Is only releasing on iOS necessarily a bad thing?

Today, we finally launched it.

However, it was only released on iOS, and the AOS and desktop versions are not being considered yet.

1. In previous projects, AOS users accounted for less than 5%.

2. The quarterly processing is cumbersome.

Considering points 1 and 2, I concluded that the cost-effectiveness is not there. But not doing what we were working on makes me a bit anxious. Should I start now? I'm also worried. 😟

Can you take a look at the released service and give me your thoughts?
