User reviews

Stupid app

Once again writing a review, my dot is gone. Idk why drill is messed up but my dot is gone from the selector, it is on the drill. This is genuinely broken.

Thank You

For my first year using it, it has been super helpful for marching band but I noticed that sometimes one of my movements won’t update at all and I’ve tried to redownload it. Other than that, it has been super helpful so kudos to the devs.

Great App… when it works

Using this app has been great for HS marching band, but it’s also been a tremendous headache with students and staff being logged out of the app with no way back in, performance issues, freezing, etc. the app is a huge step forward but I cannot recommend this app in its current state to anyone.

Help it doesn’t open or work or load

When I open the app it doesn’t work for me, I deleted it, I restarted my phone, i did everything it still doesn’t worked,the loading screen takes forever to load

This is serviceable but I miss UDBapp Pro

I’ve got some qualms with the UI, overall I feel like it’s a step down from what we had with UDBapp pro, I feel that much of the functionality doesn’t need to be hidden behind menus (specifically drill switching), and there have been several issues where drill won’t display correct spacing from sidelines which can mess some things up. I’ve also had issues with randomly being unassigned from my dot which is mildly inconvenient.
