You continuously have login screens with no way anyone can register or subscribe. No wonder you have few or no ratings because there is no way to use this app to rate it! Is is because you charge alot for your service and are keeping it a secret? If you are charging $ for info that can be free elsewhere, shame shame shame! **Developer response:** Hello, and we apologize for only just now noticing your review. This app is a free COMPANION app to our SiteWarn service. It does not work by itself.
