Show HN: A fitness tracker for social health

Hi HN - a while ago I became interested in the rising rates of loneliness and mental health issues among young people. I read some really interesting research showing that short in-person interactions, even seemingly trivial ones between strangers, can provide a significant boost to mood and well-being. So, with some others, we built 5 and Go! to help people increase the frequency of their interactions with friends and those around them. While we have gotten some incredibly positive feedback from a small number of users, we have struggled to build a user base and retain users (even those who reported a significant improvement in their mental health after playing for 1 week). Any feedback would be really appreciated. iOS only. We have just started testing a subscription model, but you can get a year for free with this link: https://apps.apple.com/redeem?ctx=offercodes&id=1628590307&code=HACKERNEWS https://apps.apple.com/redeem?ctx=offercodes&id=1628590307&c... Thanks!
