Justice for sloppytip123

Sloppy tip was my best friend until he was taken away from me after leaving a review on this app. Please bring my goat back. Yours truly- sloppytip123s bsf

Justice for SloppyTip123

After I heard about the Sloppytip123 insident, I was flabbergasted at the audacity of such a person to do such a thing. Sloppytip123 has only been nice and kind their whole like and here is someone dragging them down over nothing. I hope they one day willl see themselves in SloppyTip123s shoes and know what its like to be a SloppyTip. They say “Waiter! Waiter! My steak is too juicy! My lobster is too Buttery! But did SloppyTip123 complain? No. To have such pride to think you can do such a thing to the SloppyTip family is unheard of. They say, “We are Chasing Utopia! Rising Above the Noise! We’ve seen it In A New Light!” but clearly they havnt. I hope something can be learned here, and someone can give justice to SloppyTip123, for we are only At The Threshhold for the justice that should be givin.

Took a great app, made it horrible

As a marching band student for many years, I’ve used plenty of apps for drill. Until recently, I’d been using the regular UDB app (orange), and it was pretty good, easy to use. I can’t even begin to express my disappointment with this app. The count-circle mechanism is awful, and several basic features are locked behind paywalls. Instead of easily being able to see the notes and measures that go with the drill you’re watching, you have to change over 2 pages, which ruins any sort of learning continuity. The counts are not even really timed either the movement of dots either. A bunch of new, flashy, and useless settings doesn’t make up for the basic lack of functionality this app now holds. Thank you for making the season of several marching bands twice as difficult.

Update to my original review

I originally hated this new UDB, but after using it for a little longer, it’s not too bad. The UI is a lot different and was confusing at first but now I actually like it over the old UDB. Overall the Arc version of UDB is way better than the Arc version of Beam and I don’t mind it.

New UI feels like a modernized downgrade

The old app had much bigger buttons and was much more intuitive, on top of the field area being much bigger due to the lack of a giant useless circle. Half the time I accidentally hit the middle button instead of the dial to swipe thru pages. I miss the ability to set my own dot as a dot and everyone else as a letter and I find the new UI very clunky.
