I took at the ‘Fitocracy’ app for ideas on how to motivate the team members and draw users in. Before signing up to this app it gives you an insight into how the app works and the benefits of using it in a motivational manner.
I feel that this insight into the app before you sign up is a great aspect.
Furthermore the idea of working with a coach on a daily basis to keep motivated and on track is a great selling point of this app. This allows for a personal user experience.
