The show all and open all features don’t work for me, Field notes are hard to draw when laggy, the layout is kinds confusing, and the app feels laggier. Overall it’s not bad. But it could be better. **Developer response:** Stay tuned for an exciting update coming out this week that addresses many of the issues currently present for older devices! ### 3/5 — Play animation won’t work *2026-08-14* I like the app and how it works but when I press the play triangle on the page it just switches to the counts and doesn’t play the actual music or the dots move ### 3/5 — Good but fails to let me update drill *2026-08-13* This is our first year using this app and it works really well but we got new drill for band and most people can see the updated drill but me and some others can’t update it and it’s real frustrating because the automatic update is on and I’ve tried to do it manually but nothing shows I really hope they fix this bug soon because I got drill to put down soon **Developer response:** Stay tuned for this week's update that will address this refresh issue you're running into! If you notice any other issues, please reach out to us at support@joinarc.us and we'll dive in right away! ### 2/5 — Animation and Music error *2026-08-13* For some reason whenever i click the play button to see where my dot moves or to hear the music nothing happpens it just stays in one page. Please fix this bug i really need it so i can continue marching my show please and thanks. **Developer response:** Stay tuned for this week's update that will address this refresh issue you're running into! If you notice any other issues, please reach out to us at support@joinarc.us and we'll dive in right away! ### 2/5 — Annoying glitch *2026-08-01* When I click the play button to see the drill move around, it just switches from page mode to count mode and the drill stays frozen? I looked all throughout the setting in the app and cannot find a solution. Because of this I cannot hear the shows music and I cannot see my dot move around the field. **Developer response:** Hello! Please check to see if there's an available update as we've just pushed out a new build this morning! If you run into anything else, please chat in on our website or email us at support@joinarc.us ### 4/5 — Tronald Dump’s Thoughts *2026-08-01* The app functions very well, I long it very much. You know I am thinking of giving it a Nobel Peace prize it is so good, no one has seen anything like it. They also gave me a tummy rub, it was very nice. My name is Tronald Dump and I approve this message ### 4/5 — Apple Watch support *2026-07-28* It would be nice if instead of it saying what page you’re on on the Apple Watch display, it would say your dot, out if you guys could have an Apple Watch supported app, that would be even better ### 2/5 — honestly the drills printed on paper is easier😭 *2026-07-24* We were just looking at our coordinates on paper before we downloaded the app and it was honestly better…sloppytip123 is so right🥹 **Developer response:** Sorry to hear this has been your experience so far. Our brand new UI allows you to tap on the coordinate on the top of the screen and see a dropdown of all your coordinate information but also includes crossing count, step size, measure numbers, etc. In addition to the coordinate information, tapping play on the right side shows you the animation, plays the audio, and displays the path information! Feel free to chat in on our website or email us at support@joinarc.us and we'd be happy to set up a demo walkthrough to show you how to maximize the drill learning experience! ### 1/5 — Holy Downgrade *2026-07-24* The old app was a lot better and cleaner. This is unacceptably difficult and the UI does not work a lot of the time. I buy UDB to save save and this is costing me more time and the price just went up! Bring back the old program! I am debating cancelling my subscription for my program and going back to printing paper packets. It’s that bad. **Developer response:** Sorry to hear you've had an issue with the latest UI. Please chat in on our website or email us at support@joinarc.us to let us know what you're running into. We're pushing out an exciting update in the coming weeks that takes full advantage of the new UI. Also, we love hearing from our users so please share your thoughts with us and we'll be very happy to get a member of our team on a call with you to see how we can make the app even stronger for you and your program! ### 1/5 — Regarding sloppytip123 *2026-07-22* I have to say, I am a big fan of the reviews left by my favorite reviewer; sloppytip123. They are insightful, especially when they mentioned that this app caused their eyes to irritate and subsequently water, which they worded as crying. I too faced this phenomenon after downloading and first applying the UDBapp, however I faced tears of hardships instead of tears of joy. The app has a new UI, which, simply put, is absolutely atrocious, and I struggle greatly with the knowledge that I now must use this app as opposed to its predecessor. Again, I love sloppytip123, but instead of leaving a five star review like my idol happened to do, I must instead give my rating a one star due to the reasons previously mentioned. **Developer response:** Stay tuned for an exciting update that increases functionality with the new UI, including the Overview Screen in just a few weeks! Feel free to reach out to us at joinarc.us and share any thoughts. We're always excited to hear from our users to see how we can make our apps more user friendly! ### 3/5 — Needs additional settings *2026-07-22* The wheel icons are too close together, causing mis-clicks of going to the Home Screen/playing/changing. Please also allow haptics to feel each count when clicking +/- on the gold wheel. Allow “auto update” setting for students. **Developer response:** Thank you for the feedback! We are adding these considerations to our list and would be excited to hear about any other ideas that you have. Please chat in on our website or email us at support@joinarc.us. ## Most critical reviews (10 lowest-rated) ### 1/5 — UDB is kinda alright I suppose... *2026-08-17* My brother and I hate this app so much that we came up with a list of adjectives to describe it. 1. Sloppy 2. Tippy 3. Slimy 4. Sticky 