Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Screen plan
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.
Differentiate and validate
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.

App Store description
Compound is the daily protocol tracker for people serious about how they live. Habits, peptides, supplements, bloodwork, mood, sleep, gratitude — tracked together. One daily score from 0 to 100, weighted across what you do (Protocol), what your labs say (Biology), and how you feel (Mind). The number you have in your head, finally on the page. WHAT YOU TRACK · Habits — meditation, training, walking, anything daily · Peptides — BPC-157, TB-500, semaglutide, with reconstitution math built in · Supplements & medications — dose, schedule, cycle · Bloodwork — drop in your lab PDF, we extract every biomarker automatically · Weight & body composition — trend lines, deltas, charts · Mood, stress, sleep — five-second daily check-in · Morning gratitude & evening reflection practices THE COMPOUND SCORE A single 0-100 number that reads everything you log: · 40% Protocol — what you actually did · 30% Biology — what your labs and weight say · 30% Mind — mood, stress, sleep, daily practices When components are missing (no labs yet, no mind data), weights redistribute. The score never gets stuck. THE 14-WEEK GRID 98 tiles, one per day, colored by how close you came to 100. Patterns emerge fast — usually within a week. Tap any tile to drill into that day's logs. PDF LAB IMPORT Drop your last panel from Function, Quest, LabCorp, Inside Tracker — anywhere. The app reads it, extracts every biomarker, matches them to optimal longevity ranges (not just standard ranges). 30 seconds, no typing. THE COACH (ELITE) Every morning, an AI briefing reads your last 30 days and writes 2-3 sentences about what's specifically happening in your data. Not generic advice. Grounded in your numbers. Updates daily, refresh on demand. PROTOCOL LIBRARY Browse curated protocols — Sleep Reset, the ApoB Protocol, Recovery Stack, Cognitive Performance — with full dosing, scheduling, and citations. Adopt the whole stack in one tap or pick what fits. BUILT FOR Founders, biohackers, lifters, longevity-curious. Anyone tracking peptides, taking quarterly bloodwork seriously, or trying to actually see what's working. PRIVACY Your data is encrypted at rest and never shared, sold, or used to train AI models.

Build scope
Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Define the first version
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Set boundaries
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Check the hard parts
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.
