This app worked really well for tracking my friend. Never used it before 2024 so can't speak to any previous issues in prior years. But for seeing my friend almost exactly where he was on the course and planning to meet at certain spots, worked great. Real time map feature was perfect. Thank you! Also, he didn't need the app as a runner but it differentiates between runner or spectator, not sure the exact differences but thought I'd mention that.

When will this app be updated?

A lot of the functions are fantastic but I couldn't give this a higher rating because even though I turned notifications off my phone would all the sudden start reading out random notifications and I couldn't stop them. It would say things like "Don't forget to get icy Hot at tent 13" or "Good luck to all of our runners today".

Mildly helpful for seeing the route I guess...wasn't even available until a few days before, lagged a bunch with tracking our runner, and only a few CTA stations nearby were marked, so I had to use several apps at once to help me figure out where to go (really annoying when you're trying to track quickly in a race). When you zoom in on the map, it doesn't let you go far enough to see street names quite often. Thankfully our runner had downloaded a phone tracker app, which was much more accurate!

This app is useless. It constantly requests permission to access your camera and storage without explaining why it's needed, and even after you grant those permissions, you gain zero functionality. The app doesn't let you watch the event (or even visualize the positions of runners). I was able to look up a friend who's participating, but there was zero data about how they were doing. To add insult to injury, the app shouts ads at you in a robotic voice. Tata Consulting failed miserably.
