Good concept, needs refined – SPAR! - Do it together Review

This app seems like something right up my alley and I was exciting to hear about it. After making an account, I was unable to view any challenges. I just get a white screen when I select “Join a Challenge” on an iPhone X. I’ve tried redownloading 3 times to no avail. Bummer. UPDATE: You must acquire a link to join a challenge. I wish there was a way to find upcoming challenges.
