What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.
States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.
Hypothesis: Contractors need faster repeat invoices more than more templates.
First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.
The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.
Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

SitPose is a calm posture coach that watches your back while you work. Prop your phone to your side, start a session, and SitPose uses the front camera and on-device pose detection to notice when you slouch or crane your neck - then gently nudges you back upright with a sound, a spoken cue, or a haptic. When you're done, you get a quiet summary of how you sat. PRIVATE BY DESIGN • 100% on-device. Apple's Vision framework analyzes each frame in memory. • No video is ever recorded, saved, or uploaded. • No account, no sign-in, no tracking, no servers. MADE TO FEEL CALM, NOT NAGGY • Calibrate to your own good posture — alerts are based on your baseline, not a one-size-fits-all rule. • A grace period, so a quick reach for your coffee never nags you. • Separate sensitivity for neck and torso, with clear on-screen gauges. • Choose a gentle sound, a spoken reminder that names the area to fix, or silent haptics for shared offices. • Stand-up reminders to get you moving on your schedule. • Auto-pauses when you step away, so your good-posture score stays honest. HOW IT WORKS iOS can't use the camera in the background, so SitPose runs as a focused, screen-on work session. That keeps your stats clean and meaningful instead of vague all-day numbers. For long sessions, prop your phone on a stand and keep it plugged in. Sit well.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
