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

You already have a great todo app and calendar on your phone; they're called Reminders and Calendar. The problem is, they don't talk to each other about your free time! Reminder Wrangler fixes that. It takes the todos in your Reminders app and schedules them into free slots on your Calendar — automatically, in the background. When a todo conflicts with a meeting, it moves. When you don't get to something, it reschedules to the next day. You never have to open Reminder Wrangler to make this work. Just keep using Calendar and Reminders the way you already do. WHY THIS MATTERS A todo list without a time slot is just a list of things you feel bad about not doing. When your todos show up on your calendar between meetings, they become real plans. You can see what's realistic for today and what isn't. That's the difference between "I have 20 things to do" and "I have three things to do before lunch, and time to do them." BUILT FOR HOW YOUR BRAIN ACTUALLY WORKS If you have ADHD — or if you've just noticed that trying out five productivity apps doesn't actually make you more productive — Reminder Wrangler was made for you. It doesn't replace anything. It doesn't ask you to learn a new interface or change your workflow. It works entirely through the Calendar and Reminders apps you already know. One less app to get distracted by. HOW IT WORKS • Create reminders in the Reminders app like you normally would — no need to pick a time • Reminder Wrangler finds free slots on your calendar and schedules your todos there • If a todo conflicts with a meeting or another reminder, it gets moved automatically • If you don't complete a todo, it reschedules to your next available free time • Runs in the background — no daily check-ins required Reminder Wrangler is a quiet utility that does one thing well: it keeps your todos close to now, on the calendar you're already checking.

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.
