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.

Reach us at [email protected] or http://www.myfitnesssync.com/support Syncing your Apple Health app everyday with Health App to Strava Sync allows you to use the Strava app and your account at strava.com to view your fitness data. Select from multiple sources like your iPhone, Apple Watch, Garmin watches and other fitness devices, or other walking, running, and workout apps that sync with your iPhone and Apple Health. The app will try to sync your Apple Health data to Strava in the background multiple times per day. - Auto-sync may take a few days to work, as iOS controls this process based on user behavior. For privacy reasons, iOS will not run an auto-sync if your phone is locked - this can cause auto-sync delays. - Your Apple Watch does not stay up-to-the-minute in sync with Apple Health on your phone. This can cause the data on your Strava dashboard to be slightly out of sync with your Apple Watch. If you need your Strava dashboard to be exactly in sync with your Apple Watch please launch the Apple Activity app on your phone before syncing with our app. Launching the Activity app forces your Apple Watch to sync with your phone. Launching the Activity app before syncing with our app is not required because by the end of the day your Apple Watch will be in sync with Apple Health and all of your data will be synced to your Strava account. We want hear from you!! If encounter any issues or would like to request a new feature please email [email protected] or click the "App Support" button in the App Store. HOW DOES IT WORK Data is synced using 3 easy steps. 1. In the Health App to Strava Sync app, sign into Strava.com using your account credentials. 2. Pick the fitness fields you want to sync with your Strava account. 3. Click the "Sync Now" button to start syncing your Apple Health data with your Strava account DISCLAIMER: We are not affiliated with the mentioned companies in any way.

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.
