A developer receives mockups, but the animations don't match the specification — a familiar situation. We refine prototypes in Adobe XD to an interactive state, ready for testing on real devices and handoff for coding. With over 5 years in mobile prototyping and 50+ completed projects, our team ensures high quality.
A clickable prototype allows you to identify UX errors before development begins: check touch targets, plan transitions and animations, test on a real device. This reduces rework during the layout stage by 40% and saves up to 3 working days for the development team. We use Component States, Auto-Animate, and Stacks for rapid component creation. For example, a button with Default, Hover, Pressed, and Disabled states — one component, no artboard duplication. This speeds up revisions by 3 times.
Why a Clickable Prototype in Adobe XD Is Effective
Transitions between screens, loading states, and errors — all of this should be tested before code is written. An animated prototype in the tool allows you to simulate the full user journey: from registration to making a purchase. On a real device, issues with touch targets and text readability that are not visible on desktop are identified. As a result, the developer gets a precise specification of animations and transitions, reducing the number of iterations. A 2023 UX study shows teams using prototyping reduce development time by 30–50%.
Auto-Animate Speeds Up Prototyping
Auto-Animate is a feature that creates smooth morph animations between two artboards with identically named objects. For example, expanding a product card: the element smoothly enlarges, changes color, and moves. Setting it up takes seconds — just set easing and duration. This is 3 times faster than creating animation in After Effects or Keynote. The official Adobe XD documentation describes all parameters, available at helpx.adobe.com/xd/help/auto-animate.html. With Auto-Animate, a single designer can prepare a prototype in 2–3 days instead of a week.
Handling Missing Conditional Logic
Indeed, XD does not support conditional logic or numerical variables like Figma Variables. A cart flow requires a separate artboard for each state. For data-driven prototypes this is inconvenient; for navigational ones, it is insignificant. Solution: we use a state table and document all scenarios separately. For example, for a cart we create artboards "Empty cart", "Cart with item", "Cart with error". The developer receives a description of the logic for transitions between them. This covers 95% of mobile prototyping tasks.
How We Create a Prototype: Step-by-Step Process
- Scenario analysis — identify critical user journeys (not all screens in sequence).
- Build a component system — Button, Card, Input with Component States.
- Assemble artboards and set up Auto-Animate for key transitions.
- Test on a real device via the XD mobile app.
- Export specifications via Share for Development and hand off to development.
What Is Included in the Work
- 15–25 artboards with animations for 3–5 flows (Splash, Onboarding, Login, Main screen, Detail screen, Cart).
- Documentation: description of transitions, component behavior, loading/error states.
- Training for your team on how to open the prototype on a device and make revisions.
- Post-delivery support for 2 weeks.
- Export of assets in SVG/PNG and specifications for iOS (PT) and Android (DP).

UX/UI Design for Mobile Apps: Why a Figma Layout Doesn't Guarantee a Ready Interface
A designer sends a layout—beautiful, with gradients and custom components. The developer opens it and realizes: the button is 36pt, the tap target is 20pt. On an iPhone SE, it's physically impossible to press with a thumb. The bottom sheet covers content when the keyboard appears. Navigation is built against the native iOS model. Apple will reject the app, or users will leave within a week—depending on how lucky you get with the review.
We have been designing mobile UX/UI for over 5 years and have seen hundreds of such situations. During this time, we have designed and helped launch 30+ mobile apps—from fintech products to social networks. You don't need to guess whether the design will pass App Review or Google Play—we embed platform requirements from the first screen. We'll assess your project in one day, contact us.
Mobile UX/UI is not an adaptation of web design. It is a separate discipline with specific platform constraints: safe area, touch gestures, UIViewController lifecycle, Activity state management.
Why Can't You Ignore Human Interface Guidelines and Material Design 3?
Apple HIG and Google Material Design 3 are not aesthetic recommendations. They are documented user expectations formed by years of using system applications. Expectations confirmed by user experience research on mobile platforms (User experience design).
HIG defines: minimum tap target 44×44 pt, safe area insets for notch and Dynamic Island, standard gestures (swipe back on iOS, back gesture on Android 10+). Ignoring safe area is a common mistake. safeAreaLayoutGuide in UIKit and safeAreaPadding in SwiftUI exist precisely for this. A designer who doesn't set safe area margins in Figma guarantees a bug during development.
