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

This app is a pretty scientific experiment in deep photo editing. At RNI we wanted to make our photos look more special with less effort and more fun. So we created RNI Flashback — an app that works like film not like an app. Using Flashback is simple. You just press the button and it generates editing options for you. And then you choose the best one. Because you’re the boss. Unlike other apps, RNI Flashback has no pre-defined filters. Instead it mixes virtual 'chemicals' and creates a unique look every time you press the button. This transforms digital medium making it more true to life and more refreshing. Flashback is created for everyone. But professional photographers and aficionados familiar with shooting film will especially love it. Because Flashback works more like photographic film rather than like digital software. Unlike any other existing software, Flashback uses real film data and simulates the response of real film layers by light when processing digital colours. This results in a completely unique output which can't be achieved in traditional image editors with conventional tools. Some of its looks can be weird, some can render skintones too red. But some will be just absolutely fabulous, making for film-like colour harmony and colour separation, far beyond what’s achievable in any other piece of software you have ever tried. Experience RNI Flashback now. Bring custom artistic flair into your photos and never get bored again. -- #RNIFlashback Tag your photos with #RNIFlashback for a chance to get featured in RNI’s official newsletter, blog and Instagram @reallyniceimages.

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.
