Trying to find meaning in my wife's death by creating an app to help others find lost loved ones. Need advice.

Howdy y'all. I'm not sure if this is the right place to post this. I'm not looking for help in designing an app or coding it (I can do that myself) but I do need advice on a issue that's important to me. <br><br>3 years ago, my wife died of a heart attack in our bedroom. The only other person at home at the time was her 15 year old sister. After trying to do CPR for 45 minutes, our garage door opener stopped working and she was unable to open the garage door to get my wife in the car to drive to the hospital.<br><br>That 45 minutes cost me my beautiful wife and it's something her sister will live with for the rest of her life. She was a medicalclaimed, EMT trained high schooler who buckled under the pressure of watching the love of her life die in front of her. <br><br>I'm trying to find meaning in her death. I'm considering creating an app that lets someone looking for help to scan a QR code in a neighborhood that instantly sends their location to the closest 5 houses. I live in a diverse neighborhood and I don't think I could count on English as a common language for my neighbors. By scanning a QR code, my neighbors watching a person collapse on my front lawn could send me a text message with their location without having to communicate through a shared language. <br><br>I want to do this. I need to do this. I just want to know if there is a flaw with this idea. <br><br>Any advice is appreciated. <br><br>TL;DR: Wife died after I had a garage door opener malfunction and I want to create an app that lets people send medical alert texts without having to speak a shared language.
