App that automatically monitors 'health' of people based on usage and movements of their mobile phone

Job ID: 32900945

Budget: €3,000 – €5,000 EUR

The purpose of the app is to automatically and remotely monitor people (eg elderly people living alone). Their usage and movements of their mobile phone are considered as ‘signs of life’.
For example, this to prevent that those people will remain lying on the ground unable to reach somebody that can help them. For example, after a stroke or falling on the ground. (My father passed away after a stroke lying on the ground for 16 hours..)

In case no activity (‘sign of life’) is detected for x hours/minutes, then person will get a question (and alarm sound ) if everything is OK. If he doesn’t respond (by touching Green OK button) within y minutes, then max 5 predefined “caregivers” will receive an alarm with a link to Google maps with location of the person (“beloved-one”). The Caregivers use the same app to receive the alarm. One person can be both “Caregiver” and “Beloved-one” through the same app.

Both Android and Apple app should be built.
