I shared the idea of an experiment with a group of 6 friends of mine, along with the purpose of the experiment (the same if you downloaded an app that does the same). We share 15 years of our lives together, see each other every two, three weeks, and function pretty well. They all agreed, so I created a simple google pool for anonymous reporting of your mood on a scale from 1 to 10. I sent a reminder for a pool at least once a day. I couldn't see who voted. I knew when the vote was recorded and what was the score. After a week I created a graph displaying the votes through time. I did the same after 1 month.
The first day, the group responded unexpectedly. Six votes ranging from 5 to 10 were recorded. Since everybody saw the votes, they immediatelystarted asking who votes what. Since we know each otherfor a long time, we shared our votes and started discussing why we scored so low/high. It resulted in some deeper conversations and an agreement to meet soon. The next week, scoring and the corresponding conversations continued in the same dynamics. After some time, we realized we cannot solve other people's problems, but continued to meet more often than usual. These meeting were a bit more emotional than the meetings before this. After a month, people returned to their routines, eventually calling each other, rarely checking the pool.
the relations got "deeper", more emotional and uplift-oriented (people feeling better invested energy and time to uplift the people feeling down)
the rate of coffees, meetings and hang-outs increased (people put the friendships before some of their daily/weekly routines)
since it was anonymous, people honestly scored their mood
It's hard to stay anonymous when the scores are low
It's great to be able to report if you feel down, but you still somehow feel that you disrupt the group positive energy
The reporting routine didn't affect people routines and the rate of meetings on a longer run (when everybody were okay, nobody tried to do anything)
The important things to consider
Reminders need to be automatic and adjustable
Scoring function needs to be simple as it can be (screensaver pools, automatic mood detection through browsing history, messages, etc.)
Anonymity when somebody in the group feels down can lead to people engage in finding who is down rather than uplifting the group
To generally uplift the group is not an easy task, since it depends on individual votes
Algorithm that would suggest uplifting stuff to do should not uncover the person who feels down (or it should?)
Maybe the main problem of such an app
If the group members are close to each other, they are more keen on reporting to each other via messages, calls and individual meetings rather than using the anonymous scoring
if the group members are not close to each other, they could feel like not telling the others how they actually feel
It could work nicely in business or project groups, rather than friend circles.
