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

Simple PDF editor for iPhone and iPad. Scan a paper document with your camera, or open a PDF from Files, Mail, or any app. Add text, sign it, fill in the form — then send it back. No subscription. No cloud. No account. One purchase covers iPhone, iPad, and Mac. Works fully offline. —— WHAT YOU CAN DO —— • Scan paper documents with the camera — several pages become one PDF. • Open PDFs from Files, Mail, Messages, or any app that can share. • Add text anywhere on the page — type it, then place it with your finger. • Sign with your finger — draw, type, or reuse a saved signature. • Fill existing PDF forms — text fields, checkboxes and dropdowns, detected automatically. • Reorder, rotate, delete and add pages. • Send the finished PDF anywhere — Files, Mail, Messages, or another app. —— MADE FOR YOUR THUMB —— Open a document. Tap what you want to change. That's it. No tutorial, no nested menus, nothing to set up. —— PRIVATE BY DESIGN —— Everything happens on your device. Your documents are never uploaded, and there is no account to create. —— WHO IT'S FOR —— • Anyone who needs to sign a form and send it back, right now • Freelancers and consultants signing contracts on the move • Parents filling in school and medical forms • Anyone tired of paying every month just to edit a PDF —— ABOUT ADDTOPDF —— Made by Mantra Factory — a small studio building simple, honest apps that respect your time. Pay once, use it forever. Requires iOS 14 or later. Works on iPhone and iPad.

These are generated suggestions, not verified review quotations. Check current App Store reviews and speak with users before treating a possible gap as a requirement.

Hypothesis 1

Expand to support more file types like DOCX, TXT.

Assumption to check: Limited file type support

Validate with people who use this workflow before building.

Hypothesis 2

Allow users to import files from cloud services like Google Drive, Dropbox.

Assumption to check: No cloud storage integration

Validate with people who use this workflow before building.

Hypothesis 3

Introduce basic PDF editing features like annotations or merging.

Assumption to check: No editing features for PDFs

Validate with people who use this workflow before building.

Hypothesis 4

Implement more detailed progress indicators and notifications.

Assumption to check: Minimal user feedback during conversion

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.
