Can anyone offer any suggestions as to an app that would put the drm on my ebooks? i only see the one app in the shop and it only has 5 reviews...
I did some research and here are some apps I found, please check if any of these fulfill your requirements :
Digital Content Sales with DRM -- Paid app (I think this is the one you talking about)
Courses & Memberships -- Free to install and Pay as you go
Conjured Memberships -- Paid app
