I see so much potential. I think this is a great app. As sensors develop and move forward, I would expect to see more integration with other systems. In the meantime, to get a five star review for me, you need to start thinking about some user-friendly functions inside the app. For example, I should be able to sort my nodes either by distance, by name, by signal strength, by time of last connect, by anything that is a data field displayed in the node displayed. Given time, I can also think of other user-friendly things. Maybe some functions in the app to fill in the gaps created by the sensors not always picking everything up.
