★★★★★ I payed a lot of money over the years and now they don't support any offline access anymore….
★★★★★ It's horrendous and they should not allow them to make money like this
★★★★★ Coming from a legacy company like Hudson who charges a premium price for their Digital products but can't keep up with the digital world.

★★★★★ The App would stop crashing every time on my iphone 14 pro max….
★★★★★ You can't search the books you've bought, you can't even just see them, you have to scroll through everything to find your book, then the app crashes anyway.

Latest reviews, Brazil App Store.
I have 40+ drum books and videos from Hudson, in both digital and physical copy, I generally like the company but don't expect to get anything shipped to you within a few days if you order the actual book/video...I don't get it - I ordered and paid for a book and didn't get it for 14 days after I purchased!!! Come on guys - it's 2026 - it's not rocket science to get orders iut to customers!!!!
There is no way to use the books you buy offline. Not that I have found. I reached out & there was no response. Some of the books can be found digitally elsewhere for your iPad such as Apple Books. I find that to be a more reasonable situation. I’m on the train as we speak with WiFi through my phone but don’t get to see my books. The people who pay for books are obviously not the problem MFs.
This entire app is so helpful to learning and makes getting better on the drums so efficient. Everything you need is in one place. You can annotate and bookmark. And there’s examples to go along with what you’re trying to learn. I don’t know how you efficiently learn without this.
The e-books are very convenient to use and they are very easy to access
Everything to read and learn
I’m on this app every single day for hours. Easy to navigate, great features for students, great library selection of books. Highly recommend.
