Generating… usually about a minute.
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.

Temptation comes in waves. Ride it out. Sprout Wave is a simple Apple Watch utility that helps you resist cravings and impulses using urge surfing — a technique from behavioral psychology. The science is simple: most cravings peak and fade within 60–90 seconds if you don't act on them. Sprout Wave gives you exactly what you need in that moment — a timer, a breathing guide, and a calming visual — so you can ride the wave instead of giving in. HOW IT WORKS 1. Feel a craving. Tap the complication or open the app. 2. Watch the wave rise and fall as you breathe through it. 3. At 90 seconds, check in — did the wave pass, or are you still riding? 4. Reflect honestly. No judgment. Just the next step. WHAT SPROUT WAVE HELPS WITH Eating • Smoking • Vaping • Alcohol • Drugs • Gambling • Shopping • Social Media • Gaming • Caffeine • Anger • Pornography • and more FEATURES — 90-second animated wave timer that visually mirrors a craving: rises, peaks, and drains away — Apple-style breathe in / breathe out guidance with haptic cues — Live heart rate monitoring — a gentle nudge when your HR spikes during a craving — Rotating encouragement messages tailored to your category — Compassionate reset — no shame if you gave in, just the next step — Customizable category list with your own priority order — Watch face complication and Smart Stack widget for instant access — No account. No subscription. No tracking. Just you and the wave. THE SPROUT PHILOSOPHY Sprout Wave doesn't track streaks or show you charts. It exists for one moment: the moment you feel the pull. Small wins grow big change.

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.
