The integration with Google Play and the Apple Store for payments and subscriptions. The user interface designing the Paywall is very intuitive and easy to use

For me revenue cat is the best subscripton "manager" in market. I like the easy to use SDK and pretty good documentation

RevenueCat has the tools you actually need. One example is virtual currencies — you can attach units to a subscription, like minutes for transcription, that refresh on a schedule. You can also run A/B tests, and you can set up an extra offer at the cancellation step — for instance, when a user wants to cancel their subscription, you can offer them a discount like 50% off, and this often works. The solutions RevenueCat provides would take a lot of time if you had to build your own server-side implementation. Instead, you get a ready-made solution that's free while the user earns up to $2,500, and if you go over that, the cost for these services stays low 1%.
