Today, it is estimated that more than 5 billion people have mobile devices, and over half of these devices are smartphones. Mobile landscape is changing rapidly, and users have high expectations about the mobile experience. Designers strive to create mobile app designs that not only meet users’ needs but also provide a delightful experience. In this article, we will cover the common screens that almost any mobile app has, as well as share some design tips for every screen. But before we dive into details about mobile screens, we will discuss the key difference of mobile UI design.

Mobile UI design specifics

As you know, mobile experiences are highly focused due to their screen size. Since you cannot put as much content on a mobile screen as on a desktop, both the content and features we provide on mobile devices should always be prioritized according to the needs of the target audience.

Splash screen

We all know the importance of the first impression in interpersonal communication. A first impression is what a person thinks of you when they first meet you. It takes just a glance for someone to evaluate you when you meet for the first time. These first impressions set the tone for the relationship that follows. The same rules apply for digital experiences.

The first screens that users see when they start using your product create the first impression. And the very first screen that most apps show to their users is a splash screen. The role of a splash screen is to create a feeling that the app loads fast. Splash screens are usually minimalistic and show only a logo and a product’s name. It’s recommended to show splash screen no longer than 3-5 seconds otherwise the users will think that loading takes too long.

Onboarding screens

Onboarding is a human resource term borrowed by product designers. The purpose of onboarding is to introduce first-time users to the product and get them ‘up-and-running’ with it. In many mobile apps onboarding screens are dedicated to getting users familiar with product features or benefits of using a product. Some apps try to educate users on how to interact with mobile UI—they wrap quick tutorials or contextual guidance into the onboarding experience to familiarize users with common operations. No matter what type of onboarding you choose to use, it’s important to remember that onboarding shouldn’t feel like a roadblock for the first-time users. Make sure it feels natural to the user and allow the users to skip onboarding if they want to start using the app.

Home screen

Home screen is a screen that users see when they complete onboarding. This screen acts as a starting point for the user journey. Home screen design can vary dramatically depending on the purpose of the product, but there are a few elements that almost any home screen has:

  • Menu. The home screen should help users navigate to the different parts of your product. When it comes to designing a navigation experience, it’s better to use existing navigation patterns. Mobile UI usually has either tab bar navigation or a hamburger menu.
  • Search input field. The search field is a typical element of eCommerce apps. It acts as a shortcut and allows users to search for a particular product.
  • Relevant content. Depending on the nature of a product, the home screen can have a feed with items or any other types of content that will be valuable for users.

When it comes to designing a home screen, it’s essential to consider the information density. The information on the home screen should be highly prioritized. Don’t try to put everything you have on the home screen otherwise the screen may look cluttered.

Empty states for “No content”

Content is what provides value for most apps. It’s the primary reason why people are using them — for the content. Thus, it’s critical to consider how to design places in the user journey where a user might not have content yet. Such places are known as empty states, and empty states shouldn’t look…well, empty.

An empty state is a natural point to inject some onboarding to guide users along. Instead of leaving it blank, you should use it efficiently — to educate and guide.

Search results screen

Search is an essential element of mobile UI. When it comes to designing search, it’s vital to remember a few fundamental rules:

  • Use autocomplete to reduce the interaction cost. As users start typing something in a search input field, your app should provide the most relevant suggestions to eliminate the need to type the entire search query, but also to reduce the probability of zero-search results (when no items found).

  • Decide what will be a default order for the search results. For example, if you design a search results page for an e-commerce app, you need to decide whether the output should be sorted by best match/price/delivery time.
  • Allow users to filter search results. Filtering is especially important for eCommerce apps where the user can have dozens of different options in search results.
  • Allow users to bookmark items. In eCommerce apps, users might want to save a particular item in order to complete the purchase later.

  • Always consider the “No results” state. What screen will your users see when the app does not have any matching results. “No results” screen shouldn’t act as a dead end. Instead of showing a blank page with a quick note “No results,” you should design a screen that guides users and shows what they can do next.

Profile screen

Many mobile apps ask users to create an account before accessing the experience. Users have a special place in mobile apps where they see and customize their account settings—profile screen. Here are a few things to remember when designing profile screen:

  • Allow users to change their personal information and customize the preferences (i.e. customize the notifications they want to receive).

  • Allow users to sign out. ‘Sign out’ is one important feature that many mobile apps should introduce on profile screens. This feature allows a user to logout from the app and sign in using a different account.

Product-specific mobile UI screens

Ecommerce apps

Since the main objective of eCommerce apps is to sell products to their users, such apps have four screens that are relevant to the product purchase flow:

  • Products catalog screen. This screen provides a list of items the company offers for sale. Depending on the nature of a product, the visual layout can be either a list of a grid view. The list view works better for products like appliances because the users want to read text description to make a decision while the grid view works better for apparel where users rely on items visual appearance when making a decision.
  • Product details screen. Product details screen contains essential information about the item, offers photos or illustrations of a product and provides a call to action button ‘Add to cart.’ The purpose of this screen is to help users decide whether they want to buy this product or not. That’s why it’s vital to provide enough details about the items to simplify the decision-making process.
  • Cart checkout. The checkout screen is a final screen that users see before they buy the product. This screen must provide all information about the product and final price (including product delivery) and the shipping details (the address for the delivery as well as its cost).
  • Purchase confirmation screen. This screen acknowledges that the user ordered selected items. It’s recommended to provide order number on this screen as well as information about the delivery (i.e. the message like “Your items will arrive on Sep 22, 2019 will help users understand when they should expect the parcel).

Social media apps

Since the primary purpose of social media apps is communication, the app experience is built around delivering valuable information to users in a timely manner:

  • Feed. Feed is a constantly changing list of events. It’s an essential part of any social network app. Every item of the feed should be designed for quick scanning (remember, users don’t read, they scan!). The feed should be optimized for vertical scroll—users should feel comfortable when digesting the information.

  • Friends/contacts. Friends/contact screen presents user’s contacts in a list. Typically this list is sorted by the name in alphabetical order, but some apps can prioritize the list by the frequency of interaction (i.e. the frequent contacts go to the top of the list). Usually, every item in this list has an avatar, name and short description. It’s worth it to include search field on this screen to simplify the process of finding relevant content.


When it comes to product design, it’s vital to consider all pages/screens a part of the user journey. By doing that you will design screens that will be aligned with user expectations and streamline the process of interaction with your product.
