I am the creator of the application Hafi! I got the idea many years ago while trying to protect my motorcycle from thieves :). I followed a more of a specific hardware approach back then, but now it was time to make use of the existing hardware who most of us have already , our old unused android phones!
Hafi
Your device as an emergency alert system
Like an owl that stays up at night, Hafi is using the sensors of the device in order to listen for changes. Using the built-in sensors, Hafi monitors changes in the environment, and notifies you via a call when these changes are detected.
