Cameron here, designer for The Informant. We’ve just launched as a Heroku addon and are looking for feedback, insights & whatever you can throw at us.
What it is: The Informant is usability testing in the form of error tracking. It simply watches ActiveRecord validations and tracks when errors are triggered. It’s a great way to learn where users are making mistakes, so you can improve the usability of those areas.
For example, maybe you’re getting abandonment rates on account creation or checkout. The Informant will tell you if users are simply mistyping their phone number a lot, and the fix might be as simple as a copy edit or more forgiving backend logic.
tl;dr your users make mistakes all the time. Now you can learn where and why, and fix it. :)
