An interesting development of the project without advertising. I see this for the first time. Very poor informing of the population.
However, the application as I understand it shows good results?
I think the number of downloads has already exceeded 50,000?
I think for a long time already

Most likely the number of downloads is close to 75-80 thousand. By the way, as you can see, the developers direct the maximum amount of effort and money to the development of the product itself. This will lead to a good result in the future!
If you conduct a marketing campaign early - then people will look at the project and leave because of a non-working product.
The strategy is perfect.
