in app purchase - How can we implement the "time-limited free" feature in Android app? -


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

now wanna make free in period of time advertisement.

however, google play console not allow adjust product's price below 0.99.

so, after survey, think implement feature server.

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

therefore question :

above think, i'm not sure if there other better or easier solution issue? example, maybe no need server?

or using own server way implement "time-limit free" feature?

thanks you~!

there 2 ways:

  • if have own server can implement unique user , removes adds days
  • if planning charge monthly/annually can implement subscription have trial period implemented google.
