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.

YOUR KART. YOUR TEAM. YOUR RACE-DAY HISTORY. Keep the details behind every lap together. KartTrackerAI is a trackside logbook for owner-drivers, parents, mechanics, coaches and race teams—not just a live results screen. GARAGE, SETUP, TIRES & SESSIONS Manage multiple karts with photos, chassis and engine details. Record chassis settings, gearing, fuel, tire sets and usage, and cold/hot pressures. Plan sessions and keep track configuration, conditions, driver, class, notes and photos alongside lap times, laps, positions and recorded engine data. Compare what you changed with what happened on track. LIVE TIMING & TEAM COMMUNICATIONS Follow supported events, classifications and lap times; filter classes, highlight drivers and review supported completed-result imports. Share text, photos and PDFs in a persistent Team feed, with team-wide or class-based alerts. All members can see posts; class targeting controls alerts, not visibility. Live Timing and team communications require a Team subscription. Feed coverage varies by provider; alerts depend on connectivity and notification settings. DRIVER PROFILES Add driver photos, associate karts and assign shared-kart sessions to the right person. Review completed-session history, starts, wins, podiums and personal bests by track and class. Statistics reflect your recorded history. Designed for iPhone and iPad with clearer navigation, team synchronization, email-link sign-in and membership-based access. Core app: iOS/iPadOS 18+. Advanced Siri actions require iOS 27. Supported photo workflows can use OpenAI, Claude or eligible Apple processing, including Private Cloud Compute on iOS 27. AI photo processing requires an active AI Image Processing subscription. Apple features depend on device eligibility, OS version, language, region, model readiness, connectivity, service availability, and usage limits. AI results may be incomplete or incorrect; review extracted details before saving. Photo analysis can be turned off in Preferences. TURN RECORDED LAPS INTO A CLEARER NEXT MOVE On compatible Apple Intelligence devices, the Analysis workspace brings together personal bests, recorded setup changes, gearing and tire-pressure baselines, lap consistency, and track conditions. Build a shareable Event Report from completed sessions at one track, including results, setup, weather, photos, and suggested next experiments. Analysis and report generation depend on model and language availability. KEEP THE WORK BETWEEN SESSIONS Record maintenance for each kart: work performed, parts, notes, costs, engine hours, and lap count. Optional AI processing also supports photo and voice entry and official results-sheet import. Optional team synchronization helps drivers, parents, mechanics, and coaches work from the same kart history. WORK IN YOUR TEAM'S LANGUAGE Use the interface, Analysis, and Event Reports in English (US and UK), Spanish (Mexico and Spain), Polish, German, French, Brazilian Portuguese, Traditional Chinese, Dutch, and Japanese. Supported image workflows let you choose source and output languages separately. Session notes remain as entered. The paid download includes local kart, setup, session, tire, photo, results, and maintenance tracking. Some optional processing and team synchronization features require a subscription. Availability varies by feature. Subscriptions automatically renew unless canceled at least 24 hours before the end of the current period. You can manage and cancel subscriptions in your App Store account settings. KartTrackerAI supports trackside judgment. It does not replace the driver or mechanic, and recorded associations do not prove that a setup or maintenance change caused a performance result.

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.
