Validate the actual phone experience before committing a sprint. Describe the feature, shape tappable mobile screens, and turn the approved direction into a working iPhone and Android app.
You have a hypothesis about what users want. Instead of writing a PRD, waiting for prioritization, and hoping the sprint delivers in time — build a working prototype in minutes. Put it in front of users. Get real feedback. Then decide if it's worth engineering time.
"A dashboard where sales reps can see their pipeline, filter by stage, and click into deal details." That's your entire spec. Mistflow asks a couple of clarifying questions, builds a plan, and creates a working app. No wireframes, no design handoff, no sprint grooming.
Your stakeholders don't want screenshots in a presentation. They want to click through a real app. Send them a live URL. Let them use it. The feedback you get from a working prototype is 10x more valuable than feedback on wireframes.
Stakeholder says "add a filter by date range"? Ask for the change and publish the new version. The prototype evolves with the feedback. No waiting for the next sprint.
The prototype isn't a throwaway. It's real Next.js code in a GitHub repo. When the team decides to build the feature for real, engineers have a working reference implementation. No re-interpretation, no lost-in-translation.
"I prototyped three feature ideas in one afternoon. Two of them tested well with users and went straight into the roadmap."
