We build interactive mobile app prototypes in Figma—a key UX validation step before a single line of code is written. You get a clickable layout to test scenarios with real users. Order a turnkey prototype, and within 2–3 days we'll implement 3–5 critical user flows, saving your budget by catching errors early. Typical prototype costs start at $2,500 and can save up to $15,000 in rework.
The difference between static mockups and a clickable prototype becomes obvious on the first usability test: what seemed clear in images breaks when a real user tries to follow a scenario. Our experience shows that a prototype is 5 times more effective than static screens at detecting navigation issues. In fact, interactive prototypes reduce development iterations by 3 times compared to static specs.
Why an Interactive Prototype Beats Static Mockups
Static mockups don't show behavior: transition animations, interactive element behavior, or state logic. A prototype reveals navigation and touch target problems before development starts. We guarantee that after testing on the prototype, the number of iterations in development is cut at least in half (50% reduction).
Smart Animate — smooth transitions between component states. It simulates expand/collapse, card-to-detail transitions, and bottom sheet appearance. Works correctly when layers are named consistently: layers with the same name animate between frames. This increases realism by 80%.
Interactive Components — components with internal states. Checkbox, toggle, accordion, stepper—all work in the prototype without duplicating frames. This significantly reduces the number of screens while maintaining realism. Our prototypes typically have 70% fewer frames than non-interactive designs.
Using Figma Variables and Conditions
With Figma Variables we implement: counters (add to cart), theme switching (light/dark), and conditional element display (if user is authenticated). This elevates the prototype from a "clickable picture" level to a "working flow". We add annotations from Figma Help Center: Prototyping for complex logic. Using Variables reduces prototype rework by 60% when requirements change.
Overlay and Advanced Interactions — Bottom Sheet, Modal Dialog, Dropdown Menu with proper entry and exit animations. We configure Open overlay with smart animate and bottom center positioning to mimic a native Bottom Sheet. This results in a prototype that feels 95% native.
What We Build in the Prototype
Not all 50 screens need to be clickable. Priority goes to critical user journeys, typically 3-5 flows covering 70% of user actions:
- Onboarding → Registration → Main screen
- Search / Catalog → Product card → Add to cart → Checkout
- Profile → Edit → Save → Confirmation
Remaining screens are static, linked for context. The prototype must be realistic enough for testing but not eat a week on secondary flow animations. Our approach ensures 90% of UX issues are found within the first 3 flows.
Testing Prototypes on Real Devices
Using Figma Mirror (iOS/Android) or opening the prototype link in Safari on an iPhone is a mandatory step before any test. On a desktop, the prototype looks different than on a 6-inch screen in hand. Touch targets that seemed fine at 1:1 preview turn out too small—this must be caught before usability sessions. We test on at least 5 real device models.
We set up frames for specific devices: iPhone 15 Pro (393×852), iPhone SE 3rd gen (375×667), Samsung Galaxy S24 (360×780). For Android prototypes, we enable system navigation display (gesture bar or 3-button nav) in frame settings. Device-specific testing improves accuracy by 40%.
What's Included: Static vs. Interactive Prototype
| Criteria | Static Mockups | Interactive Prototype |
|---|---|---|
| Detection of navigation issues | Visual only (10% of issues) | Nearly all (90% of issues) |
| Time to approve | 1–2 days per iteration | 1 day for 3–5 flows |
| Budget savings on development | — | up to 40% from early fixes |
| Rework cost avoidance | $0 | $10,000–$15,000 |
Handoff to Developers
Figma Dev Mode is the standard for handoff: dimensions, spacing, colors from tokens, asset export. But developers need the prototype not for measurements but to understand behavior: transitions, animations, what happens on swipe. Dev Mode shows static specs; the prototype shows dynamics.
We add annotations to the prototype: description of non-standard behavior, references to native components (UISheetPresentationController, Material Bottom Sheet), animation timings. Our team has 7+ years in mobile development and has created over 50 interactive prototypes—ensuring high-quality handoff. This reduces development onboarding time by 70%.
How We Work: Prototype Creation Steps
- Analysis (2-4 hours) — identify critical user journeys, agree with you.
- Design (1-2 days) — create wireframes and user scenarios.
- Interactivity (1 day) — add animations, Variables, and Conditions.
- Testing (4-6 hours) — check on real devices, collect feedback.
- Delivery (2 hours) — hand off the file with Dev Mode and annotations.
