Thank you for your candid feedback. I'd like to address each of your points:

Google Play integration:
You are absolutely correct - this was our mistake in communication. We indeed don't have a Google Play integrator yet, despite it being erroneously advertised. We sincerely apologize for this error and for misleading you. We will immediately correct this information in our marketing materials.
User Interface (UI/UX):
We appreciate your honest opinion about the interface. We recognize that there's always room for improvement in this area. Could you share more specific feedback about what you find difficult or what you'd like to see improved? Your suggestions would be invaluable in helping us enhance our product.
Development pace:
We understand your frustration with the pace of development. While it may seem that changes are happening slowly, I assure you that we are working hard to improve our product. Nevertheless, your feedback is a signal to us that we should accelerate our efforts and perhaps communicate our progress more effectively.

Once again, thank you for your honest review. We take it very seriously and will use it to improve our product. If you have any additional suggestions or would like to discuss your experiences in more detail, we would be grateful for further contact.
We apologize for the inconvenience and thank you for your patience. We will do our utmost to meet your expectations in the future.
