About the technology
What ProtoPie does
ProtoPie is an interaction design tool for creating realistic, high-fidelity prototypes without building production code. In ProtoPie Studio, teams combine layers, triggers, responses, variables and formulas to model touch, gesture, motion and state changes. The result is a clickable prototype that communicates behaviour, not just screen layouts.
Prototypes it supports
ProtoPie is suited to products where timing and physical response matter. Experts use it for:
- Mobile app flows with gestures, transitions and dynamic content
- Connected-device and automotive interface concepts
- Voice, sensor and motion-driven interactions
- Usability tests for responsive product behaviour
It can also demonstrate micro-interactions, onboarding, navigation systems and complex component states before a production team commits to implementation.
Studio and Connect
The core workflow runs in ProtoPie Studio, with support for imported design assets, variables, formulas, conditions and reusable components. ProtoPie Player lets people review prototypes on supported devices, while ProtoPie Connect links prototypes to external hardware, software or data sources. Familiarity with Figma, Sketch, Adobe XD, design systems and interface handoff helps experts move cleanly from concept to testable experience.
When companies need help
Companies often bring in freelance ProtoPie expertise when a static prototype cannot answer important product questions. This is common during early concept validation, stakeholder reviews, usability research or the preparation of a complex handoff. In Germany, specialists may support automotive, consumer electronics, industrial and digital product teams, working remotely or alongside local design and research groups.
What strong experts deliver
A strong specialist turns an interaction idea into a clear, testable prototype. They plan states and edge cases, choose the right triggers and responses, organise variables, and keep the file understandable for others. They also document device requirements, explain limitations honestly and adapt prototypes to the people who will test them.
Choosing the right specialist
Look for work that shows more than polished screens. Ask how the expert handled gestures, interruptions, conditional logic, sensor input and changes across devices. A useful review includes the prototype structure, the testing goal and the decisions it enabled. For German teams, clarify language expectations, working hours, device access and collaboration with product, research and engineering stakeholders before the engagement starts.
Frequently asked questions
What clients ask us most about ProtoPie — answered in short.
ProtoPie is used to create realistic interactive prototypes for mobile apps, websites, connected products, automotive interfaces and hardware concepts. It can simulate gestures, animation, sensor input, conditional behaviour and changing interface states without requiring a production build.
ProtoPie usually offers deeper control over dynamic behaviour, formulas, variables, sensors and physical interactions than a standard Figma prototype. Figma remains useful for interface design and collaboration, while ProtoPie is often selected when teams need to test how an experience responds over time or across devices.
A strong ProtoPie expert often understands interaction design, motion principles, usability testing and design systems. Experience with Figma, Sketch, Adobe XD, mobile interface patterns, hardware inputs or front-end implementation can make collaboration and handoff more effective.
A small flow may only require familiarity with core triggers and responses, while a connected-device or automotive concept calls for deeper ProtoPie expertise. The right level depends on the number of states, external inputs, test devices and stakeholders involved, not simply on the size of the prototype.
Yes. ProtoPie projects can be handled remotely when the team shares source files, test objectives, device requirements and review times clearly. On-site sessions can still help with hardware testing, research workshops or close collaboration with German product and design teams.
ProtoPie can connect to external systems through ProtoPie Connect, making it possible to explore interactions involving hardware, sensors, software or live data. The exact setup depends on the devices and interfaces involved, so an expert should confirm technical constraints before promising a particular demonstration.
Review whether the ProtoPie file represents the intended states, timing, gestures and edge cases rather than only its visual polish. Ask to see how the prototype is organised, how it behaves on target devices and what research or product decision it is designed to support.
Before starting with ProtoPie, clarify the prototype's purpose, audience, target devices, source design files, interaction scope and review process. Also confirm whether the deliverable is a demonstration, a research instrument, a stakeholder presentation or a handoff aid, because each goal calls for a different level of realism and documentation.
