Hi, I need someone to add the "In-App Purchase" option to an exisiting iPhone app. The App is offering property data. At the moment, once purchased, the user can use it forever.
Now I want to change the busienss model to subscription. The App shall be offered for free for a limited period of time, thereafter the user shall buy one month (non renewing) subscription if he wants to use the App. After one month, he needs another subscription, and so on...
The App is called "Versteigerungszwang" (no need to download). My developers seem unable to add "In-App" feature, that's why I am looking for someone who can add this.
To me (as a non-IT guy) this seems to be a standard solution which can be implemented quickly (in a couple of hours). But if I am wrong and need to increase the budget, please let me know.
Happy to answer additional questions.
