediction is the most accurate that I’ve found and I think I’ve tried every weather app there is. The devs seem to never stopbuilding too. Excited to have stumbled upon this, highly recommend!
Dark Sky revival …
…and it almost may be even better. Such a simple interface backed with a wealth of data and information that is easy to get to. With the source data coming from the NWS it’s also super accurate. The developer is very receptive and active as well. Good stuff.
Clean, intuitive weather app
Really enjoy the UI of GrayCloud. If you enjoyed Dark Sky, this is a great alternative.
great design, accurate weather
I’ve always just used the Apple Maps app, but I like this one better
Simple and effective
Clean, simple, easy. Accurate weather without all the clutter and noise from other various weather apps! Highly recommend!
