Ripple Notes is the first app that allows you to follow the chain reaction of kindness cards that you pass from person to person. As the cards get passed, the users scan the QR code on back which allows the app to geo-track the journey of each card. The journeys of all the cards can be seen in Google maps inside the app. This idea reinforces the notion that a simple gesture of kindness can impact hundreds of people around the world and allows participants to share their gratitude and appreciation with one another.
