Bad Update

I NEVER write reviews, but for this App I feel its necessary. Last update is horrible. UI is MUCH worse than previous version, and the developer decided it was a good idea to charge 0.99/year to remove ads. Previously it was just a one time charge. Im deleting this App from my phone, with the hope that theres something like the old China Air Quality App out there.
