I asked for honest feedback for my app https://everydaycheck.com on a couple of subreddits where people are trying to get disciplined and improve themselves. Since it was my personal goal too I could easily relate and that brought a lot of signups, great feedback and most importantly, engaged users!
never saw the old Lift app but it is not the first time that someone names it when seeing everydaycheck :p
be assured this won't turn into a coaching marketplace. My goal is to charge a symbolic yearly fee and keep it as it is. After all, it does one thing and it does it right!
