The site is regularly unavailable, and very often (more than 3 times a week) you encounter the fact that the site either gives a 502 error or does not open at all. I tried to download the app. It's terribly uncomfortable. And, of course, there are big questions about the schools themselves. Many teachers do not complete their homework or grades. The paid version is unnecessarily expensive.
There are no servers, the site looks terrible, there is no mobile version. Also, the site endlessly lies down that it does not look at the ratings, does not look at the DZ, I beg you, make a mobile version (I do not even consider using the application, this is even worse)
It's not bad as an electronic diary. It's a pity not all teachers actively use it. There was also information that the project would be closed. I don't understand why we started to close it.
