Backstory: When you're traveling for pleasure or being a nomad working remote, you may run into the chance you need to find the nearest hospital.
The Idea: An app that saves the nearest hospital locations locally and helps you navigate there using gps.
Deep Dive: This would have to be a mobile app that would download the nearest hospital in regions users are traveling. You would store all the information and use GPS to navigate in case of an emergency.
Similar to an earlier idea, you could coordinate with hospitals to find the wait times and alert users that a further hospital may be able to treat you sooner.
Validation: Similar to life alert, this is one of those items you need when least expect it.
Monetization: You could charge a small one time fee, in a basic state, this app is relatively simple. You could make some money at scale.
