Subscription app development puts the business model inside the code. Pricing tiers, trials, introductory offers, upgrades, grace periods and cancellations all have to be built on top of Apple's StoreKit and Google Play Billing, then mirrored on your backend so the app always knows who is entitled to what. Small mistakes here show up directly as lost revenue or angry reviews.
The guides in this category cover that layer from both the product and the engineering side. They explain how paywall design, placement and timing affect conversion; how StoreKit and Play Billing handle products, renewals and server notifications; when a subscription platform such as RevenueCat saves time compared with building receipt validation yourself; how to structure free trials and introductory pricing; and which product and messaging levers help keep subscribers, from onboarding that shows value quickly to win-back offers and billing retry handling.
Appryze builds Android, iOS and web apps with in-app subscriptions and handles store submission free with every build. Our app development page explains how we scope subscription products.
A paywall is the screen that asks users to subscribe or pay to unlock premium features or content. It typically shows plan options, prices, trial terms and benefits. Its design, timing and placement, such as during onboarding or after a user hits a limit, strongly influence conversion.
Rules depend on platform, region and app category, and they have changed in recent years after legal and regulatory decisions in several countries. In some cases apps may link to or mention web purchases. Check Apple's and Google's current guidelines for your markets before planning web checkout.
A free trial gives full premium access for a limited time, after which the user pays or loses access. A freemium app offers a permanently free tier with limited features and charges for upgrades. Some apps combine both, offering a trial of premium on top of a free tier.
