It is one of those things I think should have implemented from the start but I didn't. I know how many users visit the site but I don't know exactly how many users log back in to reuse the app, what percentage never come back, those kind of things.
guyssss, plssss, I've seen big comapnies do the same mistakes. Don't do that, you can't afford to fly blind and make that kind of mistakes. Many free tools are out
Heap and Amplitude for instance, can help with users behavior analytics and you can install them by yourself all free.
