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.

Get time trial results to your runners on the day! Timing Mate is the reliable, intuitive way for running clubs to time-trial, handicap, and chase-style races with a single timing official. Record finishers, manage bibs, and export results entirely offline. No accounts, no Internet, no personal data leaves your device. Built for 5K time trials, club handicap races, cross-country events, track sessions, and any athletics race where one volunteer with a phone needs to capture every finish accurately. Key Features - Standard time trials & handicap races: Choose the format when you create the event. Standard mode runs the master clock from Start Race. Handicap mode records each runner's personal start time, with the gun firing automatically on the first start so the leader is always at 0:00. - Pre-load competitors: Add runners by bib, gender and age group before the race so taps during the event capture finishes, not data entry. Add latecomers on race day, mid-race if needed. - Haptic split feedback: Press SPLIT and feel an instant vibration so you can keep your eyes on the finish line, not the screen. - Flexible bib assignment: Tap a competitor tile to assign the next finisher in real time, or rapidly tap SPLIT during a cluster and assign bibs afterwards. - Cluster recovery with "?": Can't identify one runner mid-cluster? Tap the purple "? Skip" tile to mark that slot and keep assigning the bibs you do know. Resolve "?" entries from the Results page when you have a moment. - Missed-start recovery (handicap): Tap REC START for any runner whose bib you didn't catch crossing the start line. A pending strip appears so you can match each anonymous start to a bib once the rush is over. - Edit individual start times: Long-press a handicap competitor to adjust their personal start to an exact mm:ss elapsed from the gun. - Reorder finishers safely: Switch to Reorder mode for up/down arrow controls. Position numbers update live, so accidental drags can't break your results. - Mark DNS / DNF / DQ: Long-press any bib to set status. After Finish Race, any started runner without a finish is automatically classified DNF. - Handicap-aware live results: Each row shows start-from-gun, finish-from-gun and personal time on a single compact line, plus an S1/S2/... rank for the order runners crossed the start line. Group results by gender or age group. - By Line / By Time toggle (handicap): Switch between order-crossed-the-line and fastest-personal-time at the tap of a button. - Name autocomplete: When adding a competitor, start typing and Timing Mate suggests names from your previous events, populating gender and age group in one tap. - Lockable results: Finish the race to lock the data and prevent accidental edits. Reopen if you really need to. - Export & share: One-tap CSV and TXT export to text, email or social media. Handicap CSVs include StartFromGun and FinishFromGun columns. - Completely offline: No mobile data or Wi-Fi required. Perfect for forest, fell, and rural club venues with no service. - Private by design: All competitor data, splits and results stay on your device. No accounts. No cloud. No telemetry. Timing Mate is built for volunteers by a volunteer, with every feature shaped by real club races. If you can hold a phone, you can run timing.

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.

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.
