Many thanks for ActivitiyWatch! I heard about it for the first time today and have already tried many approaches in this area, because I am very in QS (in all areas). Someone in the Exist.io forum mentioned this project.
In this context I also “stumbled” over the topic of emotion tracking and share the opinion that Gyroscope has a very smart approach in this respect, which is providing much more (approach, UX) than many other approaches.
Nevertheless, I find it insufficient and unfortunately there is nothing better that forced me to design an approach myself. The whole thing is actually only in the “private pre-alpha” stage and will be tested by about 10 people. It is also still very nerdy, but is further developed as a protype, in order to convert it later into another form.
As an Excel approach (I know this is rather unusual prototyping…) it also ensures 100% data privacy, which is very important to me.
Maybe you are interested in this concept and we should have a chat
