Dark Mode and Theme Toggle

[Image]

Dark mode options have become a common expectation across fintech apps, offering visual comfort and personalization. For product designers and managers, the challenge is ensuring dark mode maintains readability, contrast, and brand consistency while providing easy control.

Fintech Dark Mode Theme & Toggle Testing uses a design stack of UX metrics: usability, satisfaction, and intent to measure how effectively the theme supports visibility and preference-based interaction. This approach replaces subjective opinions with measurable insights.

With these findings, designers and managers can make informed design decisions, prioritize improvements, and demonstrate the impact of changes on business outcomes. For example, testing Coinbase’s dark mode toggle revealed strong appeal but weaker usability, showing where toggle placement and contrast ratios could be improved to ensure smooth transitions and visual consistency.

Define Goals for Your Dark Mode & Theme Toggle

A fintech dark mode & theme toggle experience should balance user needs like comfort, accessibility, and control with business goals such as retention, satisfaction, and brand consistency. Users want to choose the visual experience that feels best for their eyes, environment, and workflow, while businesses aim to provide a modern, flexible interface that reduces visual strain and keeps users engaged longer. Measuring theme toggle interactions ensures accessibility and preference are supported without compromising clarity or performance.

**Audience:**

This concept was tested with mobile banking consumers in the United States who explored Coinbase’s visual theme controls, including its dark mode settings. Participants were asked to toggle themes, navigate with dark mode active, and share impressions of readability, comfort, and control.

**User Needs
**As a user adjusting visual themes in a financial app, the five most important needs would be:

1. The theme toggle should be simple to find and activate, with clear labeling and immediate feedback. (Toggle should be Usable)

2. Both light and dark modes should maintain strong readability, contrast, and visual clarity. (Modes should be Accessible)

3. The visual styling should feel modern, polished, and aligned with user preferences for comfort or aesthetics. (Styling should be Desirable)

4. Switching modes should be fast and seamless, requiring minimal taps or navigation. (Modes should be Efficient)

5. Users should feel in control of the environment that best supports their eyes and focus, particularly during long sessions. (Controls should be Empowering)

These five ensure theme settings feel intuitive, comfortable, and inclusive, helping users create an environment that fits their needs and reduces fatigue.

Business Goals
Here are the five most important business goals for a fintech dark mode & theme toggle:

1. Increase User Comfort & Retention – Reduce eye strain and improve long-term usability, keeping users active and engaged.

2. Enhance Accessibility Compliance – Ensure visual modes support users with different visual needs or sensitivities.

3. Improve Brand Perception – Offer modern, customizable themes that reflect innovation and user-centric design.

4. Support Contextual Use Cases – Provide visual modes that work well in bright, dim, or variable lighting environments.

5. Collect Preference Insights – Track theme usage patterns to inform UI, color, and product evolution strategies.

These goals help the business improve satisfaction, support accessibility, and reinforce a modern brand experience through customizable visual themes.

Choose Metrics to Test Your Dark & Light Mode Toggle

For SoFi’s dark mode and theme toggle experience, a design stack of three UX metrics was chosen to measure how effectively the interface supports accessibility, ease of use, and personal preference. This stack — Usability, Satisfaction, and Intent — was established by mapping user needs directly to measurable outcomes:

• Usable & Efficient → Usability

  Switching themes should feel simple, intuitive, and immediate. Usability measures whether participants can find and operate the theme toggle without friction, and whether the transition feels seamless.

• Accessible & Empowering → Satisfaction

  Theme options should make the interface more comfortable and personalized. Satisfaction captures whether participants feel the experience improves readability, reduces strain, and offers meaningful control over the interface.

• Desirable → Intent

  A well-designed theme toggle should motivate continued use. Intent evaluates whether participants express interest in using dark mode (or switching between themes) as part of their ongoing experience with the product.

Establish Hunches to Direct Your Testing

In fintech apps, visual presentation strongly shapes how users interpret trust, risk, and complexity. Dark mode can feel modern, premium, and focused — but may also add friction if contrast, readability, or feature visibility suffers. Coinbase’s heavy use of dark mode sets a sleek tone, but its theme toggle and the surrounding UI elements may influence how users perceive control, clarity, and comfort within an investing environment.

Turn Hunches into Test Questions

Turning these metrics into participant questions transforms design assumptions into measurable signals. Each metric uses a specific question type paired with a clear example from Coinbase’s dark mode settings experience:

• Usability **(Average success across multiple click directives)**

  Question type: Multi-task click test.

  *Example:*
 “Where would you tap to turn on dark mode?” followed by
 “Where would you tap to adjust appearance settings such as light, dark, or system default?”
 (Success rate is averaged across tasks)

[Image]

• Satisfaction **(Likert scale of satisfaction)**

  Question type: Satisfaction scale.

  Example: “Overall, how satisfied are you with how easy it is to locate and change appearance or theme settings in Coinbase?”
 (Very Dissatisfied → Very Satisfied)

[Image]

• Intent **(Multiple-choice selection between preferred actions)**

  Question type: Action preference.

