Build a clickable app prototype with Sketchflow

Describe the journey before generating screens

Luke’s September 2025 walkthrough uses Sketchflow to create an interactive prototype with frontend screens and backend workflows. The description also covers templates, custom images and HTML export. The title’s speed claim and five-minute opening describe the recorded example; they do not establish a measured 100-fold improvement for another project.

1. Open https://sketchflow.ai and describe the user, main task, required screens and the information passed between them. Choose one complete journey you can click through before adding secondary features.
2. Generate the initial prototype and compare the screen sequence with that journey. Note which transitions represent real interactions and which only illustrate a future backend action.

Customise pages, workflows and visual direction

The walkthrough edits workflows and pages at 2:05, chooses styles at 3:20 and explores templates at 4:40. An attractive template can supply a visual starting point without answering the product’s specific interaction requirements. Keep the app task visible while changing its appearance.

1. Follow the main action from the first screen to its result, checking navigation, form inputs and the information carried forward. Revise a broken or missing transition before polishing unrelated pages.
2. Choose a style or template that fits the content and inspect readability, hierarchy and small-screen layout. Keep meaningful labels and controls clear instead of letting generated imagery replace the information a tester needs.

Generate assets and inspect the exported demonstration

Custom-image generation appears at 7:15 and sharing or exporting at 8:59. The useful deliverable is a prototype another person can understand and navigate. Exporting HTML does not independently establish live authentication, durable storage or a production-ready backend behind the simulated flow.

1. Generate the required images and check their fit with the actual interface, including text, proportions and cropping. Revisit the complete journey after adding the assets.
2. Export through the demonstrated HTML route and open the exported result. Click through the same sequence, noting anything that behaves differently from the editor preview and the functions still represented only as a prototype.

The takeaway

Judge the prototype by whether it communicates and demonstrates the intended journey. Preserve the brief and remaining functional questions alongside the export for the next build stage.
