Interaction design and prototyping tool for web and mobile apps
Create hi-fi prototypes and simulations. Avoid rework. Boost user adoption
From clickable prototypes to functional simulations
Create from clickable prototypes to fully-functional simulations, without typing a single line of code. We provide a full range of tools, so that you can focus on creating delightful user experiences. Testing through simulations will reduce rework and boost user adoption.
Bring your interaction design to a superior level
Design full interactions of your web and mobile products, from the navigation to the last details of the user experience: advanced interactions, animations, transitions, interactive UI elements. Launch easy to use products and boost user adoption.
Web interactions
Design web experiences with a full range of interactions, animations and transitions. Create anything from simple links to advanced interactions.
Mobile gestures
Choose from a ton of gestures that allow you to rotate, tap, swipe, scroll and pinch your way through your mobile app prototype.
Free UI Design with no limits
Design your UI assets for free, without any restrictions on number of projects. Enjoy all UI design features, from the vector design tool, the pen tool, to pathfinders and more.
From low to high fidelity
With a single tool, you can cover the entire cycle of designing your products. Start by conceptualizing with low-fidelity wireframes, iterate, and validate your designs with high-fidelity prototypes and even interactive simulations.
Forms and data in motion
Design, prototype and simulate fully-functional forms and data grids-lists, and test them instantly without writing a single line of code.
Bring your prototypes to life in a click
Visualize your web and mobile prototypes, while you design them. Simulate prototype behavior while you design. Use our Emulator and Viewer App to test your prototype live on any iPhone, iPad or Android device.
Design better experiences together
Validate early and often. Allow all your stakeholders to test and review your prototype, leaving no room for misunderstandings. Improve communication between teams, putting them all on the same page.
Share and get feedback
A single click lets you publish your prototypes and invite all project stakeholders to give feedback early on.
Team prototyping
Multiple users can work on or edit the same prototype simultaneously. Our version control system tracks the changes.