  Example: “Which of the following actions would you most likely take after reaching this settings page?”
 (e.g., Turn on dark mode, Switch back to light mode, Set to system default, Explore other settings, Exit without changes)

Calculate UX Metric Scores from User Feedback

For Coinbase’s Dark Mode Theme & Toggle, we measured how effectively users could locate, understand, and adjust the app’s appearance settings. The design stack for this test included Usability, Satisfaction, and Intent — a blend of behavioral clarity and emotional alignment tailored to users customizing their visual preferences in a financial app. Each metric score was calculated on a 0–100% scale using the standard benchmarks below:

• Very Good = 90% and above

• Good = 70%–89%

• Average = 50%–69%

• Poor = 30%–49%

• Very Poor = below 30%

Once the individual UX metric scores are calculated, the average of those scores are used to determine the overall score for the user experience.

Coinbase’s Results

Usability **(83% — Good):**
 Participants found the Dark Mode toggle easy to operate and appreciated that the setting was clearly labeled. The interaction required minimal steps and felt predictable, though some users wished the appearance preferences were placed more prominently within the menu.

Satisfaction **(58% — Average):**
 Emotional response to the experience was mixed. While the toggle worked as expected, users felt the page offered limited visual feedback or thematic context. Several described the interaction as “plain” or “utilitarian,” lowering overall satisfaction.

Intent **(54% — Average):**
 Participants showed moderate interest in returning to this setting. Some preferred relying on system-level dark mode rather than adjusting it manually, while others wanted more customization options before committing to using it regularly.

Taken together, these metrics paint an Average overall experience (65%), highlighting that Coinbase’s Dark Mode toggle is easy to use but not yet compelling or discoverable enough to drive stronger satisfaction or repeat engagement.

Draw Signals from Your Design Stack

Here’s how signals were surfaced from the Coinbase dark mode test results by following these five steps:

1. Focus on poorly scoring metrics

[Image]

Coinbase’s theme toggle experience earned an overall score of 65% (Average), with Usability performing well (83%), while Satisfaction (58%) and Intent (54%) fell noticeably behind. These lower emotional and motivational scores point to a key issue: users can operate the toggle, but don’t feel particularly satisfied or compelled to use it. The main signal is that the feature functions correctly but fails to deliver the clarity, polish, or control expected from a modern fintech app.

2. Identify patterns across metrics

[Image]

The pattern indicates that although the toggle is technically usable, the experience may feel incomplete or underwhelming. Users seem to understand how it works, but the lack of visible theme states, limited previewing, or minimal visual feedback likely contributes to weaker satisfaction. Likewise, the low Intent score suggests users don’t feel motivated to adopt or revisit theme settings—implying missed opportunities in comfort, accessibility, or personalization. This shows a gap between functional execution and emotional resonance.

3. Determine if user needs are being met

[Image]

Usable: Met — The toggle is easy enough to find and operate.

Accessible: Partially met — Light mode is clear, but lack of mode previews or contrast reinforcement may hinder broader accessibility.|

Desirable: Not met — Users aren’t delighted; styling feels basic rather than modern or polished.

Efficient: Met — Switching is quick, though users may want more context or immediate visual confirmation.

Empowering: Not fully met — Limited sense of customization or environmental control reduces the feeling of ownership.

4. Compare outcomes to your business goals

Increase User Comfort & Retention: Partially achieved — Functional, but not delivering meaningful visual relief or long-term comfort.

Enhance Accessibility Compliance: Partially achieved — Some readability strengths, but lacks depth for visually sensitive users.

Improve Brand Perception: Not achieved — Basic execution misses the modern, user-centric polish expected in a leading fintech app.

Support Contextual Use Cases: Partially achieved — Light mode works, but no adaptive guidance or previews for varying environments.

Collect Preference Insights: Not supported — Limited interaction and low intent reduce meaningful user behavior signals.

**5. Surface signals & establish a direction
**
Signals derived from the data:

• Strong usability but weak emotional engagement reveals a utilitarian implementation lacking refinement.

• Satisfaction and Intent deficits suggest users don’t see clear value or benefit in switching themes.

• The toggle feels more like a settings checkbox than part of a thoughtful, comfort-oriented visual experience.

• Accessibility gaps—such as lack of preview or contrast cues—may quietly degrade trust and inclusivity.

Direction based on business context:

To strengthen satisfaction, intent, and overall visual comfort, consider:

• Adding live previews or inline visual representations of Light vs. Dark modes.

• Introducing microcopy explaining the value (“Reduce eye strain in dark environments”).

• Improving visual polish, transitions, and contrast indicators to make the experience feel modern and intentional.

• Offering adaptive or contextual recommendations (“Switch to dark mode in low light?”).

• Testing contrast ratios and readability more rigorously to support accessibility compliance.

Based on the signals and design direction, we created an updated version of the design with the expected UX metric improvement:

The signal is clear: Coinbase’s theme toggle works, but doesn’t resonate. Elevating clarity, previews, and emotional polish will transform it from a functional switch into a meaningful, comfort-driven feature users actively choose.
