alt Hacker NewsI used the Dark Sky app since it came out in 2012. I used to consistently get notifications about precipitation with Dark Sky, that were consistently accurate. The Apple weather application seems less motivated to send me notifications with any sort of regularity. I almost never get them now, even with fresh iOS installs. I haven't moved either.
And just anecdotally, Dark Sky was a delight to use. Apple Maps makes it a chore to extract the same utility from their app.
OK, notifications aren't the same as accuracy though. Neither is delight. I'm just talking about the supposed drop in accuracy that I just don't see.
(And Apple notifications are a mess generally. I constantly have notifications for something yesterday only show up today. I'm not sure that has anything to do with Weather specifically, their whole notification priority system is borked.)
