There's no doubt that mobile phones can be very useful in the case of an accident or an emergency... provided that we can quickly access the right numbers to ask for help or notify the SOS or security services required. Google has thought about this idea and come up with Personal Safety for Pixel phones.
A shortcut to selected contacts and security numbers
This application allows us to select from our list of contacts those numbers that can help us out. Thus, in the event of an emergency or need, we can quickly contact them or other security, medical or SOS services, either by calling them or messaging them (providing our location while we're at it).
The application allows us to configure a user profile to include details that may be important in the case of a medical need, such as blood type or any other medical information which could be significant in the case of first aid.
And we all usually have our phone locked by means of a PIN, pattern or fingerprint, we can establish open access to the app from our device's lock screen so that anyone can quickly send an alert if we weren't capable of doing so ourselves.
