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.

Pelvic floor release, done properly. Every pelvic floor app teaches you to squeeze. Almost nobody talks about the opposite problem — the pelvic floor that won't let go. Constant tension down there can mean pelvic ache and pressure, discomfort with intimacy, tampons or examinations, urgency, hesitancy, and pain that nobody can quite explain. Ebb was designed by a fellowship-trained urogynecologic surgeon to teach the half of pelvic floor health the other apps skip: down-training — the deliberate skill of letting go. A release program built for your situation • Tension Reset — for the floor that never gets a day off • Comfort & Intimacy — for discomfort with intimacy, tampons or exams, with optional self-paced dilator companion sessions • Flare-Day Companion — gentle, zero-pressure sessions for endometriosis and chronic pelvic pain days • Rebalance — for chronic clenchers and the over-trained floor Programs progress over weeks exactly as down-training is paced in pelvic health physiotherapy — and adapt to you: sessions that feel easy advance you, sessions that feel hard ease back. Sessions built around your breath • The floor releases on the in-breath. Ebb's breathing circle and gentle haptics pace you through it — eyes closed, phone face-down, music uninterrupted. • Guided sessions take about three minutes. Comfort sessions have no clock and no target: you end them, they count. • Nothing to squeeze. If you catch yourself gripping — that's the exercise. Learn what almost nobody explains • Why a tight floor causes the same symptoms as a weak one — and why more Kegels can be the wrong prescription • The reverse Kegel, properly taught • The jaw–pelvic floor connection and where tension hides • Honest guides to painful intimacy, dilator work, endometriosis and the guarded floor — and exactly when to see a clinician Watch it work Weekly 30-second check-ins chart tension, discomfort and how at-ease you feel — a trend you can show your own doctor or pelvic health physiotherapist. Comfort sessions log a comfort rating that builds its own rising line. Private by design No account. No cloud. No analytics. No tracking. Your health data never leaves your iPhone — export it or erase it any time. Notifications are completely discreet and never mention the pelvic floor. Ebb provides education and relaxation guidance. It does not diagnose or treat any condition, and it does not replace assessment by your own clinician.

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.
