Every bad screen has a culprit

Learn UX laws, metrics and formulas by solving short detective cases. Each one takes about two minutes.

The cases

The Vanishing Checkout: Orders fell overnight. Follow one hungry customer from opening the app to paying, and find every place they give up.
The Money Mix-up: Support tickets are piling up. Follow one person paying their rent, and find each point where they get confused.
The Stuck Setup: New teams sign up, then go quiet. Walk through setup with one new team, and help them reach the moment the product clicks.
The Abandoned Cart: Shoppers fill their carts, then disappear. Follow one shopper to the last step, measure the leak, and find what drives them away.
The Quiet Classroom: Learners join full of hope, then fade away. Spend a week with one learner, and find out what gets in their way.
The Bad Review: Ratings are sliding, and the team keeps arguing. Bring evidence, not opinions, and settle it.
The Trial Nobody Trusts: Free trials are flat and refund emails keep coming. Find out what people are afraid of, then prove the fix works.
The Late Aha: Downloads are strong, but most people leave before they see why the app is good. Find the moment that matters.
The Exit Door: Cancellations are climbing, and the team keeps trying to block the door. Find out what actually keeps people.
