I've been using Today Weather on Android ever since Dark Sky was killed off there. It looks nice, lots of different data sources, and the $7 lifetime
Premium Version is a good price.
fwiw, I paid for a lifetime sub to eHD Weather (by Elecont) ... back in 2013 and still use it. Moreover, the dev still responds to emails within a couple hours. If I can get 10 years of use out of an app for $5, that's excellent value!
I presume you mean the $7 "For as long as the developer feels like it" Premium Version.