5. Round 6. Has balls 7. Has dots 8. Rhythmic 9. Unenjoyable 10. Needs internet (why???) 11. Long (for good boys) 12. Short (for bad boys) 13. Plump 14. White all over screen 15. Maybe choke 16. Horrible 17. Beige 18. Bland 19. Sweet 20. Hairy 21. Has black streaks 22. Pulpy 23. Diddy approved 24. Oily 25. School appropiate 26. Popular 27. Loooved by director ### 1/5 — Hi bestie *2026-08-17* My bestie hates this app ### 1/5 — Eyesore for Drill Reading *2026-08-05* The old app worked just fine. Everything is so dense on the screen even with small bands. I haven’t been able to figure out how to get both dots AND letter/number on the drill page at the same time. It is an over built app in the areas that doesn’t seem to be very beneficial to band programs compared to the old app. **Developer response:** Hi! It sounds like your drill writer can address the symbol/label issue you're talking about where they would put the section/number under each dot which is our preferred method of displaying the dot! ### 1/5 — App won’t load *2026-07-31* Every time I load the app, it will not load for me and will just stay on the Home Screen. I’ve tried deleting it or resetting my phone, even updating it. But I think it’s just an app issue now. **Developer response:** I'm sorry to hear you're running into this. It sounds like it's related to a firewall or settings issue. Can you chat in on our website or email us at support@joinarc.us and we'll help you get it sorted out! ### 1/5 — Another Horrible Update Once Again *2026-07-29* I used to really enjoy the previous UDB as it provided an excellent place for all of your drill to be read in an organized fashion, allowing you to see the big picture and shapes of the sets. What this new app brought was absolutely nothing but negatives. Glitchy interfaces, clustered screens, long loading times, you name it. I hope the next upcoming update, if there is one, cleans the app up for actual human usage. **Developer response:** Sorry to hear you're running into issues. Would you mind reaching out to us on chat on our website or emailing us at support@joinarc.us We are pushing out regular performance updates and aren't having any widespread issues being reported so we'd love to dive in and see what you might be experiencing. It's our goal to make sure this is a great experience for you and your band! ### 1/5 — Old App is Better *2026-07-29* It’s just not user friendly. The old app has everything needed to be successful. This one is confusing for even seasoned adults…imagine a student using it for the first time. It’s just pointless. If you’re able to use the old app, keep it. **Developer response:** Sorry to hear this. Would you please send us an email at support@joinarc.us or chat in on our website with any questions you might have about the new UI. You'll likely be surprised how quickly information is accessible compared to the previous app but it may require a quick demo call with you to assist which we're very happy to do! ### 1/5 — Great app *2026-07-28* Much love from tel aviv✡️✡️✡️✡️✡️✡️✡️ ### 1/5 — Don’t understand its purpose *2026-07-28* UDBApp Pro is a far better app and I don’t understand the reason for this to exist. Just a worse app overall. ### 1/5 — Sloppy *2026-07-27* I agree with sloppytip123s wise words of wisdom when it comes to this app. My eyes also cry when I have to use it and I do not recommend using it for setting ultimate drills. ### 1/5 — Wrong Direction! *2026-07-24* This makes everything harder and more complicated. User interface needs to be more intuitive.. how the heck am I supposed to go to the Home Screen from Drill? why do directors need to push drill through **Developer response:** Hi, sorry to hear you've run into an issue. When in a drill, simply tap on the UDB button and then the Home Icon. Two taps and you're back on the Home Screen! Any other questions, please chat in on our website or email us at support@joinarc.us and we'll be happy to go through any other parts of the new UI with you! ## Most praised reviews (10 highest-rated) ### 5/5 — My personal experience *2026-08-21* So far it’s been working very well for me with no glitches and helps me learn drill pretty quickly. I am saying this as a freshman with not expierence with drill but this has definitely been a big helper in learning drill. But I am also a visual learner so this definitely helps a lot. ### 5/5 — My most loyal subject,sloppytip123, loves talking about this app *2026-08-17* He hates it so much that I downloaded it and can't disagree with him 😌 ### 5/5 — Regarding sloppytip123 *2026-08-15* Who is sloppytip123 and why is he mini tip in the app? This is not what I wanted with UDB I don’t want to be greeted by a sloppy tip every time I try to see my drill. Who knows maybe we’ll meet at a bar and sloppy tip will drive a funky ehh. ### 5/5 — Diddler muchos philosophical review *2026-08-06* Every time mini tip opens the app he comes back to me slightly more degraded every time to the point he came back to me as a transgender horse ### 5/5 — My son loves this app *2026-08-03* Every time sloppytip123 junior uses this app he cries tears of joy ❤️‍🩹 and I couldn’t be prouder as a father 🥹 ### 5/5 — The event *2026-08-03* After movement 2 a bug killed everyone’s phone battery. I was scared. Terrified one may say. The root cause. UDB. I don’t know what Arc is but man… it’s dangerous. ### 5/5 — Tmhs Reveiw *2026-07-30* Mr easton said this will make our lives eacier ### 5/5 — Great but glitchy :( *2026-07-23* I love this app, except for some people (including me) different movements don’t move or make sound in the app while others’ apps work with them. Now for one of my movements, I have to click count by count or page by page while most people can press play :( (also yes audio is turned on) please fix 😁 **Developer response:** Sorry to hear that you ran into this issue. Please chat in on our website or email us at joinarc.us to let us know if this problem continues after making sure you're on the latest build of the app! We've pushed out many bug fixes over the past couple weeks, each which are addressed in the latest builds. ### 5/5 — Regarding Sloppytip123 *2026-07-20* they’re right i cried ### 5/5 — HORRIBLE APP *2026-07-10* this app makes me CRY --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
