Adapty

Implementing in-app-purchases without Adapty would have been very painful.

In fact, all I encountered working with this company was a problem: 1. At the stage of creating an account and onboarding on their site, we met a simply non-working screen with an outdated onboarding guide, which they simply forgot about and did not pay attention to. 2. The documentation is very neglected with large inaccuracies and outdated information. 3. One of the most important disadvantages: Not a fully working SDK! 4. The second of the biggest cons: Disregard for customers and service problems and disrespectful communication! Support simply does not respond to requests about broken functionality and problems, and if you write to them in the general chat, they answered us so that we do not distract them with our messages while they throw presentations with graphs on the topic of subscriptions to each other to advertise themselves for new clients. Moreover, when answering us, they communicate in a disrespectful manner! I will mention that we paid money for this service for which we received in return: non-working functionality both on the site and in the SDK, zero support and disrespectful communication with us!
