Smartlook Qualitative Analytics is nice to have some qualitative data about how people interact with the product (screen recording & heatmaps).
For quantitative analysis I'm using either Mixpanel or Amplitdue;
Mixpanel + Hotjar + trying to talk to as many users as possible. Too often I'll find blind spots in our quantitative analytics when I start talking with users about how they actually use our product
