In-App Subscription Implementation & Management

1. Qonversion SDK provides three simple methods to manage subscriptions:
   • Get in-app product details
   • Make purchases
   • Check subscription status to manage premium access
2. Qonversion communicates with Apple or Google platforms both through SDK and server-side to process native in-app payments and keep subscription statuses up to date.
3. You can use Qonversion webhooks and API in addition to SDK to get user-level data where you need it.

See the quick start guide documentation.

Analytics

Qonversion provides advanced subscription analytics out-of-the-box. You can monitor real-time metrics from new users and trial-to-paid conversions to revenue, MRR, ARR, cohort retention and more. Understand your customers and make better decisions with precise subscription analytics.

A/B Experiments

Qonversion's A/B Experiments feature provides everything required to quickly launch paywall and other monetization experiments, analyze results and roll out winning versions without releasing a new app build. Qonversion A/B Experiments include:

• User segmentation by country, install date, app version, free/paying user
• Traffic allocation
• Advanced subscription analytics
• Visualization of A/B experiments results
• Statistical significance of the results
• Roll out winning versions without app release with remote config
