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

We wanted to create this app as intuitive as possible. We want you to be able to focus on your workout and not bother with counting or anything else. How to: First: Set your Tempo. You have four numbers/counts. They are always in the same order. 1. Eccentric/DOWN - you lowering the weight e.g. Squat from standing to the bottom. 2. Bottom/HOLD - you pausing at your lowest position. 3. Concentric/UP - you standing up with the weight. 4. Top/HOLD - you fully extended/standing with the weight. Second: Set where you want to start the movement. In a Squat or a Bench Press you start from a standing or extended position. Therefore your counts will start with the „DOWN" command. In a Deadlift or Pull up you have to lift the weight or pull yourself up first! Therefore your counts will start with the „UP" command. The starting phase number will be highlighted in green. Third: Set your Sets/Reps/Rest Here you will see the time under tension for each set and for the total workout. That’s it! Easy peasy lemon squeezy! Pro Tips: „SKIP“ if you don’t manage to fulfill your reps in a set, just hit „SKIP“ and the set ist done. The „Rest Time“ you set before will automatically start after hitting „SKIP“. On the Pause screen you will see your actual set and reps. Varying Reps in a workout Let’s say you don’t want to do the classic 5 x 12 Reps. Something more fancy like 7 - 11 - 15 - 11- 7 Reps. Just set your Reps to „15“ your highest rep number of the workout and then just „SKIP“ every set after you did your target reps. Acoustic and optic output: Mute or don’t mute ;-) You will hear the commands like this: DOWN and UP with up to three seconds will be seen or heard as DOWN-DOWN-DOWN or UP-UP-UP. From a four second count it will be like this: DONW - 2 - 3 - 4 or UP - 2 - 3 - 4 The „HOLDs“ either BOTTOM or TOP will always be just seen or heard as „HOLD“ no matter how long you want to hold.

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.
