Tap ID

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

Geo Calendar & Attendance

The app trusted by the best marchers, directors, and educators in the world.

Why... did they need to update? The original app looked and worked great, had everything in one place, and most importantly worked. Now it's just a buggy mess, can't change dots without desync or "contacting the server", why do you need to contact the server to change a dot nobody else sees? Splitting up the functionality to separate apps certainly was a choice too. Hopefully all these bugs can be fixed by real code, not more prompts to a overworked LLM.

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.

Finally got UDB to re-download and it is working better than ever. Glad it is working now; we have different halftime shows every game so it is important that I have a way to view my drill. I guess I will wait until right before we set drill to open up the shows from here on out so that I don't run into the same issue of needing to change my dot haha
