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.

AI-GENERATED OPPORTUNITY HYPOTHESES

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

Provide enhanced visualizations and more types of feedback (e.g., sound cues).

Assumption to check: Limited signal feedback options

Validate with people who use this workflow before building.

Hypothesis 2

Add insights and trends based on historical sync data.

Assumption to check: No historical data analysis

Validate with people who use this workflow before building.

Hypothesis 3

Implement multi-device sync capabilities.

Assumption to check: Single device sync only

Validate with people who use this workflow before building.

Hypothesis 4

Allow users to customize metrics and display settings.

Assumption to check: Minimal customization options

Validate with people who use this workflow before building.

App Store description

WatchWave can perfectly simulate the signals of 6 radio stations around the world. No matter where you are, you can receive radio signals to calibrate your radio watch and clock. The first WaveTurbo, Radio watch not be restricted by the signal area! Even a 2-Band radio watch can use the WaveTurbo to sync radio signals anywhere. We use Swift programming language to make sounds through the speakers, and it is incredible to realise the perfect simulation of radio signals. We call this simulation technology "WATCHWAVE SIMULATION TECHNOLOGY". We have well-designed the interface of the App, which simplifies the operation process and makes it convenient to use. Features: - Perfect Multi-Band 6 simulation With the simulation technology of our research, we achieved the radio wave signals of WWVB(United States), MSF(Europe), DCF77 (Europe), BPC (China), JJY40 (Japan), JJY60 (Japan). - WaveTurbo Radio watch not be restricted by the signal area! Even a 2-Band radio watch can use the WaveTurbo to sync radio signals anywhere. - Support all kinds of radio watches and clocks Multi-Band 2, 3, 4, 5, 6 radio watch or clock can be calibrated. - Tutorial guide We have built a quick tutorial for you to get started quickly. We also provide multiple case tutorials and online video tutorials. - No ads We consider advertising to be annoying, so we haven't added any ads to our well-designed interface. - Support iPhone and iPad Based on the iPhone, we redesigned the software interface for the iPad. If you have any questions during use, please contact us through the feedback in the App. Or send an email to: [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.
