FullStory - See every click, swipe and scroll on your site.

If their was a way to hook this into mobile iOS or Android I'd jump on it in a second. Seriously.

When you're building a new products, user feedback is critical. You can gather feedback in a variety of ways, through in-person customer development interviews, surveys, and by simply looking at the data. I'm particularly fond of doing user testing (UserTesting is an awesome tool for this) although its only a "simulation" of what your users are actually doing.

FullStory captures a screen recording of your site visitor's actions and behavior within (cue Steve Irwin impression) their natural environment. We've used it many times at Product Hunt to better understand how people are using new or beta features we're building. It's 👍🏼.

Pros:

A "super power" for user research

Cons:

Often the video stream remains static when the user opens a new tab, pauses

Impressive -- ProductHunt has been driving a decent percentage of our site traffic today. Please come on over and sign up if you're interested!

killer app $199 a month to start is pricey should be a deal for startups

Should also check out @Heap, @fullstory, You guys could make magic if you teamed up.

We use FullStory at RelateIQ for the support process. It's radical.

beat me to it by a second :)

@jgw — Is FullStory going beyond event tracking and activity recording? I am curious because I have used similar tools in the past but never found them an adequate replacement for usability testing.

@muldster : At present we're still focused on recording sessions and tracking events, but it's still early days. We have a lot of ideas about higher level analysis, but would love to hear where such tools have failed you in the past, and what you'd like to see.

This was a godsend. Amazing product, it helped us catch bugs we couldn't see before
