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.

KinetIQ Putting Trainer turns your iPhone and Apple Watch into a portable putting lab—no launch monitor required. Using the Apple Watch on your lead wrist and your iPhone in front of you, KinetIQ Putting Trainer shows you what your putter face is really doing through the stroke. The iPhone provides clear visual feedback, while the Apple Watch adds haptic cues so your hands and brain learn together. Face Control – Train a Square Clubface Most golfers think their putter face is square. KinetIQ lets you measure it. • Calibrate by setting up with the putter face square to your intended start line, then tap Calibrate on the iPhone. That position becomes your personal 0°. • During your stroke, the app displays live face angle in degrees (positive = closed, negative = open). • A vertical color-coded “heat bar” makes face control easy to read at a glance: • Green when you’re close to square • Yellow when you’re slightly open or closed • Red when the face is significantly open or closed and likely to miss your line • When the face rotates beyond your threshold, a gentle tap on the Apple Watch lets you feel that you’ve lost control—even if you aren’t looking at the screen. This combination of number, color, and feel helps you learn how much face rotation is normal for your stroke and how to get the face back to square at impact. Metronome – Groove Tempo and Distance Control Speed control starts with consistent tempo. The built-in Putting Metronome helps you find and repeat your best rhythm: • Adjust beats per minute (BPM) on the iPhone until the cadence matches your best rolls. • The iPhone provides a clean audio click, while the Apple Watch mirrors the beat with subtle taps. • Use the beat to time the start of your backswing and impact so your stroke length and timing become repeatable. Use the metronome on its own to train rhythm, or combine it with Face Control to work on tempo and clubface behavior at the same time. Built for Real Practice, Anywhere KinetIQ Putting Trainer is designed for everyday golfers, competitive players, and coaches: • Practice on the putting green, at home, or in the office with a putting mat. • Use it for warm-up to quickly calibrate your setup, check face rotation, and lock in your tempo before a round. • Ideal for both blocked practice (same distance) and random practice (changing distances and breaks). Because it runs on your iPhone and Apple Watch, you get objective, tour-style feedback without buying extra hardware. Key Features • iPhone + Apple Watch pairing for synchronized visual and haptic feedback • Face Control mode with live face angle in degrees • Color-coded vertical heat bar to show how open or closed the face is • One-tap calibration to your personal square setup • Haptic alerts on the Apple Watch when the face rotates beyond your chosen window • Adjustable putting metronome with sound on iPhone and taps on Apple Watch • Simple, clean interface designed specifically for putting practice KinetIQ Putting Trainer helps you measure what your hands and clubface are doing—then train them to do it on purpose. Instead of guessing if your putter is square or your tempo is “about right,” you get clear, immediate feedback on every stroke.

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.
