My situation is, I have implemented an in-app billing product "remove ads" in my app for 0.99.

Now I wanna make it be free in a period of time for advertisement.

However, google play console not allow us to adjust product's price below 0.99.

So, after some survey, what I think is to implement this feature by a server.

I means, to check users' account by our server before calling google's in-app billing service.

Therefore my question is :

Above are what I think, but I'm not sure if there are other much better or easier solution about this issue? For example, maybe no need a server?

Or using a own server is the only way to implement the "time-limit free" feature?

Thanks you~!

There are two ways:

  • If you have your own server you can implement unique user and removes adds for some days
  • If you are planning to charge monthly/annually you can implement subscription which have trial period implemented by google.

I have written a library that allows for this sort of behavior. https://github.com/FutureHax/UberVerificationSystem
