Yeah, it was a challenge started around Actifit steps, then kind of extended to steps from any app. The idea is to walk at least 1000*day, so on the first day of the month 1000, on the 10th day of the month 10000 and so on. That was a fun and friendly competition, and for competitive people like me, it could be good motivation to walk more on some days. You can find the details at @poprzeczka, but it's ending unfortunately. Too much work and not enough fun for the organizer, and I can definitely understand.
