Generating… usually about a minute.
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.

TorqueTrailPulse — Driving Telemetry TorqueTrailPulse turns your iPhone into a lightweight driving telemetry companion. Capture live driving stats, understand how your car responds, and review your runs — all in a clean, distraction-free interface designed for use before and after a drive. Whether you’re curious about acceleration, braking, or road smoothness, TorqueTrailPulse gives you simple, visual insights using your device’s sensors. Allow background recording so your drive continues tracking even when your phone sleeps. Now supports: - CarPlay support - Apple Watch app - Live Activities - Siri automation - AI-generated insights - Video highlight generation - Encrypted backups - Driver persona based off past drive data - iCloud sync Key Features Live Telemetry • Real-time speed • Acceleration (longitudinal G) • Cornering force (lateral G) • Road smoothness score Performance Metrics • 0–100 acceleration timing • Braking distance estimates • Run duration and distance Drive History • Automatically saves completed runs • Review past sessions with clear summaries • Compare smoothness and performance over time Lock Screen & Live Activity • Optional live status on Lock Screen and Dynamic Island • Glanceable speed and recording state Privacy-First • Runs are stored locally by default • No account required to start using TorqueTrailPulse • Location and motion access are used only to compute driving metrics Battery-Aware • Background recording is optional • Adaptive sensor sampling to reduce battery usage • You control when recording is active Private iCloud Backup Create a private iCloud restore point for your run library. Encrypted Export Create a passphrase-protected backup file you can save and import later. If enabled, private iCloud backup stores your backup in your personal iCloud account for restore. The app developer does not access this private iCloud backup data. Designed for Drivers TorqueTrailPulse is built for: • Car enthusiasts • Track-day practice (non-competitive use) • Smoothness monitoring on long drives • Curious drivers who want deeper insight into their driving patterns The interface is optimized for clarity and safety. Interactions are kept minimal while driving, and detailed analysis is available when stopped. Important Notes • Telemetry accuracy depends on device sensors and mounting position. • Road conditions, vehicle suspension, and phone placement affect readings. • Continuous GPS and motion tracking may increase battery consumption. • TorqueTrailPulse is not a navigation app and does not replace your vehicle’s instrumentation. Permissions Explained TorqueTrailPulse requests access to: • Location — to calculate speed and distance • Motion & Fitness — to estimate acceleration, braking, and smoothness • Notifications (optional) — to show run status These are used only to provide core app functionality.

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.
