Nice thing is you can export the music as jpg, convert that to pdf, then import to Forscore with a very clean pdf. ### 3/5 — Good, but needs a little change *2026-03-04, version 1.3.8* Apparently, when I was practicing trombone with a recording of page 6 from tradition of excellence trombone book, page 4, recoding 5 has ‘accidentally’ mixed up with the test on page 6! But otherwise, the app has helped me practice well. Please fix this as it is a little confusing. ### 4/5 — Can’t figure out how to record. *2025-09-09, version 1.3.8* It is a great app. It lets me see what note I am playing, which has been helpful. One problem, though. I can’t record myself playing. Can you fix that? ### 4/5 — Okay *2025-02-06, version 1.3.5* It’s just glitchy. Also you guys should add a custom tempo controller for the audio. Also some songs aren’t in the audio that are in the book. And the audio can’t play even though it’s in the app. It’s very hard to play a trombone with a really big concert coming up and not knowing what the songs sound like. ### 3/5 — Audio not Available *2025-01-17, version 1.3.5* After page 24 of my book it started saying “sorry, this content is not available” so I couldn't listen to the audio of how it sounds. Before this it was great ### 4/5 — Okay *2024-12-18* It’s just glitchy. Also you guys should add a custom tempo controller for the audio. Also some songs aren’t in the audio that are in the book. And the audio can’t play even though it’s in the app ### 4/5 — Okay *2024-12-10* It’s just glitchy. Also you guys should add a custom tempo controller for the audio. Also some songs aren’t in the audio that are in the book ### 4/5 — Does it’s job *2024-09-28, version 1.3.5* For me I have been in band playing bass so I had the physical book which allows you to play along at home for free by I believe it does what it’s should, nothing else ### 3/5 — Download this! *2024-09-28, version 1.3.5* It’s helpful (+2) and nice (+1) and the book is great (+1) but the only bad part is that the interface looks like a sketchy website (-0.5) and the buttons are small (-0.5). Overall pretty good! A good download for students in band. -Madden, a 6th grade clarinet player. ### 3/5 — It’s pretty glitchy *2024-06-16, version 1.3.5* This app is really glitchy, as when I attempt to listen to each line it just won’t load. And when I tried to use the tuner it wouldn’t work either. ### 2/5 — Please stop charging us for books *2024-06-02, version 1.3.5* I am a twelve year old flute and drum player for my school band and I am on summer break without a book right now so I downloaded this app but the flute and drum books cost 10-12 dollars for one book and I am not paying 24 dollars for 2 books. ### 3/5 — Why? *2024-04-12, version 1.3.5* I am a 11 yr old viola player, I am in a orchestra and I am the best viola player in my entire class, I would love to be able to play alongside your solo “paseo por Madrid” whit the track like I do whit my professor because I have a big concert coming soon and I tend to play music way too fast,so sometimes it is just a little bit easier to play with the tracks, plus I already have the book in real life so it’s not very easy for me to pay, although I do have a understanding of the fact that you need money , but if I already bought the book, I would love to not have to pay online. ### 3/5 — Needs improvement *2022-09-26, version 1.3.1* PLEASE add an option to disable the motion/animation between pages in the book view. Huge waste of time waiting for the page to slide out of view rather than just having the next page appear instantly. ### 3/5 — Mic does not pick up *2022-09-18, version 1.3.1* The mic does not pick up on the recording so its really only useful for playing your music ### 4/5 — Great app *2022-08-26, version 1.3.1* Had trouble at first but turned out good in the end ### 4/5 — Nice app *2022-06-28, version 1.3.1* This app is really helpful and it just makes it so easy with the microphone if I need to slow it down and know how fast I am going ### 3/5 — Not bad *2022-03-24, version 1.3.1* Hello ! So I’m having problems on turning the pages and I can’t figure it out so yeah. ## Most critical reviews (10 lowest-rated) ### 1/5 — Why do I need this app? *2026-05-19, version 1.3.8* I bought the hard copy book and it suggests downloading this app. I assumed it would play the music pieces. Nope, it’s just the book. Removed the app as it’s useless. ### 1/5 — Stole my book, and didn’t work *2026-05-15, version 1.3.8* I added my Standard Of Excellence Book to it, but it didn’t add it to