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.

Where Was I? – Automatic Time & Location Logger Where Was I? is the perfect tool for tradespeople, field service professionals, or anyone who needs an accurate, hands-free log of exactly where they’ve been and how long they were there. Say goodbye to manual timesheets and guesswork. Where Was I? automatically tracks your location in the background, smartly recording only the places you actually spend time. It’s intelligent enough to know the difference between a stop at a job site and a stop at a traffic light. Key Features Smart Background Tracking: Set it and forget it. The app seamlessly logs your stops while you go about your day. Total Location Control: Give locations custom names, adjust their detection radius, or set "ignore" zones (like your home) so you only record what matters. Merge Locations: Combine nearby or overlapping spots into a single detection area. Any historical visits will automatically merge into the new location. Easy Export & Sharing: Need to bill a client or submit a timesheet? Share an individual location visit, or export your entire location history as a CSV file in seconds. Privacy First & Battery Friendly Your Data Stays Yours: Your location history never leaves your device unless you choose to share it. Zero Ads or Trackers: The app contains no advertising or hidden third-party tracking code. Your privacy is assured and completely in your control. Battery Efficient: Visit tracking is highly optimized so it won't drain your battery. (Note: For automatic tracking to function correctly, you will need to grant the app "Always" location permission).

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.
