Our prototypes look fine in the tool, but they feel sluggish on real phones during usability tests. What should I check in a prototyping tool?

“Good for collaborative design and straightforward interactive prototypes.”

“Supports variables and conditional interactions.”

“Provides mobile-device preview through its mobile application.”

“A good starting point for testing navigation and common user journeys.”

“Supports complex conditional interactions.”

“Offers advanced gestures, inputs and sensor-based interactions.”

“Supports testing on actual mobile devices.”

“Particularly interesting for testing realistic mobile interactions.”

“Strong conditional logic and variables.”

“Supports complex branching workflows.”

“Useful for testing forms, dashboards and data-driven interfaces.”

“Particularly suitable for logic-heavy prototypes.”

“Axure's documentation provides concrete examples of how conditional interactions work, including form validation and IF/ELSE scenarios.”
