The app that lets you spread kindness through a cup of coffee. With Nack, in just a few simple clicks you can send a cup of coffee to a colleague, a neighbor or even a friend who is thousands of miles away. It's what we call, Random Acts of Coffee. Occasionally companies may also sponsor coffee - one for you and one for you to send a friend. So…next time you are in a cafe, or anywhere for that matter, use Nack to receive and send a little kindness- you’ll be surprised how good it feels.
