Kupima removes the traditional barriers to getting proper user feedback – and at a surprisingly reasonable price per user test.

What marks Kupima out from its competitors is its flexibility – you can define your own bespoke questionnaires or base your test on a template, view summarised charts of the tester responses you receive and even have it create summary reports for each test in PDF format. You also get a powerful management interface which allows you to organise, edit and review as many tests as you like from a single place.


Userlytics schedules, recruits and executes in-home panels for anything from pre-market banner and creative testing to application and website usability-testing. Userlytics is truly unique as it records participants using their own webcams (facial expressions and spoken thoughts), and their actions on their desktop (what they do), as they work through the creative being tested.

Say good-bye to testing and optimizing after the creative has launched. Now you can optimize before launch and still hit your tight deadlines.

CogTool is a general purpose UI prototyping tool with a difference – it automatically evaluates your design with a predictive human performance model (a “cognitive crash dummy”).

To use Cogtool today, simply create a storyboard of your design idea with sketches, images or on a canvas with CogTool’s widgets, demonstrate tasks on that storyboard, then press a button to produce a valid cognitive model predicting how long it will take a skilled user to complete those tasks. CogTool can be used today to baseline your current interface, or compare competitors’ interfaces, and predict how much better your new designs will be.
