Meet the Signul: a smart system that serves as a personal beacon solution to automate things for you. You can use it to create micro-locations and trigger actions when you enter or leave those locations. For instance, you can use this to let your friends know when you are on your way or find out when you are about to leave your valuable items behind.
The Signul is easy to use. Just download its app, turn on a beacon, and choose what you want it to do. It can be used by multiple users. You can also create your own reactions and share them with others. You can use Signul to display alerts, launch apps, open a URL, send a tweet, play a sound, start a call, and more. It needs 2 AA batteries to run. You can support it on Indiegogo.
