I spent $400 on ads before realizing my onboarding was broken
Decent CTR, decent signup rate. Most of those signups never reached the feature that makes the app worth using.
Found out by watching real users go through the flow on screen recordings. Not analytics. Actual footage.
One tester spent almost a full minute on the step right after signup. The CTA I thought was obvious. She hovered, clicked the wrong thing twice, came back, hovered again. A full minute. On one button.
Analytics said "users drop at step 2." The recordings showed why. Fix took 20 minutes.
Found three things across four sessions. Fixed them. Ran ads. Conversion went up enough that the unit economics changed.
If you're spending on ads before you've watched real people use your product, you're paying to confirm something's broken, not to fix it. It's a weird kind of expensive.
Watch five real people go through your flow before you spend anything on acquisition. You'll find something. It'll be uncomfortable. Fix it first.
(I built TestFi for this real testers, screen recordings. Mentioning it in case it's useful, not the main point.)
