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

Feature spec

Goal: Send a clear invoice after finishing a job.

  • Add a client, line items, a due date, and payment instructions.
  • Preview the total before exporting a PDF.
  • Keep an editable draft if export fails.

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

Elixr is a supplement tracker with absorption science built in. It flags the supplements in your routine that cancel each other out — and shows you the study behind every note. Most trackers just buzz at you at 9am. Elixr knows that calcium blocks iron, that zinc and copper compete for the same pathway, and that coffee cuts iron absorption — and it tells you when you've put two of them in the same time slot. FLAGS COMBINATIONS THAT CANCEL OUT 15 research-backed interaction pairs, each with a one-tap link to the study on PubMed. Plain language, no jargon, and a clear note that this is information — not medical advice. TIMING TRAVELS WITH EACH SUPPLEMENT Set the conditions once: with food, on an empty stomach, needs a fat-rich meal, away from coffee and tea. Assign it to a time of day and Elixr checks the fit — something that needs food, dropped into a slot without it, gets flagged right on your Today screen. Start typing and Elixr recognises 61 common supplements and fills in their usual conditions for you. REMINDERS THAT FOLLOW YOUR REAL SCHEDULE Every day, chosen weekdays, or every few days — with start dates, end dates, a pause while you take a break, and as-needed items that never nag. Each notification lists exactly what's due. Mark everything taken, or snooze 30 minutes, without opening the app. HOME SCREEN WIDGET Small, medium or large. See what's still due, tick off a single supplement, or mark a whole time slot done — straight from the home screen. CONSISTENCY, NOT GAMIFICATION Seven days, a month, or a year at a glance: days completed, your completion rate, and a calendar where every day reads as complete, partial, skipped, missed or still pending. Tap any day to see what you took — and correct it if you forgot to log something. No streak to break, no badges, no guilt. SYNCS ACROSS YOUR DEVICES Your schedule and history sync through your own iCloud account. Set it up on iPhone, find it on iPad. No Elixr account, no sign-up, no password. READABLE FOR EVERYONE Full VoiceOver support and Dynamic Type throughout. Available in English, German, Japanese and Korean. WHAT ELIXR DOESN'T DO No ads. No analytics. No tracking. No third-party SDKs of any kind. No subscription — you buy it once. Nothing you enter leaves your own devices. Elixr helps you organise what you already take. It is not medical advice — talk to your healthcare provider about what's right for you.

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.

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.
