There is a mobile application ExamMobile: PMP.
Its intention is to get people prepared for PMP (Project Management Professional) exam. Application for test. Questions database prepared by certified experts.
It was posted in AppStore and Play Store (iOS & Android) 1,5-2 months ago, but sales are not so good as I wanted.
So I would like to have someone to join the team as a person responsible for increased amount of downloads and sales. I expect that you will write a high-level steps (or deliverables) which you intend to aim as a path to application success. I will pay by deliverable. Approved\Implemented\Payed.
I think that most important countries will be: USA, Russia, India, Egypt, but we can discuss that later.
