Nobody had tested the app like a real user

This is an extremely common problem. The team knows the product so well… it stops seeing the obvious problems.

The developer knows the shortcuts. The designer knows the screens. The client already knows the logic. So everything feels "obvious". Except for a new user… nothing is.

Where the disasters start

And that's often where the disasters start. The important button is invisible. The flow is incomprehensible. The texts say nothing. The navigation feels weird.

But nobody on the team notices. Why ? Because they no longer truly discover the app. They already know it.

And honestly, that's a huge trap in mobile.

The user has none of your context

Because an app must work for someone who :

• knows nothing about the product,
• arrives with no context,
• barely reads,
• decides extremely fast.

According to the Nielsen Norman Group, 5 user tests are enough to reveal 85% of an app's major usability issues. Five.

The best test is also the simplest

The best user tests are often very simple : watch someone use the app… without helping them.

And immediately, tons of problems appear : hesitations, misunderstandings, missed taps, abandonment, frustration.

The most interesting part is that many of these problems feel "obvious" in hindsight. But as long as you stay inside your own product logic… you don't see them.

Simplicity comes from observation

That's also why apps that feel simple are often the result of huge amounts of user observation. Simplicity isn't accidental. It usually comes from a very fine understanding of real behaviors.
