I am a long-ago purchaser of Dark Sky. I find I never use it on my iPhone. Carrot Weather is always superior in both the forecast and Radar. Dark Sky's "it will rain in 5 minutes" was hit or miss.
I live in the mountains, so perhaps, Dark Sky works well in a less difficult environment.
That said, if it disappears tomorrow, I won't miss it.
Carrot is a great app. However, it's expensive and massively overkill for people living in the Bay Area. $40 a year for a warning the 10 times a year it rains is a bit much.
Still, until iPadOS 16 brought a native weather app, Carrot was the best alternative for using the same app across all my devices (Mac, iPhone, iPad, Apple Watch). I'm glad the built in Weather app is sufficiently good that I can drop that subscription.
I sold so many copies of Dark Sky at Little League games. “Huh, it’s going to rain in 7 minutes.” “LOL, that’s awfully exact!” 6:45 later, it starts to sprinkle. “What was that called again?”
You made me question myself if we're looking at the same app... in the "Premium Club" section of the Android Carrot app, I'm reading "Three day free trial, 3.89€ per year after that." This unlocks the Widget, the time machine (past weather reports), removes ads, and saves a kitten. All good things!
It didn't occur to me until they were gone, but I wish I'd asked my roofers what they used. I had my roof replaced a couple years ago in early March. Here in the Puget Sound area by than the winter rain has fallen off, but February and March still average about 6 inches each, so the schedule was "we'll do it when it isn't going to rain".
I got a call one evening saying they'd be over at 8 AM the next day, unless forecasts changed before then. That surprised me because all my weather sources were saying there was a high chance of rain after noon.
They showed up at 8 AM and promptly got to work removing the old roof. I'd expected them to work in sections, taking off the old roof in a section and then putting the new on up to the waterproof underlayment. (The shingles were due to be delivered that evening, so would have to wait until the next day). That way if the rain came earlier than expected they would be able to waterproof whatever section they were on in time.
Nope. They took it all off. They were confident that whoever was doing their forecasting was right that they had enough time to get the whole thing waterproof before the rain started.
As they started putting on the new stuff the clouds were darkening and it sure looked to me like rain was imminent. But they just kept going at the same pace.
As they put the last of the waterproof lining on and started coming off the roof, it started pouring. They packed up, told me they would be back tomorrow at 8 AM to put on the shingles, and left.
You can pick your data source from a list...it also has a nice function that will use your weather station for local conditions within a given radius. That said you need to use a specific brand of weather station for that to work.
