Design your app as if you were meeting the customer face to face.

The Interface Is Like the First Handshake

The first screen in an app is like the first handshake between you and the customer. It can be warm, organized, and convey trust, or it can be cold, haphazard, and end the relationship before it even begins.
Design the interface with the user in mind, not the designer. Ask yourself: What does the customer want to see first? How can they get there in the fewest steps? How can I make the experience understandable from the first moment?
The visual interface isn't just about colors and fonts; it's an implicit message telling the customer: We understand you, and we know what you need. This feeling instills an inner comfort that keeps them coming back.
Don't leave the first handshake to the designer's discretion alone; make it the result of a deep understanding of your customers, their behavior, and their immediate needs.

Ease of navigation is like clarity of speech

When you're talking to your customer face-to-face, make sure to use clear language, without complex or difficult terms. The same principle applies to navigation within the app.
Every section should be clear, and every option should be understood by its name, without the need for explanation or guidance.
Customers don't like to "search" for what they need; they like to find it right in front of them. Ease of access to everything means you're speaking to them in a language they understand, just as you would in a face-to-face meeting.
Think of the design as if you were in a session with the customer, explaining step-by-step what they can do. Don't hide behind icons or leave them lost; instead, be their intelligent guide with every click.

The app speaks to the customer in their own language.

When you meet a customer face-to-face, you choose your words carefully and use their language, not yours. This same approach should be translated within the app.
A successful app doesn't use complex technical jargon; it uses vocabulary that the customer can easily understand. Don't burden the user with unfamiliar terms, and don't hide functions behind obscure phrases.
Every word, every sentence, and every button should mimic the user's environment. The more they feel the app is speaking directly to them, the more likely they are to continue interacting.
Clear, straightforward, and simple communication = a comfortable experience, just like real-life conversations.

The app shouldn't overwhelm the customer.

When explaining it to a customer face-to-face, try to keep the concept simple and avoid complexity. That's how the design should be.

Is the user interface confusing? Are there too many steps to complete a simple request? Does the customer feel like they're "learning" how to use the app rather than benefiting from it?

The app should serve, not test the user's intelligence. Good design condenses, simplifies, and makes the experience intuitive from the first moment.
Just as you want your customer to see your company as simple and clear, make your app convey the same message.
