ChatGPT took the data from my phone and indicated the app is taking too long to launch and my phone shuts it down. Any assistance on this weird sudden app behavior? ### 3/5 — Not working *2026-07-24, version 4.1.7* The app is great but all of a sudden it stopped working. It worked properly for few months then out of the blue the app won’t start up and it just closes on its own. Nothing seems to help. ### 3/5 — App not working *2026-06-28, version 4.1.6* The app won’t launch every time I open it crashes and sends me back to my Home Screen ### 4/5 — Unicode font support *2026-04-05, version 4.1.5* It would be great if the text notations supported U+1D100 - U+1D1FF (music symbols) and a bonus would be U+1680 - U+169F (ogham ᚋᚌᚍᚎᚐᚑᚒᚓᚕᚁᚂᚃᚄᚆᚇᚈᚊᚖᚚ᚛᚜). Being able to note these would help immensely. While editing notations, many of these are supported, especially ogham. However, when you are done editing, they turn into boxes. Appreciate the app! ### 2/5 — Absolutely awful annotations feature *2026-01-26, version 4.1.3* Annotations feature is the most buggy and clunky thing I’ve ever used in an app. The app is great for isolating parts during practice in the week for Sundays and on Sunday it’s great to have if you are an instrumentalist (other than the drummer, I’ll get there) who needs a chord chart. The synchronization feature for Sundays is great. When making annotations on song charts, the app makes it so you can’t put them anywhere but on the lyrics and with the limited space to annotate and awful navigation which will skip and think you want to add a note in annotation mode if you try scrolling, it really becomes an awful experience. This means if you are a drummer like me who wants to input transition notes into a song map or lyric rundown, you’re gonna have a bad time. Then when you get to Sunday service, many time annotations don’t load at all, meaning any important notes you had to remember are privy to being forgotten and manually switching to showing the annotations mid service is not a viable alternative many times. The app during personal practice has many and countless unintuitive interactions as well (it took me 2 hours of using it with just an original mix instead of what I wanted which was the part isolation that I had to pull up the card while playing the song to get the options you see for playback in the screenshots on the App Store listing for example… I’m a very tech versed guy as an app developer myself so I know how to use apps). App is good when it works, but most times doesn’t. This 100% needs way more work before I’d be comfortable using this in a Sunday service, luckily I’m a drummer and can make my part up if annotations I wrote don’t show up but other instrumentalists at my church have to use this and it was a clunky transition process to configure and took way to much digging to figure out how to actually use the app due to its unintuitive and awful UI/UX. ### 2/5 — Poor performance and constantly buggy *2025-12-13, version 4.1.1* Good bones, nice ideas, but this app is constantly buggy which makes it completely unreliable for consistent use. It takes minutes or hours to sync changes when made, sometimes even delaying for days. It means I wait until a few days have passed after a leader makes a setlist final before writing my notes, because otherwise your notes may be deleted if the song version changes. The handwriting support is poor, not smooth at all, making it hard to read. It’s buggy, laggy handwriting means you’ll be writing a note and it will turn into gibberish because you went too fast, or it will jump ahead when writing a note and listening at the same time, meaning you constantly need to pause songs to write notes. You can’t move the vertical scrolling screen with a finger when taking notes with Apple Pencil, you are required to use the play scrubber at the bottom. Would be a simple fix to have a setting to turn off finger writing input and only use pencil. The pause play button is way off to the side edge of the screen, and the hitbox is extremely small, meaning misses are easy to make, and music will keep playing when you need it to stop. And the library takes a very long time to load (sometimes literally minutes) each time when selecting a playlist, so good luck if you need to load one urgently. Also, don’t let your screen fall asleep if you are connected to a host and want to maintain the connection. It will drop (like during a sermon) meaning when you go back on stage, you must reestablish the connection, which can take minutes of fiddling around, which live settings don’t allow for. Using this app is a risk, and one that will bite you 1/10 times you use it, even if you know all the tricks to avoiding its shortcomings. Have a backup if the set is important. ### 3/5 — Great app if you don’t use a computer *2025-11-19, version 4.1.1* I didn’t purchase the app, my church leadership did. I will say the use is very easy and customizable! However, I prefer to see a full sheet of music in front of me, so using it on my computer isn’t an option. Even a full sheet on an iPad isn’t an option. I cannot play keys and swipe through a song for the next section while playing. I need an extra hand. So that’s why the 3 star review. 