The MOST annoying of these bugs is the way it disconnects ANY audio playing on my phones through my car stereo as soon as I open the app. 😬. Can the developers PLEASE fix this? Pretty please? 🙏 PS: I’d also like to be able to DELETE animations and images I’ll never use - like all the American-themed junk, and the ride-share icons and animations. And finally I’d like to be able to rearrange them in preferred order. 😉 ### 4/5 — Tape to stick it on *2026-06-11, version 2.7.4* I love this but the tape does not work please fix this ### 3/5 — Bluetooth *2026-04-02, version 2.7.1* App not connecting to Bluetooth ### 4/5 — Actualizaciones *2026-03-02, version 2.7.0* Habrán mas actualizaciones con mas variedad en un futuro? ### 4/5 — Music is broken *2025-12-28* This app is great, it lets me do more than I thought it could. I can upload my own photos and gifs, as well as edit them and make my own graphics and animations. The one thing I'm bummed about is that the music doesn't work. The only song that plays is the pre-programmed jingle bells song, the rest of my library is either silent, or makes a long buzzing noise. Either way, music won't play so I can't sync it up to the graphics. **Developer response:** Thank you for your report, our engineer will fix the bug you reported.Our app has a Telegram group for easy communication and problem-solving. Feel free to join: https://t.me/CoolLED1248 We can talk in detail in the telegram ### 3/5 — Good could be better *2025-12-10, version 2.6.6* App has a lot of built in pics and gifs which is cool. What would be AMAZING is if they allowed us to share our creations. I use this at work and would love to send my creations to a college for when I’m out they can update the ticker. Food for thought ### 4/5 — Good *2025-11-24, version 2.6.6* The app is good. Definitely needs an update with more pre-programmed quick signs. Otherwise printing, your own messages is great. ### 3/5 — Clock function is non existent *2025-11-04, version 2.6.6* I wish the app actually looked like the photos In the App Store. I can’t find the clock function anywhere or the discover tab. ### 2/5 — Bilder Update *2025-11-02, version 2.6.6* Es wäre schön Weinmann neue Bilder Schriften Logos und oder die Uhrzeit benutzt werden könnte bitte Update für neues. ### 2/5 — Needs Work *2025-10-26, version 2.6.6* App rarely ever updates. No way to share animations to download. My biggest dislike is that it displays the loading percent on the led bar when you load an image or graffiti. ### 3/5 — Анимации *2025-10-17, version 2.6.6* Здравствуйте! Приложение интересное, но мне не хватает анимаций. Подскажите, пожалуйста, планируется ли обновление материалов(из-за не хватки)? Или же есть сайты (если будет ссылка, при много буду благодарен) где можно найти и добавить новых анимаций? ### 1/5 — Słabo *2025-10-14, version 2.6.6* Zawiesza sie i rozlacza ekran ### 1/5 — Doesn’t Update- Basic Stuff *2025-10-09, version 2.6.6* Funny my app doesn't look anything like what is shown in the app store! ### 3/5 — 미러 *2025-09-19, version 2.6.5* 미러모두 좌우반전기능 없나요 ## Most critical reviews (10 lowest-rated) ### 1/5 — Eksik *2026-07-11, version 2.7.5* Bende hic bir ozel gorunum yok hepsi bos ### 1/5 — Non funziona *2026-05-25, version 2.7.3* Dopo aggiornamento non si collega più ormai inutilizzabile non si può cambiare le scritte non serve più sarebbe bello avere un programma sostitutivo me ne farò una ragione e non comprerò più articoli del genere ### 1/5 — 連不上 *2026-03-01, version 2.7.0* 破東西…. ### 1/5 — Update broke it *2025-12-19, version 2.6.9* The most recent update broke a key feature in the app and is practically unusable if you plan on making your own animations. ### 1/5 — Funktioniert mit iPhone 17 Pro nicht mehr *2025-12-17, version 2.6.9* Die App verbindet sich nicht mit einem iPhone 17 Pro nicht. Mit einem iPhone 15 geht es. ### 1/5 — Thai language not working *2025-12-14, version 2.6.9* Thai language not working please fix ### 1/5 — Easy to use but lacking basic text operability *2025-12-13, version 2.6.9* 1. There is no comma (punctuation mark) to use in the text. 2. There is a character limit for each text message, but it doesn’t tell me what it is. 3. You can only have one line of text in the badge at a time. I would like to include several sentences. 