Apple Weather may be better, but DarkSky is gone and it has not included all the features it used to have, such as hourly rain probability for any day.
The cost also went down. DarkSky was $4. I wasn't ever willing to pay for a weather app.
I see hourly rain predictability for today, and for future days there are hourly precipitation charts in inches. I can't imagine that precipitation beyond the current day on an hourly basis has any chance of being accurate.
I think alternative weather apps like DarkSky were incentivized to provide extra information that justifies their existence regardless of accuracy/precision.
E.g., if I make my own weather app and my selling point is that I give you a forecast for every 10 minutes or that my forecast goes out 5 years, I don't have to have any shred of accuracy because it's just a forecast. I was able to sell you my app because you're impressed by the fact that I give you more granular predictions.
I was the same way. Then I broke down and paid the $5. Best app purchase I ever made. One time fee and used it for years. I wish there were more apps like this.
Precipitation probability is the most important thing in a weather app to me.
