I was excited when I heard about this app because I was looking for something like this. I am curently using an app called fighter verse that is just like this but way better than this one and you can use all translations and it only cost three dollars the first time you download the app. However, when I downloaded this app, I could not switch to NIV without paying several dollars. Now this app is pretty much useless because I do not use King James version and I am not willing to pay a ton of money. To fix this, I would suggest you letting the user pick the translation they want to use for free. Thebes if they want to Switch they would need to pay.
