There is something similar to your idea: Apple Research Kit http://www.apple.com/ca/researchkit/, that allowd medical researchers to organize studies and track participants. How is your platform different from it?
Two difference between Ethica and ResearchKit: 1. ResearchKit being from Apple, only works on iOS, while we are trying to have a tool for data collection from any platform, Android, iOS, smartwatch, etc. 2. ResearchKit is more of an API which can simplify coding of a research app, but still requires knowledge on iOS programming to get the app done, and then you need to deal with all other pieces you need to have an end-to-end product, the server, the back-end, data storage, etc. For many, this is way too much technical work to be able to use ResearchKit.
Overall, it's nice to see there are other groups working on this idea as well. It can attract more attention to this need.
