Doesn't display any info for Floyd county – Elevate Parcel Review

Just installed this app in iPhone 6 with latest iOS. The app launches and lets you go to the county above but when you try to get information it says you need a subscription. Cannot find any information on subscribing like how, where, how much, etc so the app is kinda worthless as is! It looks promising though
