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

Take back your Messages inbox with Spam Text Blocker by Nomorobo. Nomorobo’s award-winning technology is now built for text messages and helps filter spam and scam SMS and MMS from unknown senders, so you spend less time dealing with junk and risky links. Stay focused on real conversations while suspected spam gets filtered out before it distracts you. KEY FEATURES • Filter spam and scam texts from unknown senders • Reduce distractions from promotional and fraudulent messages • Simple setup in a few steps • Built with Nomorobo’s 10+ years experience fighting unwanted communications HOW IT WORKS Spam Text Blocker runs as an iOS Message Filter. • The initial filtering happens on your device. • For some messages, iOS sends a non-identifying request through Apple’s message filtering services to help determine whether a message looks like spam. • We never receive info that directly identifies you (like your phone number, Apple ID, or contacts). • The result is used only to classify messages as junk or allowed. PRIVACY We’re built for spam protection, not data collection. Spam Text Blocker filters on-device and may use Apple’s message filtering services to send a non-identifying request to Nomorobo’s servers for classification. We do not receive your phone number, contacts, or any other information that directly identifies you. Data is used only to provide and improve spam filtering. You can check out our privacy policy here: https://www.nomorobo.com/pages/privacy and our terms of service here: https://www.nomorobo.com/pages/privacy#tos SUPPORT If you have any issues, please email our customer support team at [email protected].

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.
