Which analytics service do you use with early prototypes (first 5, 10, 50 users), where each user flow is vital?<p>I just spend two days on Google Analytics for my new simple app. The only usable metrics I found are: "Avg time on page" and "Nr of times each page was open" and correctly setting up pageviews and events was a pain in the ass. I would love to pay 10$ for a simple analytics tool where I can just see each user flow. Google Analytics feels like a big overkill for simple prototypes.
