I worked for an online "weight loss" coaching programme and was really disappointed how it worked: People pay monthly subscription fees just to get an automatically created food plan and some analysis of their food protocols - no individual tipps how they could live more healthy. But individual tipps and helping tools are essential for a really effective coaching. This is what I want now: an online health coaching which is really helpful to the user.
The programme should be modern, multi-medial, easy to use and playful - but serious and reliable. I want to create a programme which offers interesting information and game-like taks and which uses user input of any kind to filter those informations and tasks in order to show just really fitting ones to the user.
