🏆 Our Verdict
Principle earns a 4.6/5 Noizz editorial rating. It covers high-fidelity interaction prototyping, motion and behaviour, not just static screens, which is the part worth judging it on: motion and interaction shown, not described, and testable with users before any code. The trade-off to weigh is prototypes are throwaway work. It is a fit for designers proving how an interaction should feel before engineering builds it, and a poor fit for anyone whose requirement sits outside that shape.
