UI and UX: where the line sits
UX is the logic of the journey: how many steps lead from opening the app to an order, and where someone might get lost. UI is the visible form of that logic: grid, typography, colour, icons and components. A beautiful UI on top of a confusing flow is useless, while a clear flow wrapped in sloppy visuals erodes trust, especially when the app asks for card details.
That is why ordering "just nice-looking screens" is risky. A designer should start from the business task: taking orders, booking appointments, showing a catalogue or collecting loyalty points. Style comes after that.
What to account for when your users are in Uzbekistan
Many users are on Android phones that differ widely in screen size and power. An interface that looks perfect on a flagship can lag on a budget model because of heavy animation and large images. Mobile internet in the regions can be unstable, so loading and error states need to be clear.
Check the typeface separately: the letters o‘ and g‘ with their apostrophes must render correctly in every weight.
- Two languages: Uzbek and Russian. Uzbek copy is often longer, so buttons and headings must tolerate it.
- Sign-in by phone number and SMS code instead of a long registration form.
- Click, Payme and cash on delivery visible at checkout.
- Large tap targets and readable text: people use apps on the move, one-handed.
- Light images and a cached catalogue to save mobile data.
- A quick way to reach an operator or a Telegram chat.
What good mobile app UI design work includes
A responsible contractor runs the project in clear stages.
If the estimate leaves out empty states and error screens, someone will have to draw them during development, which usually costs more.
- Gathering requirements and mapping user scenarios.
- Wireframes: screen layouts without styling.
- A UI kit: colours, fonts, buttons, fields, icons.
- Mock-ups of every screen, including empty states and errors.
- A clickable prototype.
- Handoff to developers: sizes, spacing, exported assets.
- Support while the app is being built.
What drives the price
The price is set by the volume of work, not by how pretty the result looks: the number of screens, the complexity of scenarios, the platforms (iOS, Android or both), whether a brand book already exists, the amount of animation, the number of revision rounds and how deeply each state is designed.
A freelancer, a small studio and an agency will estimate differently, but ask all of them the same things: what exactly is included, how many revisions are covered and who supports the handoff to developers. Offers cannot be compared by the final sum alone without those details.
How to test the interface before development
Build a clickable prototype and show it to a few real customers. Give them a task, such as "order this product" or "book an appointment", and watch quietly to see where they freeze. Fixing a mock-up is far cheaper than fixing a finished app.
After launch you need analytics: events for screen views, adding to cart and payment. Agree on metrics in advance, such as conversion to order, share of abandoned carts and repeat purchases. Without them you cannot tell whether the app pays off or the budget is simply being spent.
Common mistakes when ordering
Three scenarios repeat most often. The first is copying a foreign app's interface without local habits in mind: it has no Click or Payme and no Uzbek language. The second is design made for a portfolio, with impressive screens that are hard to build and maintain. The third is having nobody responsible for the outcome: the designer hands over files and disappears, and developers interpret them in their own way.
Put it in the contract that you keep the source files, the UI kit and the right to make changes after handoff.
Do you need an app, or is a website enough
If your customers arrive from Instagram and Telegram, a fast mobile website or a bot is often enough. An app is justified by frequent repeat orders, a loyalty programme, push notifications and a catalogue people open regularly.
UI decisions can carry over to a website so the style stays consistent: colours, components, tone of voice. At markdev we build turnkey websites and help work out what makes sense to start with: a site, a bot or an app. Describe your task and we will go through it with you.
FAQ
What is the difference between UI and UX?
UX is the logic and convenience of the user journey; UI is the look and the elements of the interface. You need both, because attractive screens without a clear flow do not bring orders.
How long does UI design take?
It depends on the number of screens, the complexity of scenarios and how fast approvals go. An honest estimate is impossible without a brief; after reviewing your task a contractor should give a plan by stages.
Do I need separate designs for iOS and Android?
Often one design is made that respects the rules of each platform, since system navigation and gestures differ. The decision depends on budget and audience.
Can I start with a website instead of an app?
Yes, if customers come from social media and search. Demand is easier to test on a website, and the design decisions will be useful in an app later.
