The application does not close, so be as elegant as the main branch of your project.

Greet your customers from the screen as if you were opening the branch door yourself.
When a customer enters your app, they don't see walls or meet an employee. They encounter your design, presentation, and department layout. The app is your first welcome, your virtual smile, and your welcoming style. Does the home screen reflect this impression? Does it resemble opening the branch door yourself and welcoming the visitor face-to-face?
Every page in the app should express your care. Every detail should tell the user that they're in the right place. Don't leave things to chance or random design. Instead, think of the app as a complete showroom. From colors to images, from fonts to buttons, every element should carry a part of your business's identity.
Is the design pleasing to the eye? Can you find what you're looking for easily? These questions reflect the customer's experience. It doesn't matter how many hours you've worked on the service or product if it doesn't show up in the app upon first use.
Even error messages or in-app alerts can be elegant, clear, and in a way that doesn't upset the user. It's as if a receptionist politely apologizes and suggests an alternative.
Every process within the app should feel realistic: smooth browsing like strolling through a store's departments, a purchase that feels like a face-to-face meeting with a cashier, and technical support that feels like someone is standing by the customer's side to help them.

Every button in the app is an employee representing your business.
When you're creating an app for your business, think of every element within it as an employee on staff at your main branch. The button the user clicks, the message they receive, and the menu they select from—all of these elements speak for you. Are they up to par with your brand?
Your app never closes, never takes a break, and never delays response time. It's an employee working 24/7, which is why its interface and content must be carefully and meticulously designed. A simple button used to book or purchase should be clear, elegant, and enticing to click, just like an employee's smile welcoming a customer.
The language within the app is extremely important. It's the voice the customer hears. Choose your words carefully, avoiding complexity or ambiguity. Instead of dry, formal phrases, use a friendly tone that makes the customer feel welcome and cared for.
Don't neglect the small details, like the speed at which pages open or the appearance of pop-up windows. Just as the customer notices the cleanliness and order inside the store, he also notices the smoothness of the application and the elegance of its movements.

The customer experience in the app is equivalent to a visit to your physical branch.
What makes a customer return to your store? They'll likely say: the service, the organization, the cleanliness, and the ease of accessing what they need. In the app, things are not much different, and may even be more sensitive. The user doesn't see or hear an employee; they interact with a screen that represents your business. Here, experience is everything.
Every step within the app is equivalent to a physical step inside your branch. When they open the homepage, does the user feel welcome? Do they know where to go? Or do they feel lost, as if they've entered a chaotic place with no clear signage?
A successful app is like a carefully curated showroom. Don't throw everything at the user at once; instead, organize the information intelligently, gently guiding them and showing them what's most important to you without imposing it.
The user interface (UI) and user experience (UX) are two sides of the same coin. One is concerned with appearance, the other with smoothness. Both must be carefully designed to make the customer feel like they're in a familiar, safe, and easy-to-use place.

Don't overdo the offers or effects that distract the user. Just as a store cluttered with offers confuses the visitor, a cluttered app drives the customer away. Thoughtful simplicity is more effective than clutter.
Also, don't forget that in-app service must be complete. Don't let the customer reach a point only to be surprised by a malfunction or missing step. A disjointed experience erodes trust, even if the product is excellent.
The app is your digital branch, welcoming thousands of visitors without any staff. Make it clear, polite, and convenient, so every user feels valued and appreciated, just as if they visited you in person.