4. I can’t reach the developer’s website, so I hope they read the comments and help me out! Thank you. ### 1/5 — POS *2025-12-09, version 2.6.6* My bluethooth can’t even find your device. Your instructions don’t say to push any buttons on the LED display so I can connect to it through the app. I would rather throw it away before I give it to someone else. There is no way to connect at all especially when there is no button on your device to have the Bluetooth to pick it up ### 1/5 — Will not connect to iPhone 16 *2025-10-26, version 2.6.6* Worked well with an LED hat on my previous iPhone. Recognizes the hat now but will not connect. This means there is no way to change the message which makes the app useless for my use case. There are fairly extensive troubleshooting methods in the documentation but some of them are nonsensical like powering off the device before connecting (the device is not transmitting when powered off so cannot connect to anything). ### 1/5 — All *2025-10-19, version 2.6.6* When will the app ever update cause I don’t like the way It look ## Most praised reviews (10 highest-rated) ### 5/5 — 可以打中文字嗎 *2026-07-19, version 2.7.5* 有辦法自己編輯要打什麼字嗎 ### 5/5 — Türkiye *2026-05-12, version 2.7.3* Würden Sie bitte auch die Türkische Flagge mit bei legen ### 5/5 — Más variedad *2026-04-30, version 2.7.3* Estaría bien, poder descargar más imágenes, pero me encanta👏🏼👏🏼👏🏼 ### 5/5 — ! *2025-12-19, version 2.6.9* Как установить время? ### 5/5 — Pleasantly surprised *2025-10-31, version 2.6.6* Super fun designs and solid connectivity. No issues thus far. ### 5/5 — Love this app but have some suggestions *2025-10-12, version 2.6.6* I love this app and with my LED sign you can have (almost) infinite possibilities! And works really well on an iPad with an Pencil 😃. I have 2 suggestions to make the sign even better • #1 is having more colors like orange or purple because that will look really good in Halloween signs and also more possibilities. I feel like the hardware is in the sign • #2 is having Live Activities sync to the sign like a countdown timer that you can customize or the score of a game. Overall I love this app and sign, 5 stars from me 😎 ### 5/5 — ⭐️⭐️⭐️⭐️⭐️ Feature Request from a Daily Power User – Big Red Connect (OKC) *2025-07-14* I use CoolLED1248 daily for my mobile brand Big Red Connect, serving the OKC metro. The app is stable, simple, and reliable — love the font control and preview mode. Bluetooth has been flawless. That said, here are a few feature ideas that would make this a next-level tool for professionals: 1. Message Scheduler – Set messages to change automatically by time of day or day of week (e.g., day vs. night use). 2. Auto-Rotate Presets – Let multiple saved messages scroll on a loop every few minutes without manual switching. 3. Custom Profiles – Save full message sets for quick swaps (e.g., “Airport,” “Weekend,” “Errands”). 4. Smarter Static Layout Tools – Ability to visually anchor phrases together or preview how chunks will break across static display screens. 5. Cloud Backup or Sync – Save presets across devices for multi-sign setups or backup. Thanks for building a great app — I truly use it every day. If any of this is already in progress, I’d love to support or test! – Big Red Connect **Developer response:** Thank you for your advice, I will report your needs to my team. ### 5/5 — difference *2025-05-20, version 2.6.1* I have two panels. one 16x64 U and the other 16x64 M Plus. Why does the application offer different animations for the larger panel and only a few compared to the cheaper and smaller panel? ### 5/5 — Brilliant app *2025-04-20, version V2.5.9* Works perfectly. A lot of possibilities. I just wish it had a playlist mode for the text (play the saved texts sequentially). Good job overall! ### 5/5 — Easy to set up and works! *2025-02-24, version 2.5.7* Bought a sign a couple years ago for my restaurant. Very durable even in Texas heat. The software is simple and the author has fixed a lot of bugs! Works great on my iPhone 16 Pro Max!!💪💪 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
