How do you know if your app's UX is good or bad?
The answer is: The GIRLFRIEND Test.
LET ME EXPLAIN.
If your girlfriend isn't in tech, send her your app and ask her to use it.
Don't explain anything.
Just watch.
If she doesn't understand what your app does...
Or doesn't know what to do after signing up...
Your UX is bad.
But if she immediately understands what your app is about...
And knows exactly what to do after signing up...
Your UX is good.
