Evidence scope: No current overall US chart position is available. Category-chart positions shown in discovery are a separate scope. Revenue is a directional model estimate, not verified earnings.
A product spec, screen plans, and build steps for your coding agent.

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.

Never misread a putt again. PuttView shows you exactly why you're missing. The average amateur golfer takes 40 putts per round, while PGA Tour players only take 29. This 11-stroke gap is the most recoverable gap in golf - and PuttView helps you close that efficiently. Instead of just rolling putts, start practice deliberately with immediate and accurate feedback on every putt. Using your iPhone's LiDAR sensor, PuttView scans any green and overlays precise, data-based visuals directly on the surface. Contour lines, slope arrows, the correct putting line, aiming point, and speed and distance data. All in real time. On any real green, indoors or outdoors. No guesswork. No estimation. Just the read. What PuttView shows you: Contour Lines See the exact topography of the green. Scan any surface, with or without a putt lined up. Understand how it breaks before you ever address the ball. Slope Arrows: Instant directional cues showing the fall line at every point on the green. The exact direction the ball would roll downhill. Read the green faster, more accurately. Ideal Line: Not just the optimal line. The correct line, calculated for perfect pace. See exactly where your ball needs to travel from the moment it leaves the putter face until it hits the bottom of the cup. Aiming Line & Aiming Point: A precisely defined start direction and target point. Eliminate alignment guesswork entirely. Putt Info: Speed, distance, and break data for every putt. Build a feel for pace and line grounded in real numbers. Built for golfers who take their game seriously. The PuttView app is not a simulator. It works on any green, outdoors, and indoors. The same technology trusted by tour professionals, elite coaches, and leading training facilities worldwide is now in your pocket. Scan. Read. Putt.

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.
