Feeling safe

Sometimes you are not as clearheaded as you may think, especially when adrenalin rushes through your blood. Knowing you can inform someone by just pressing a button to inform them about your whereabouts is reassuring and will reduce the stress.


Existing solutions

Many companies provide tracking devices and platforms to list a person as emergency contact. These tools and platforms are often too limited. They only let you list one contact, don't let you adjust the channel where you will receive a notification and you don't even know what will happen with your data. There is no real standard since everyone provides their own solution.
