So here's my honest take on Ouranos: Clear Sky Forecast. I've tested a bunch of weather and astronomy apps, and this one's pretty solid. The forecasting features are super useful if you're into stargazing, whether you're a beginner or a pro. And lets you know exactly when the conditions will be ideal. The personalized tips are a nice touch too. Only real downside is the UI is a bit outdated, but it's functional. Overall, if you're into the night sky, this is a great app to have in your arsenal.

Been using Ouranos: Clear Sky Forecast for a couple months now. It’s basically an app that tells you the best times to go stargazing. Pretty solid if you’re into astronomy and astrophotography.

Here’s what you do: You can check the forecast for cloud cover, moon phases, meteor showers, and all that stuff. There’s also personalized recommendations for the optimal stargazing nights. And it even has tips for beginners – took me a while to figure some of that out but it’s useful.

Look, if you’re into stargazing and want to up your game, you’ll probably like this. It’s not perfect – the UI can be a bit clunky at times – but overall it does the job. Worth checking out if you want to make sure you don’t miss any clear sky nights.
