Not a new concept. Many have tried and failed. Even though the social cause is clear and many people will say great idea, very few will use it if their life is on the line. And even less will pay for it unless it's bundled with some sort of home care service/monitoring. The 1st point is actually a big liability problem. If your life is at risk will you make a 911 call (which even works without data coverage) or trust an app that you have not started in a while to work as expected? And you must have data for it to work too right. Apps need consistent updates to fix bugs and when a OS update breaks it, you are putting people at risk. Too much of a risk to take to rely on an app to save your life. The 2nd point, is whether you will end up having a business. You have a business when someone pays for your product/service. Until then it is not a business. Who will pay for this luxury of a better 911 and why do they really need it when 911 is free and more reliable? If the emergency is not 911 serious level than what role does the app play? Hope these questions help you flesh your thinking around this space/product. Just because you build it don't mean they will come ;-)
