I am working on bachelor's thesis with the topic of Actigraphy. My personal topic is primarily focused on classification of free and work days based on accelerometer data in mobile device and/or actigraphy wristband (also just a simple accelerometer), which might be during the time when everyone sits at their home whether they are at school or work or watching tv
Impossible to pull of with even a small precision.

Anyways what do you guys think of platforms such as Mindlamp (BIDMC), Beiwe2 (Tourous) or Mindpax?
