So apple owns dark sky and it dies 1/1/23 update 10/25

So if apple owns dark sky and they are killing the app 1/1/23 is this still going to be here??

Update 10:2024:
Developer redid the app, but it is a severely denuded version of Apple weather. It lacks pretty much everything that the Apple stock app will give you. It’s lackluster it seems more like a widget than an app.

Hello! After some much-needed repairs, I'm excited to share that the latest version of Blue Days (V7.0) is now live and fully functional! This update comes with no ads and no subscription required. If you still see Blue Days under your App Store subscriptions, feel free to cancel it—you’ll still be able to enjoy the app. I’d love to hear your feedback once you’ve had a chance to try out the new version! New features will continue to be added in the future.

Terrible app

I tried this after Dark Sky went away. Thank you Apple for dumping the best weather app out there. Anyway, paid for this, reloaded at least 5x. And a couple of yrs later it still won’t work.

Terrible app

I tried this right after Dark Sky went away. It was terrible. We are a year or so down the line, so I thought I’d give it another shot. Nope. ‘network error’ is constant every time I open the app. Or it tells me I’m offline. Why did you take something that worked, messed with it and now nothing works?

Why is this on the App Store still

When Dark Sky went off the market, Blue Days quit working since it used Dark Sky data. Why is this app still on the App Store. IT DOES NOT WORK ANY MORE!! Don’t buy this!!!

Offline?? Really??

I can’t even get the app to open. Keeps telling me I’m offline. A surprise because I searched for the app, downloaded the app and now am complaining about the app with full internet. I tried clicking the support button - but that goes to the developer’s Twitter/X account. So I give up. Delete.

Too bad it doesn’t work

I downloaded the app and loved the layout. I was happy to pay the $2 to help the developer out for what I thought was a great simple app. Too bad it quit working for me. Is it unfair that I feel cheated? I know it was only $2, but to me it’s the principal.

App crashes every time

App crashes ever time it’s opened, and cannot connect to the network to get weather.

Useful WHEN it decides to work

Paid the subscription, worked as expected for exactly two weeks—and then it didn’t. App has been “offline” for nearly a month now, and apparently no way to get a hold of support for a fix. I’ve tried deleting/reloading app, but still nothing. Perhaps this review will be seen by support for either a fix or a refund.

Not working any more

This app has not worked on any of my devices for almost a month. It keeps saying Network Error. If it worked I would give it five stars.

Stopped working

This app stopped working one day because it couldn’t find the internet, and has never worked since. I get a message that it is offline and to check my internet. I have no trouble with any other app finding the internet

No longer works

I loved this app and signed up for a paid subscription. But a few days ago it stopped working. It keeps telling me that it’s offline and can’t get a forecast. It CAN get an ad however. I uninstalled and reinstalled several times but it’s still not working. Very disappointed. And the support link takes me to twitter which I don’t use.

Nice graphics, poor localisation

I really like the presentation graphics, well thought out and displayed. However, although it shows my correct location, the weather data seems off and the lunar phases definitely are wrong. For example, we have a full moon tomorrow (according to the Royal Observatory) and the app is telling me that the current phase is waning.
