I got DarkSkyWeather years ago when I was getting rained on and my two weather apps were telling me that it wasn’t raining and that there was a zero percent chance of rain all day.
It has rarely let me down over the years. I’ve always used it with the Apple Watch and the notifications are excellent. Another thing I like is that it breaks down the hourly forecast for the entire seven day forecast, something other services provide in website form but I’ve never seen on a subscriptionfree app. While dark sky is very good in the short run, I don’t trust it much a few days out, but the hourly stuff is still useful. I have apps that say 100% chance of rain on Saturday and then I check dark sky and it says that that 100% chance is at 4 am but no chance in the afternoon. That detail is very nice to have.
A request to the developer: please allow customization for the different aspects of the forecast. I live in Florida, so right now, I want heat index, chance of rain, and UV index. Nothing else is relevant for 95% of the time I open DarkSkyWeather . But instead, it goes temperature, heat index, precipitation probability, precipitation rate, wind speed, wind gust, humidity, dew point, then, finally, UV index.
