@pasmith Hello, I would like to point out that the price for Premium hasn't gone up to stay affordable for a broad public. To answer your question about how Premium got better, for instance, we added 3 completely new features: Satellite archive, extended forecast in the Compare tool, and increased forecast maps' resolution.
Along with this, we moved some of the features to Premium only to thank our subscribers for their fantastic support and offer them something more.
Majority of our features continue to stay free, we are not forcing anyone to purchase Premium.
