Many people in the world equate "Colgate" with tooth paste and for sure they all know how to use it. No explanation needed. 

Airtime Queen is just that - a colgate app.  

My definition: 

A colgate app is a powerful Web3 dApp with a TradApp/ Web2 UI, familiar terminology and familiar access & authentication methods. Colgate apps can be used out of the box by any consumer without any pre-existing crypto knowledge or tooling. 

Refresher: Airtime Queen is the revolutionary app that allows prepaid users to buy airtime, get rewards, and, most importantly, access airtime credit at no cost.
