Ways to Improve user experience in Mobile App Design process

  1. Avoid Sign-In Walls

When designing a mobile app, it's crucial to consider the user experience, especially when it comes to the sign-in process. A sign-in wall, which forces users to register or login prior to they can use the app, can cause friction and lead to user abandonment. To mitigate this issue, it's recommended to follow these guidelines:

  • Evaluate the necessity of registration: Only ask users to register if it's essential for accessing core features of your app. Delay the sign-in process as much as possible, allowing users to experience the app before prompting them to sign up.

  • Provide a taste of the app experience: Allow users to explore the app through a guided tour or introductory content before asking them to register. This way, they can understand the value proposition and become more likely to commit to the sign-up process.

  1. Designing a Good Onboarding Experience

Onboarding is a crucial phase in the mobile user experience, as it sets the foundation for user retention. The goal of onboarding is to showcase the value your app provides. One effective strategy is contextual onboarding, where instructions are provided only when the user needs them. Here are some recommendations:

  • Interactive tour with progressive disclosure: Take inspiration from apps like Duolingo, which pairs an interactive tour with progressive disclosure to guide users through the app's functionality. This approach makes learning and exploring the app more enjoyable and discoverable.

  • Empty states for guidance: Implement empty states, which are screens that guide users on how to use the app when their default state is empty. Even though the initial onboarding procedure is only one step, guiding consumers via empty states reassures them that they are on the correct route.

  1. Don't Ask for new account setup Information Up Front

Requiring users to provide extensive set-up information during the initial launch of an app can create friction and lead to user abandonment.

Instead, design your app to work out-of-the-box for the majority of users. Only prompt for necessary configuration or personalized settings when users express a need or desire for them.

  1. Avoid Asking for Permissions Right at the Start

Requesting permissions at app launch, like sign-in walls or upfront set-up processes, should be performed only when needed for the fundamental functioning of your app.

Users may be more inclined to grant permissions if they understand why your app needs access to specific features or data. Prompt users to accept permissions in context, when they attempt to use a feature that requires those permissions.

  1. Make Your App Appear super - Fast and properly Responsive

The speed of loading is critical for a good user experience. Users expect quick and responsive apps, and slow loading times can lead to frustration and abandonment. Consider the following strategies to optimize loading speed:

  • Concentrate on loading content in the visible area: Load enough content to fill the screen when a page opens, and continue loading additional content in the background as users scroll. This approach engages users with initial content and makes them less aware of ongoing loading processes.

  • Provide clear loading indicators: Avoid leaving users with a blank or static screen during loading. Instead, use loading spinners and progress bars to indicate that the app is processing information. For longer loading times, display a progress bar to give users an idea of the waiting duration.

  • Offer visual distractions: To keep users engaged while waiting, provide visual distractions such as animations or interesting elements. Be mindful not to overuse animations, ensuring they remain enjoyable and unobtrusive.

These strategies collectively optimize the loading experience and give users the impression of a fast and responsive app.

  1. Skeleton Screens

Skeleton screens are temporary placeholders that mimic the layout of a page and gradually load content.

They provide users with the perception of a fast and responsive app by filling the screen immediately and replacing placeholders with actual content as it loads. Skeleton screens can enhance the user experience during loading processes.

  1. Optimize Content for Mobile

Content is a significant component of mobile app design, and it needs to be easily digestible for users. Consider the following aspects when optimizing content for mobile:

  • Make text readable and legible: Choose a font size that is easy to read on mobile screens (generally larger than 16 pixels). Select a clear font family with sufficient contrast between the text and background. Avoid all caps text and limit the length of text lines to around 30-40 characters for improved readability.

  • Use HD-quality images and proper aspect ratios: Ensure that images in your app are of high quality and suitable for HD screens. Images should be displayed in the correct aspect ratio to avoid distortion or stretching.

  • Optimize video content for portrait mode: Given the increasing popularity of video content, it's important to optimize videos for portrait mode since a majority of users hold their devices in this orientation. Consider adapting your video content and player to provide an optimal viewing experience in portrait mode.

By focusing on these content optimization strategies, you can enhance the readability, visual appeal, and engagement of your mobile app.

I hope this breakdown provides a more detailed and technical explanation of the mentioned pointers. Let me know if you need further clarification or assistance with any specific aspect.

  1. Design for Touch

Designing for touch interactions is crucial for mobile apps since users primarily interact with their devices through touch gestures. Here are some considerations for touch design:

  • Design for fingers, not cursors: Keep in mind that users will be using their fingers to interact with your app, so make sure the touch targets are large enough to be easily tapped. The MIT Touch Lab suggests a minimum touch target size of 10x10mm to ensure accurate and comfortable interaction.

  • Consider the thumb zone: Since many users hold their devices with one hand, take into account the natural thumb zone for easier access to interactive elements. Place frequently used or primary actions within the easy reach of the thumb to enhance usability.

  • Provide feedback on interaction: To create a more engaging and responsive experience, provide instant feedback when users interact with UI elements. Visual cues such as highlighting a tapped button or using animations can confirm that the user's action was recognized.

  1. Humanize the Digital Experience

Creating a human-centered and personalized experience can significantly enhance user satisfaction. Consider the following approaches:

  • Personalization: Tailor the app experience based on user preferences, behavior, and location. Offer personalized content, recommendations, or special deals that align with the user's interests and needs. This can foster a stronger connection and make users feel valued.

  • Delightful animation: Use delightful animations sparingly to add an element of surprise and delight to the user experience. However, ensure that animations remain clear, unobtrusive, and do not hinder the app's usability.

  1. Optimize Push Notifications

Push notifications can be a valuable tool for engaging users, but they must be used judiciously. Here are some optimization strategies:

  • Push the value: Ensure that your push notifications deliver valuable and relevant content to users. Personalize the notifications based on user preferences and behaviors to increase their effectiveness and avoid being perceived as spam.

  • Timing and frequency: Consider the timing of push notifications and avoid sending them during inconvenient hours. Peak mobile usage hours, typically from 6:00 pm to 10:00 pm, can be an optimal time for sending notifications. Also, avoid overwhelming users with excessive notifications within a short period to prevent annoyance.

  • Use multiple channels: Instead of relying solely on push notifications, consider utilizing other communication channels such as email, in-app notifications, or news feed messaging. Different channels can be used based on the urgency, type of content, and user preferences.

  1. Adapt Mobile Design to Emerging Markets

When expanding your app to emerging markets, it's essential to understand and accommodate the unique challenges and preferences of users in those regions. Consider the following factors:

  • Poor internet connectivity: In many emerging markets, internet connectivity may be slow or intermittent. Design your app to handle low bandwidth and intermittent connections by allowing offline access, caching data, and minimizing the size of content to ensure smooth performance.

  • Limited data availability: Users in emerging markets often have limited access to affordable data plans. Optimize your app to minimize data usage, provide control over downloading content, and offer transparency on data consumption to help users manage their data effectively.

  • Limited device capabilities: Low-cost smartphones with limited storage and processing power are prevalent in emerging markets. Ensure your app is compatible with such devices and optimize its performance to provide a smooth user experience.

  • Consider local aesthetics: Tailor your app's design to align with the cultural aesthetics and preferences of the target market. Localize your app by incorporating region-specific design elements and hiring local designers to ensure cultural relevance.

By considering the specific challenges and preferences of users in emerging markets, you can adapt your mobile app design to provide a seamless and optimized experience for a broader audience.
