How can you ensure mobile app UI is legible in dark mode?

Use High Contrast Text: Opt for text colors that provide a strong contrast against the background. Adjust Font Size and Weight: Make sure your font size is appropriate for reading in both light and dark modes. Choose Suitable Fonts: Select fonts that are clear and easy to read, even in low light conditions. Implement Dynamic Text Scaling: Allow users to adjust the text size according to their preferences. Provide Ample Spacing: Ensure there is enough space between text elements and other UI components to prevent crowding. Utilize Adaptive Color Schemes: Design your app with adaptive color schemes that automatically adjust based on the selected mode.

In IOS, you can leverage system colours and adapt UI elements to respond to changes in appearance. Use semantic colours for elements like labels and backgrounds, allowing the system to automatically adjust them based on the selected colour scheme. Test the app's UI thoroughly in both light and dark modes to identify any readability issues. Employ system fonts and enable dynamic type to allow users to customise text sizes according to their preferences.

Incorporate dark gray/navy for backgrounds, lighter shades for text & accents in dark mode UI. Limit bright colors for hierarchy & emphasis to avoid distraction.

Use strongly contrasting colors to improve readability. Many factors affect the perception of color, including font size and weight, color brightness, screen resolution, and lighting conditions

As we know the most of people use DarkMode in the app because it's very helpful for eyes and make design app cool but here some tips to ensure if our design is legible with dark mode 1- Avoid use pure black color in BackGround 2- Avoid use pure white colors in fonts 3- Avoid use any dark colors like purple or any other dark

From a QA perspective, here are a few pointers: 1. Opt for dark grey instead of pure black to prevent high contrast 2. Ensure text colors are softer to the eyes, like off-white 3. Use semi-transparency judiciously to reduce harshness 4. Adjust graphics to dark variant.

For Android consider adhering to material theme guidelines and use online tools to create a theme that is accessibility compliant and use tools like accessibility Scanner, accessibility inspector in Android studio etc. to validate accessibility in dark mode.

Contrast and brightness play crucial roles in ensuring readability and usability in dark mode UI design. Adequate contrast between text and background, as well as between different UI elements, is essential for clear visibility and distinction. Tools like Contrast Checker or Color Safe can help assess and adjust contrast ratios to meet accessibility standards and improve user experience. Additionally, managing brightness levels effectively, either through device settings or utilizing dark mode APIs to adapt to ambient light conditions, enhances user comfort and reduces eye strain, maximizing the benefits of dark mode.

Ensure sufficient contrast between text and background elements. In dark mode, text should be light-colored (usually white or light gray) and background should be dark. Use tools like the WebAIM Contrast Checker to verify the contrast ratio meets accessibility standards.

Ensure there's enough contrast between the text and background. The background should be dark enough to show white text. A grayscale color palette that includes shades of black, dark gray, and light gray helps maintain readability and avoids excessive contrast between text and background.

Probably the most important aspect in text tendering is arguably not the font but the space. Be generous on space to allow the text to breathe but also be consistent. Define set margins, paddings and a line height and use them in a consiste manner to creat a rhythm while the user is reading your content.

Opting for sans-serif typefaces like Roboto or Helvetica proves advantageous for their clean lines and readability, especially on the limited real estate of mobile screens. Establishing a coherent typographic hierarchy ensures that users can swiftly navigate through the app's interface, with clear distinctions between headers, subheaders, body text, and other elements. This hierarchy not only aids in organizing content but also contributes to the overall visual appeal and user comprehension.

Typography and spacing are critical aspects of dark mode UI design. Choosing clear and legible fonts is essential, avoiding thin or overly decorative options that may be difficult to read against a dark background. Ensuring an appropriate font size and line height contributes to readability and user comfort, while maintaining a balanced layout. Proper spacing and alignment help create visual separation and harmony between elements, enhancing overall usability and aesthetics. Avoiding excessive use of borders or shadows prevents unnecessary noise and clutter, contributing to a cleaner and more cohesive UI design.

Introduce appropriate line-height, especially for your main body text. A good rule of thumb is to go for 150% of your body text font size, but also consider the particular characteristics of the selected typeface

Plan around on selecting fonts and leave enough spacing not just for dark mode support but accessibility concern. Don't create design that looks nice on a wine bottle label but doesn't flex for screen sizes and dimensions. Remember your user could be changing font sizes for readability

Testing your UI is more important in the development. If you have UI design compare it with the UI design. Test it on your end very tough and be honest and accept and correct the UI. If you can't think the way of user prespective. Then you go for external testers. Always design your UI in figma or any other UI development tool and confirm the design before starting development.

Event based tracking and cursor heat maps for UI-UX testing are truly a thing of the past. The impact that a UI can have on your emotions is often the fastest way to understand the seamless-ness of the user experience and whether you have been able to help the user achieve their objective in the cleanest way possible. Emotion ai based UX testing is now one of the leading ways to understand how user friendly your UI-UX truly is.

Don`t forget to create/mention in a couple of places about your newest dark mode in app. According to researches, most users (79%), don`t get straight away with UI/UX updates in app. That is why it is extremely important to share updates/add to onboarding info about new dark mode in app. Great dark mode experience => higher retention => higher revenue.

After Testing, Remember to Test Again! Even after going live Test the System. Remember to: 1. Always rigorously test your app's UI in dark mode across various devices and screen sizes. 2. Involve users with visual impairments in the testing process to gather valuable feedback and identify potential accessibility issues.

Test the UI on a variety of devices and platforms to ensure compatibility and consistency across different screen sizes, resolutions, and operating systems. Pay attention to how the UI adapts to dark mode settings on various devices and make adjustments as needed.

Make sure you have used the color scheme that suits both themes. If you have some yellow color text, verify the impact of that on both themes. The same goes for any color like that. The UX has to be managed more than the UI, you have to consider every corner case for that to work.

In dark mode, ensure that the size of the text is appropriate for easy reading and there should be a high contrast between the text and UI elements against the background; for example, if the background is dark, use lighter colors for the text and UI elements. Its also useful to provide options to adjust text size and contrast within the app settings.

Design UI components with dark mode in mind. Borders, shadows, and highlights may need to be adjusted to ensure they stand out against a dark background. For instance, using a lighter border for input fields can help them stand out.

Follow accessibility guidelines and consider users with visual impairments. Provide options for users to adjust text size and contrast settings if possible.

Consistency: Maintain consistency across light and dark modes to provide a cohesive user experience. Elements such as navigation patterns, typography, and branding should remain consistent regardless of the mode selected. User Feedback: Gather feedback from users to understand their preferences and experiences with light and dark modes. Use this feedback to make iterative improvements to the app's design and functionality
