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

ReplayCam - the time shift video camera. “How was that?” This app turns your iPhone into a time shift camera that can instantly display whatever it just shot. You’d normally have to pay big bucks for an on-the-fly replay device. Now all you need is ReplayCam on your iPhone! TIME SHIFT ReplayCam enables you to play back up to 60 seconds of whatever you’ve just filmed while you continue to film. Use it to check your golf swing or practice your party tricks leading up to the festive season, or as a drive recorder in your car, or if you’re a researcher, to monitor an experiment and never miss that vital moment. There’s no end to the ways it can be useful! Simple operation using just Record and Play buttons enables easy repeat checking so that you can focus 100% on whatever you’re doing. REPLAY In the Replay mode, you can select clips for looped playback, or display live visuals in rows to compare and check movement. You can also crop and save whatever clips you want to Camera Roll, post them to social media, or use them in other apps or on a PC or Mac. Key features: - Replay of up to 60 seconds of whatever you’ve just filmed with your iPhone’s camera (Time Shift view) - Easy switching between front and back cameras - Simultaneously save a Time Shift video to Camera Roll while playing it - Export Time Shift video to external display device - Looped playback of selected clip (Replay view - Loop Playback function) - Save selected clips to Camera Roll - Auto lock can be disabled for longer filming - Record clips that play smoothly even on iPhone 4 by reducing quality (Recording Priority mode) Notes: - Recording frame rate: 32 fps from iPhone 4S onward, 17 fps for iPhone 4 (approx. 24 fps in Recording Priority mode) - Frame rate and possible recording length may vary according to handset usage status. - Recording length and Time Shift replay length can be customized.

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.