Material Design 3 introduced Dynamic Color—the color scheme is generated from the user's wallpaper via MaterialTheme.colorScheme in Jetpack Compose. An app that ignores dynamic colors on Android 12+ looks out of place. This is not critical for niche products but is noticeable in mass-market apps.
The most painful platform guideline inconsistencies we encounter on projects:
- Custom navigation on top of system navigation. iOS users expect swipe back from any point on the left edge of the screen. A custom
NavigationController without interactive gesture breaks this. Android users expect the system back button—a custom back button in the left corner does not fully replace it.
- Modal windows instead of navigation push. Bottom sheets are appropriate for actions, not for navigating content.
- Missing haptic feedback.
UIImpactFeedbackGenerator on iOS is not decoration but part of the interface response. Buttons, swipes, and confirmation actions without tactile feedback feel broken.

How to Get the Most Out of Figma?
The Figma Variables API has changed the workflow. Design tokens—colors, typography, radii, spacing—are stored as variables and exported directly to code via figma-tokens or style-dictionary. This eliminates manual value transfer and desynchronization between design and implementation. Practice shows: Figma Variables speeds up asset handoff to development by 2–3 times compared to static frames, and using design tokens reduces code transfer errors by 60%.
Auto Layout with wrap and spacing between elements allows building components that behave like flex containers. A developer opens a component and sees not a static artifact but a description of behavior at different content sizes.
Component Properties—variants, boolean toggles, instance swaps—enable building a full design system right in Figma. A button with 4 states (default, hover, pressed, disabled), 3 sizes, and 2 icon variants is one component, not 24 frames.
Figma Prototype with Variables allows creating an interactive prototype with real state: showing how the screen changes with different variable values. This is no longer just a "clickable layout" but a full UX testing tool.
How to Benefit from Prototyping and UX Testing Before Development?
The most expensive mistake in a mobile product is to develop a feature, release it, and discover that users don't understand how it works. A Figma prototype at the testing stage costs zero development hours. Redoing a finished screen costs days. Testing a prototype before development begins reduces the number of fixes by 80%.
For usability testing, we use Maze (task testing on a prototype—the user goes through a scenario, we get heatmaps and mis-click rates) or direct sessions via UserTesting. Key metrics are task completion rate and time on task, not "like/dislike."
A/B testing on mobile is harder than on web: the App Store doesn't allow UI changes without an app update. Therefore, it's important to test hypotheses on a prototype before release, not through production experiments. According to research, fixing a bug found on a prototype costs 10 times less than after production release. And average task completion time increases by 40% after proper UX optimization during prototyping.
Why Are Animations Critical for Interface Perception?
Animations in mobile apps are feedback. An element doesn't appear instantly—it transitions to the desired state over 200–350 ms. This gives the brain context to understand what happened.
- iOS:
withAnimation in SwiftUI, UIViewPropertyAnimator in UIKit for interactive animations with interruption capabilities. Spring animations with dampingRatio are the basis of most Apple system transitions.
- Android:
AnimatedVisibility, animateContentSize, Crossfade in Compose. MotionLayout for complex scenes with multiple transformations.
- Flutter:
AnimationController + Tween, Hero animations between screens, Lottie for After Effects exports. Lottie is especially effective for onboarding illustrations and empty states.
The key constraint is 16 ms per frame (60 fps) or 8 ms (120 fps on ProMotion devices). Animations must run on the GPU via CALayer/RenderThread, not on the CPU via layoutSubviews. Profiling via Core Animation instrument in Xcode is a mandatory step before releasing animated screens.
Why Is Accessibility Not an Optional Feature?
VoiceOver on iOS and TalkBack on Android are used by up to 15% of users—this statistic is confirmed by accessibility research described in Accessibility (Wikipedia). In absolute numbers for a large app, this is thousands of people. Additionally, App Store rejections due to accessibility occur, though rarely.
Minimum checklist:
- All interactive elements have
accessibilityLabel
- Text contrast ratio at least 4.5:1 (WCAG AA)
- Dynamic Type is supported—the interface doesn't break at maximum font size
- VoiceOver focus flows through the screen in a logical order
SwiftUI automatically generates an accessibility tree from component semantics. UIKit requires manual setup of accessibilityTraits, accessibilityHint, and grouping via shouldGroupAccessibilityChildren.
