I see your point. I mis-read your concern. I implemented the policy to check licensing at intervals, to minimize "sharing" through temporary account setup for app download purposes.
A service for this is an interesting concept. Is there any additional interest out there? We may be interested in providing this service (we are currently developing an app that requires device specific licensing, so providing it as a service is a consideration also), but it seems like it is a very limited market, unfortunately. -Jim On Sep 2, 2:11 pm, Kevin Tambascio <ke...@appbrewer.net> wrote: > Hi Jim, > > I originally read this section when implementing licensing: > > Caution: Per-device licensing is not recommended for most applications > because: > > - It requires that you provide a backend server to manage a users and > devices mapping, and > - It could inadvertently result in a user being denied access to an > application that they have legitimately purchased on another device. > > I didn't implement this because of needing to have a backend server. > Also, at the time, my app was more consumer focused, and therefore I > wasn't too concerned since the average user may only have 1-2 devices > (phone and a tablet, etc). > > Are there any paid services that offer this as a backend?
