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

Reduce your risk of injury when running. Run faster! AudioStep helps you to run consistently by running to the beat of all your music. AudioStep analyzes your music and adjusts the tempo on the fly. The pitch does not change. No Chipmunks were harmed building this app! You select your BPM (beats per minute) and all your music plays at that tempo. Initially AudioStep was designed to consistently run at 180 steps per minute by matching each step to the beat of the music playing at 180 beats per minute. Eventually, testers found different use for listening to music at different BPM and so we added a slider where you can set your target BPM going from 120 up to 200 BPM. Studies have found that running at 180 BPM reduces the risk of injuries. Why? The slower the cadence, the longer you are in the air and the harder you land. Slow turn over means more impact, which causes more injury. Most non-elite runners maintain a cadence of around 160 steps per minute. Increasing the step count to 180 per minute will reduce your risk of injury. As a side effect it also makes you run faster. While there have been no studies identified to prove this, there is a lot of anecdotal evidence available online. - Normalized volume (all songs use the same perceived volume, no more Taylor Swift being louder than Metallica, they both are now normalized to the same perceived volume) - Runkeeper support - Bluetooth heart rate monitor support with warnings for high and low heart rates - Voice over status updates (distance, time, split pace, average pace, step count). You can set your own update interval as text entry in miles or meters - 5 eq presets (import for Equalizer presets is in the works) to make it sound the way you want (bassbooster, treble booster, u-shape, extrabass and flat) - Sophisticated Beat Detection library by SampleSumo Read more about a personal account on how AudioStep was developed on our blog at blog.audioforge.org Also please note that continued use of GPS running in the background can dramatically decrease battery life.

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.
