Make an app called HighLe (HighLife)

I would like to make an app called HighLe meaning High life. The meaning of this app does not imply high life of getting drunk but the feeling of achievements an individual feels after learning something. 

  1. This app will allow users to evaluate themselves where they currently are based on the goes they set years ago.
  2. Users will need to be authenticated before setting goals. 
  3. When another user achieves a goal, all users are notified. More like LinkedIn does.
  4. This app will be simple,  no clutter and well thought to run fast.
  5. The idea is to keep track of life goals.
