Panic Button for the Smartphone Age
Witness uses every single feature your iPhone can provide to keep you safe in an emergency
How it works
You only need one touch to activate witness. As soon as you launch it, it will call and text all your emergency contacts.
Witness will record your location, camera and microphone and stream it over cellular and wifi to your emergency contacts in real time. If wifi or cellular is not available, it will record everything on the device till the battery runs our or all storage fills up. It records in 10 second chunks so your data is always there.
