Great tool for running – Run 10K! Training plan, GPS & Running Tips by Red Rock Apps Review

Helps out a lot when trying to build stamina. Definitely works. However I purchased the app about 2 years ago and now it's asking me for $9 more to remove the ads. I already bought the app. Why do I have to pay more?
