How do download gospel library into iPhone 10

I have been trying to download gospel library into my iPhone X but it does not let me. I have no problem with the Android when I download it. Just upgrade my phone and I really need the gospel library but it did not let me download. Please help is very much appreciated

Hi, I have an iPhone X and am able to install and run Gospel Library without any problems. Where are you trying to download it from? If you open the App Store, then search for Gospel Library, you should see an install or download button there. Is it giving you an error message?
