Tap ID
Tap ID allows directors to see the performer labels that members have selected.

Multiple students can select a single performer label, so directors can easily see and manage alternates, shadows, and primary performers.

Geo Calendar & Attendance

I can't even open the app without it crashing and saying it has a bug. Someone in my section has the same exact phone as mine and theirs works well, while mine is asking for updates, putting it to deep sleep, or has a bug. Very disappointing.

You still have to delete the app and reinstall for every update to drill. It "downloads" but never loads the updated drill. Rather it shows you the old drill with the new name. This is a consistent issue across all android users that I've talked to. Apple devices do not run into the same issue

Hello, and thank you for your comment and concerns. We did recently push a one time update that did require the redownloading of files, and we apologize if that was disruptive. I'd like to learn more about the other concerns you mentioned. Please reach out to us at support@joinarc.us so we can get to the bottom of this. Thanks!

Takes forever to load and you can't change your dot until it loads. It won't tell you this though and you'll be trying to find a dot that's not yours for ten minutes. Not sure why it does this and UDBapp Pro does not. Horrible tbh
