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

By analyzing HRV and Stress along with additional data, SweetBeat HRV provides a deeper dive into health and provides insight into what activities you engage in that effect the health metrics you care about. IMPORTANT: SweetBeat requires external hardware: A tested Bluetooth Low Energy Heart Rate Monitor or KardiaMobile 6L hand held heart rate monitor. While other manufacturers wrist worn devices work well for heart rate, their wrist worn heart rate monitors are not accurate enough for HRV and so are not supported. The iWatch is not supported. •Please visit https://www.sweetwaterhrv.com/healthsensors.shtml for a list of compatible Heart Rate Monitors devices. SweetBeat HRV will also import your Apple Health app data (SDNN, Resting Heart Rate, Average Heart Rate) that is collected by the iWatch or other devices authorized to store metric in the Health app. This data is for viewing purposes only and is not used in any HRV calculation. SweetBeat has two main components: •Monitor Stress •HRV for Training/Recovery •KardiaMobile 6L 3 Minute CheckUp Monitor Stress: With SweetBeatHRV, you can see your stress levels in real time, giving you the ability to take action to reduce stress. If your chosen stress threshold is reached, SweetBeat’s Relax screen prompts you with a deep breathing screen that includes calming images. •Stats: The stats screen more widely referred to as the “geek” screen, shows all the metrics being measured. If using the HealthPatch, the user can view the additional provided metrics. •Graph: The graph screen shows a real-time building graph of your heart rate from RR Intervals. Turning the phone 90 degrees counter-clockwise will bring up the graph in landscape. •Export RR Intervals: SweetBeat provides RR interval export capability along with other raw data files in .csv format. HRV For Training: In competitive sports, improved performance is often affected by alternating periods of intensive training with periods of relative rest. SweetBeatHRV measures HRV, an objective measure of your body’s response to each workout and provides training recommendations based on the morning reading. KardiaMobile 6L 3 Minute CheckUp: With SweetBeatHRV and the KardiaMobile 6L hand held device, you can measure your HRV with a 3 minute countdown timer. This type of session can be used conveniently any time of the day when you want to check your HRV and stress levels. The KardiaMobile 6L hand held device is convenient and eliminates the need of a heart rate monitor chest strap. Please note that the KardiaMobile 6L device is the only KardiaMobile device that is presently supported by SweetBeat HRV. SweetBeat Features: •Customize your Relax screen images with your favorite pictures. •Track your heart rate recovery after exercising. •Save and upload sessions to your secure SweetWater Health account at www.BeatHealthy.com. •Email your RRs and session data for personal analysis off-line •View your Apple Health data with trend lines

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.
