iOS App With Purchase Subscription

I am looking to develop an iOS application that includes a purchase subscription model. While I've skipped detailed functionalities for now, I am open to suggestions and innovations to make this app a success. Add subscription offers that appear to the person who downloads the application from the store, allowing them to subscribe to a limited-time package. After the period ends, they cannot browse the application except after making a purchase again, meaning a subscription system linked to the store. - **Skills Required:** - Expertise in iOS app development - Knowledge of in-app purchase and subscription services - Proactive thinker with creative ideas for app functionalities - **Timeline:** My project has a high-priority status, needing completion as soon as possible. It's crucial that you have extensive experience with iOS development and understand the best practices for implementing in-app purchases and subscriptions. Your strategic suggestions will be highly appreciated to make this app user-friendly and profitable.
