I love the idea behind this app but unfortunately it currently has a large number of bugs the need to be worked out. First, every time you exit the app you have to completely force close it or it will no longer receive updates from the sensors. Second, there is no way to completely delete previously used sensors. You can tell it to delete them but they simply repopulate once you exit the app and return. I currently have multiple (4) readings for a single sensor. Third, the list of supported sensors is dismal at best. I could go on but I think youve got the idea. If the developers dedicate themselves to finding and fixing all the problems this will eventually be hands down my favourite app.
