Does it cost anything to use the app?
You can use the app to find your location, trails and sponsors for free. If you want to track the groomers, a subscription is required for each clubs grooming data.
Why do I have to pay for each club?
50% of your purchase will go back to the club you are subscribing to. The other 50% is used to cover the data tracking costs for each groomer (like a cell phone data plan) as well as app development.
