What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
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.
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.

The Pulse Oximetry app lets you take control of your respiratory health with a feature-packed yet beautifully simple tool designed to help you track, monitor, and understand your breathing and oxygen levels. Best of all, you don’t need to sign up for an account or pay for a subscription. Just connect your Bluetooth pulse oximeter[1] and start gaining insights right away. Important Information - A Bluetooth pulse oximeter (sold separately) is required. The app works seamlessly with many of the most popular devices on the market. See the complete list at: www.appinlights.com/pulseoximetry/ - This app is not certified or approved by any regulatory agency and shall not be used for medical diagnosis. It is intended for educational, instructional, and research purposes only. - Alarm conditions generated by the app shall not be considered medical emergencies, but should always be reviewed to ensure user safety. - The Pulse Oximetry app never collects personally identifiable information. Why Choose the Pulse Oximetry App? Whether you’re managing asthma, cystic fibrosis, or COPD (including chronic bronchitis and emphysema) or simply keeping a closer eye on your health, this app gives you the tools to make smarter decisions about your well-being. With the ongoing concerns of COVID-19, staying informed about your respiratory health has never been more important. This app helps you stay on top of your respiratory wellness by harnessing the data from your Bluetooth pulse oximeter[1] and turning it into powerful insights. With easy-to-read visualizations and comprehensive review tools, you can track trends, spot changes, and better understand your respiratory health. Pulse Oximetry is built to work with over 50 supported devices[1] (with more added regularly). That means you can switch pulse oximeters without switching apps — and without losing your valuable history. Your entire health record stays with you, all in one powerful app. Plus, you can easily export your data to Apple Health[2] for seamless integration into your wellness routine. Powerful Features Designed for You - Monitor View: Real-time display of all key measurements in one clear, easy-to-read screen - Advanced Graphs: Detailed line charts for every tracked parameter to spot trends at a glance - Smart Alarms: Customizable alerts that go beyond simple tones, giving you peace of mind - Flexible Recording: Capture sessions from 2 minutes to 10 hours, at 1-second intervals - Personalization: Choose between light or dark mode, and set international date/time formats - Apple Health Integration: Sync your recordings directly into Apple’s Health app[2] - Detailed History: Review spot checks and long recordings with rich data insights - Flag & Highlight: Mark important measurements for future reference - Custom Date Ranges: Focus on exactly the data you care about most The Pulse Oximetry app puts control back in your hands with an intuitive design, unmatched device compatibility, and powerful tools for tracking respiratory health. Whether you’re a patient, caregiver, or researcher, it’s everything you need in one place. [1] The app requires a compatible Bluetooth pulse oximeter to perform measurements. Bluetooth pulse oximeters are sold separately. For a complete list of supported devices go to https://www.appinlights.com/pulseoximetry/supported-devices.html [2] The app supports exporting SpO2, heart rate, perfusion index and respiratory rate to Apple’s Health app. Not all pulse oximeters measure perfusion index and respiratory rate. Please check your device's literature for supported parameters. **Note: The app can be installed on 3rd Generation and newer iPads, but because the screens of these devices have a 4:3 aspect ratio, as opposed to a 16:9 aspect ratio of compatible devices, the app is not guaranteed to look or function correctly on iPads.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
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.
