The purpose of Acoach is simplifying the process of developing business online, by reducing the time spent on managing clients by around 25%. Our job involved implementing many features which allow, among other things, for receiving and browsing coaching applications from prospects, generating clients' logins and accounts, as well as handling and tracking clients' payments. Thanks to this application, coaches are able to distribute training plans to their clients, collect their comprehensive history, and moreover, create their progress reports, which can be browsed by both coaches and clients. For subscription the systems Stripe and Clickbank were employed. This app allows for eliminating mail contact and showing all the necessary data in one easily accessible place.