my library, and it kept saying “This product code has already been used.” 0/10 waste of money ### 1/5 — Doesn’t even let you download *2025-12-18, version 1.3.8* Wont let me download and when I put my info in TO download it it still doesn’t work ### 1/5 — Videos don’t work *2025-06-05, version 1.3.6* I’ve just downloaded the app for use with the book, and I cannot get the videos to work!! Very disappointing- this would be a great resource if it actually worked. ### 1/5 — Very poor, non-functional app *2024-09-22, version 1.3.5* Completely unusable, non-functioning app. Follow all the instructions, songs will not play on iPhone. if I’m in a lesson I can’t sit and watch the wheel spin trying to load one song to play along with. Total waste of my and students’ time. Why not make your app functional?! ### 1/5 — Terrible. *2024-02-18, version 1.3.4* Just started to use the app for my band class. The interface is like a sketchy websites. I was trying to do some pass offs (or the go for excellence exercises) and the app refuses to let me record whenever I tried playing the already made track it didn’t let me and whenever it did play it would repeat even if I left the line back to the Home Screen it would repeat until I closed the app. Would not recommend just get the physical book or would save you so much time. ### 1/5 — Not working *2023-07-19, version 1.3.3* Just downloaded on phone and computer and both won’t open ### 1/5 — The most horrible app someone could come up with *2023-02-28, version 1.3.3* Literally the worst app known like it doesn’t even help me with playing makes it the worst experience makes me slow down and how hard it was to even use it like this is making me want to quit playing. ### 1/5 — Is this app still being supported? *2023-02-06, version 1.3.3* Crashes on my phone and can no longer purchase liscences? ### 1/5 — App is terrible *2022-07-12, version 1.3.1* Downloaded the app for Interactive IPS on my iPad. Looking for the videos that are promised for the ‘Vibrato Basics’ for violin book. The book says to ‘follow the on-screen instructions and use the 16 digit User License Code to begin enjoying all the features of the IPS’……well WRONG, all I get is a ‘invalid code’ message when I try to access the content. Tried to use the help function on the website (app) to contact the company but after typing my message I found out the SEND button isn’t working. I’m very sorry I even bought the book. ## Most praised reviews (10 highest-rated) ### 5/5 — Graphics and stuff *2025-01-21, version 1.3.5* My piano teacher has me use it and it’s pretty good except for the graphics could be a lot better and smoother but I like the tuning fut ### 5/5 — Where is the 16 digit code *2024-09-24, version 1.3.5* Umm please tell me where the 16 digit product code is so I can practice like it is the best just where is the code ### 5/5 — Idk if I wrote the right amount of stars but wheatever *2023-11-02, version 1.3.3* THIS IS THE BEST APP EVER! Hi, This is coming from a clarinet player. This has been very useful to me when I lose my book. Thanks! ### 5/5 — It’s Great *2021-10-23, version 1.3.1* I love the app, it was recommended by my band teacher! The only thing I don’t like is how you have to have a book code. Some people want to learn and they don’t have a real book to look off of. ### 5/5 — Goated *2021-08-31, version 1.1.9* It is amazing ### 5/5 — Cool *2021-08-30, version 1.1.9* Am is the are god trombone player cuz of app and is the haha me in big hose cuz am rikh haha ### 5/5 — Awesome music app *2021-02-17, version 1.1.9* This is awesome for the saxophone my son is really good at it.🙂🙂🙂🙂🙂🙂🙂🙂🙂🙂 ### 5/5 — Good app *2020-10-20, version 1.1.8* Good app I use it to practice my trumpet lessons ### 5/5 — Decent *2020-09-27, version 1.1.6* I would’ve gave this a lower star review but this app is not looking so good in ratings so I’m giving it 5 stars. This is pretty useful if your book is damaged and you don’t want to pay for it again or you just don’t have it with you. I won’t be using this that much but it’s good for me to have. I’m a percussionist and the pages in the digital book seem to match the physical copy. I heard that there’s a recording feature but I probably won’t be using it. Overall this is pretty useful. Definitely doesn’t deserve the 5 stars I’m giving it, but I wanted to be nice. ### 5/5 — Teach piano *2020-04-21, version 1.1.3* My students love this app for their lesson books. Illustrations are charming and there are many fun tunes. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
