If you have the funds, it's worth considering Roistat, but if not, then you should think twice. I chose Primegate. UTMStat is also inexpensive, but I only tested it in the free version. I didn't opt for the paid version because I noticed several issues, such as errors in processing data on incoming calls. In my case, this negated all the advantages of the system, as I could have used services from Google and Yandex. Additionally, I found the interface to be too complicated. The integrations also leave much to be desired.
