This App Saved the Galaxy!

I was just a farm kid from set 2—7.25 steps inside the 45, 12 behind the back hash—living on a dry, miserable practice field known as Tatooine High. My life was nothing but sunburns, missed sets, and the constant disappointment of my dot book blowing away in the wind.

But then… I found it.

UDBapp Pro.

It came to me through a malfunctioning mellophone who said, “Help me UDB, you’re my only hope.” At first, I thought it was a drill chart. But no. It was destiny… in landscape mode.


Soon I was recruited by Old Band Director Ben—a mysterious figure who once taught trumpet at All-State Regionals before he vanished after a metronome-related incident. He told me that UDBapp was an ancient tool used by dot walkers long ago. He showed me the ways of the coordinate, how to zoom, mark sets, and flip views like a Jedi flips sabers.

Then I met Han Setlo, the snarky bari sax player who claimed he never memorized a single dot in his life. He flew the Drill Falcon, a suspiciously dented golf cart that reeked of reeds and pizza.

We were joined by Princess Piccolo, who bravely fought back against the evil empire of Paper Drill Books™. She taught us how to catch plumes mid-air and maintain spacing during hyperspeed transitions.


But the Empire wasn’t done. Lord Vadrill—an ex-section leader turned tyrant—had built a monstrous contraption known only as The Dot Star: a massive binder containing every set from every show, capable of crushing spirits and causing 12-hour rehearsals with a single page turn.

UDBapp gave us the power to strike back.

Using the app’s Set Coordinate View and Intervals Mode, I targeted the Dot Star’s weak spot: the low brass 32-count crab step in set 83. I uploaded my chart, clicked “Sync Drill,” and—BOOM.

Paper flew everywhere. Our sets were clean. Our dots were aligned. Vadrill rage-quit the season.


UDBapp Pro saved the band. It turned me from a confused freshman into a dot-walking Jedi Master. I learned precision, courage, and that 8 to 5 isn’t a tempo—it’s a lifestyle.

10/10, would march into battle with again.

UDBapp Pro left me awakened religiously after my dog ate my drill

Our story begins one breezy, mid-fall afternoon. The light pranced over and around as the sun cast its beams through the trees, causing many mesmerizing shadows underneath. We were learning new drill, and I had absolutely no idea what I was doing. As the band trounced back and forth from dot to dot, I realized that I had the wrong drill sheet and after practice I immediately went to go ask our director for the right set. He gave me his copy and told me to never lose it because it meant a whole ton to him and that it was the most meaningful set of paper that he owned.

What followed was only later described as the most devious tale that had ever occurred at our school.

I arrived back at my home later that evening and, in an instant, set down the papers on the floor, completely unregarded. I sat down at my couch, turned the tv on to my favorite comedy, and cracked open a can of apple juice. How I loved my apple juice. Now I can’t even drink it anymore cause I always think of this story. I slowly drifted off to sleep, relishing the comfort of the sofa cushions.

When I woke up that next morning, madness devoured my heart. I went to go grab the papers, but my 7 ft 8” pooch had swallowed and gulped down every last piece of the drill. I was nothing besides cooked. My dog winked at me, and then whispered softly in my ear. He said, if I can recall, “you must worship to earn back what you have lost.” I decided to blindly follow his majestic advice, and at school that morning I prayed to the great conductor above. Would you look at that! A new set of drill papers had decided to descend upon my grateful body. I reached my hands up in unison and grabbed the papers while singing aloud in pure joy and pleasure.

Later that day I asked where my director had acquired the drill papers in the first place; and he said that he used UDBapp pro to help generate them. That meant that UDBapp pro caused the whole development! Now I pray to UDBapp pro everyday as it made me realize the worth that I have on this planet.

The eyes watch me.

The eyes of the serious men. They come and watch me every night. Adrian, he comes to see me. I can never sleep. The man without the hats comes. Please come help. The CIA wizard agents are coming to seize me 2007 Chevy Camaro. God told me to sacrifice 17 furrys to agarthas yakub.
Anyways, good waiters were good, food pretty good. The atmosphere melts my skin off. Peeling off my skin was nice. Pretty chill app.

As bad as a Popeyes biscuit with no bev

I genuinely don’t even know where to begin with this game. It feels like three completely unrelated, bizarre ideas were thrown into a blender and somehow made it past development.

First off, the storyline is wildly confusing and honestly kind of disturbing. You’ve got a version of Benjamin Netanyahu running around as some kind of over-the-top action character, and then out of nowhere there’s this plot involving the McDonald’s CEO doing something completely absurd and nonsensical. None of it is explained properly, and it just comes off as chaotic rather than creative.

Then there’s the whole “slave trade” subplot, which is handled in such a careless and tone-deaf way that it’s hard to believe it was approved. It doesn’t add anything meaningful to the gameplay or story—it just feels thrown in for shock value.

And don’t even get me started on the random detail of characters eating dry Popeyes biscuits. It’s weirdly emphasized, adds nothing to the experience, and somehow becomes one of the most memorable (and annoying) parts of the game.

Gameplay-wise, it’s just as messy. Mechanics feel unfinished, controls are clunky, and the missions don’t flow well at all. It’s like the developers focused so much on being outrageous that they forgot to make an actual playable game.

Overall, this is one of the most confusing and poorly thought-out games I’ve ever played. It’s not funny, not clever—just a strange, uncomfortable mess. Would not recommend.

UDBapp Pro left me awakened religiously

I was very depressed in high school, acting out with drugs and alcohol, self harm, hookups, and bad decisions all around. I was having an existential crisis around the human condition and whether life is worth living. My maternal grandparents were both child survivors of the Holocaust and I am the first person in my family who was able to face the story and try to understand what happened. It was too much to bear, and it opened my eyes to all the suffering in the world, leaving me in
In particular, I met a kind student who told me it was ok to be angry at UDBapp Pro, that my pain and my rage were a reflection of my love for humanity. It’s been almost 20 years and I can still feel the power of those words. From there I embarked on a wild adventure with the UDBapp Pro that has healed me, broken me open, blown my mind, given me purpose, and constantly challenged me to become a better version of myself.