💖 ### 2/5 — Helpful but buggy *2025-10-31, version 4.1.0* When it works as intended, it’s indispensable. However every couple of months, it will lock me out of everything, not letting me listen to stems or view the charts. When I restore in app purchases, it sometimes works, but I usually have to delete the app and redownload. Support is not very helpful either - it took hours for them to understand what was wrong, even after sending them multiple screenshots. Once they realized the problem, I got a “sorry, good luck!” And that was it ### 2/5 — When it works.. it’s great *2025-10-29, version 4.1.0* I can’t believe how many times I’ve tried this app for practice.. and it has SO many “server connection” issues. When it works it’s fantastic - but I’m flipping a coin each time I try to practice with it (using my phone). Feels like this has be on the software side. Can’t even submit a ticket because of the connectivity issues to their server lol. ### 1/5 — Not a fan *2025-09-13, version 4.0.6* I’m sure it will take time to get used to it, but I’m not a fan. I don’t like the layout of the chord charts or the options for rehearsal tracks. I also despise the clicks. Just like my old Music Stand and tracks. Also—just needed to vent my frustration with this setup. ### 2/5 — Scrolling Issues *2025-09-05, version 4.0.6* I paid for the subscription and I’m mostly satisfied with the app. But it keeps glitching when I scroll? It sends me all the way to the end of the song sometimes and it can get a bit frustrating to try to scroll back into place on time while playing an instrument live. ### 4/5 — GOOD but … *2025-09-01, version 4.0.6* It’s GOOD BUT …. If Multi-tracks doesn’t have the song you/re a bit screwed. You should be able to load up your own music as well. ## Most critical reviews (10 lowest-rated) ### 1/5 — Não abre *2026-08-13* Eu e meu namorado resolvemos pagar o app pra gente servir no louvor da igreja, mas o aplicativo simplesmente não abre no meu celular. ### 1/5 — Still not working *2026-08-04, version 4.1.7* I’ve redownloaded the newest version several times and it still leaves me stuck on the loading menu before crashing and taking me to the iPhone Home Screen. It’s been like this for about 1.5 months for me ### 1/5 — Não abre *2026-08-03* O App não abre no meu Iphone 16, ele simplesmente não funciona. ### 1/5 — App still crashing *2026-07-24, version 4.1.7* App still crashes on the launch screen. iOS 26.3 ### 1/5 — Não funciona *2026-07-20* Simplesmente não funciona no meu celular ele nem abre troquei de aparelho e sem chance de pegar ### 1/5 — Help *2026-07-16, version 4.1.7* I downloaded the newest update and now it won’t even open for me so you might’ve fixed it for some users but made it worse for others. Help!!! ### 1/5 — The app is crashing *2026-07-09, version 4.1.6* I don’t know what is happening with the app. I tried to login but it only show the logo for about 20 seconds and the the app closes. I need help fixing this. I tried to uninstall the app, reset the phone and still happening. I really love the app bit lately a haven’t been able to use it and I really need it ### 1/5 — No chords? *2026-04-16, version 4.1.5* Even tho im paying for the solo bundle it does not let me view chords? Since when? Whats the payment for then? ### 1/5 — No es completa *2025-12-05, version 4.1.1* Es una pena porque no están todas las canciones completas, algunas aparecen a la hora de que quiero ver los Charts me dice que solicite. Es una pena porque me siento decepcionado ### 1/5 — Inaccessible to a blind musician *2025-09-22, version 4.0.6* I am a blind musician, and regret to inform that several key aspects of the app are inaccessible with OiceOver. Contacting support has given me a non-committal timeframe for working on this, but the app remains mostly unusable for me in the meantime, until this is done. I would love to revise my review and say that the developers are responsive, so please show me this, because for the moment, the most basic features of the app, like playback and part selection, remain unusable to me, when there are many media apps that work perfectly with VoiceOver. Thankfully the website "sort of" works, but of course that doesn't accomplish all that I need to be a fully participating and contributing member of my worship team, allowing me to serve. Please do better and be accessible from the start, there are several blind musicians I know that would love to use their talents to glorify the Lord through worship. Thanks. ## Most praised reviews (10 highest-rated) ### 5/5 — Growth! *2026-08-17, version 4.1.7* Form any musician looking to grow in discipline and skill. Use this app ### 5/5 — Amazing app!!! *2026-05-20* Really helpful and it has a great integration with Playback. ### 5/5 — Aplicativo excelente! *2026-04-24* Aplicativo essencial e absolutamente intuitivo **Developer response:** ¡Gracias por tu opinión! ¡Nos alegra mucho saber que te está funcionando bien! ### 5/5 — Super adaptive, intuitive, and profesional, also a lifesaver *2026-04-03, version 4.1.5* When I first got this app, I was a little worried, this is because we had very limited resources as a new church; however, as a guitarist and worship leader, I was aware we needed tools to help give are musicians the best experience possible to be able to focus on God during the worship service but still play with excellence; ChartBuilder was the answer: ChartBuilder has every song I have looked for, it has many languages and is very adaptive, with it syncing in real time with the setlist we can change keys and it auto updates on the chart, if we ever need to play a new song because the pastor or prayer team requested it ChartBuilder has the charts and ability to adapt. Whether you are a church that has all the songs ahead of time or one always changing throughout the service ChartBuilder has everything. ### 5/5 — Great *2026-03-07, version 4.1.4* Love using Chart Builder ### 5/5 — Amazing for Learning and Practicing music parts! *2026-01-08, version 4.1.2* The tandem of the RehearsalMix audio and auto-scrolling charts is amazing.
