Platform Justifications


Using a mobile app instead of a desktop app is critical to making a good solution.

  • A mobile app would allow people to help out on the go: wherever they are.
  • It also expands the amount of users who could have the app, especially in developing countries, where lots of people don’t have a desktop, but many people have a smartphone.
  • Using a smartphone also allows the good Samaritan to be guided directly to the person in distress.
  • Additionally, the phone can give updated information as the good Samaritan is in transit.

Given all these factors, we can see that a smartphone app is a better fit for this problem.


Using a smartwatch instead of a smartphone provides a few key improvements.

  • It allows for quicker response time. These few seconds it takes to pull out your smartphone can be the difference to save a life. The timing of EMS is critical and the app is trying to shave off minutes and seconds from our current EMS response times so utilizing the speed of a smartwatch response is worth it.
  • Using a smartwatch has a lower likelihood of a responder missing the notification. Since a watch is almost always on your wrist, the notifications can be more assured of reaching their intended targets. With a phone, sometimes people don’t feel or hear them in their pockets/purses.
  • The app allows the good Samaritan to have their hands free as they’re updated with information. Having to hold a phone in order to read or hear instructions can limit their ability to help out in a situation.

With all these factors under consideration, we think a smartwatch app is appropriate in this situation. There would certainly be a phone app as well, because smartwatch adoption is low at this time, but for those that have a smartwatch: all those seconds add up and could save many lives.
