Question
Looking into App Store or Self Fulfilled but we don't know how to get the app service to stop working once they have it on their devices. It's a subscription model that we will charge $47 per month for the service, but if they cancel, we need to cancel their usage of it. Need to know how to launch this thing ASAP. Any help?
Answer
Your app should include a login that would validate with your servers who is/isn't an active member.
Let's hop on a quick call and we can discuss specifics.
