Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.

Feature spec

Goal: Send a clear invoice after finishing a job.

  • Add a client, line items, a due date, and payment instructions.
  • Preview the total before exporting a PDF.
  • Keep an editable draft if export fails.

Screen plan

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.

Differentiate and validate

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.

App Store description

Transform your training sessions with this cutting-edge iPhone / iPad Long Jump Video Analysis App — the ultimate tool for athletes, coaches, and enthusiasts aiming to elevate their performance! This powerful app analyzes videos you've previously recorded, providing precise bio mechanical insights and detailed measurements to optimize every aspect of your jump. User can calibrate with confidence using our comprehensive multi-point calibration system, accounting for camera perspective, athlete height, and board-to-pit distance, delivering unmatched accuracy. Visualize your jump with full frame-by-frame playback controls and detailed analysis reports that include hip rise, height gain, angles, velocity, power metrics, and technique assessments. Whether you're refining approach runs, takeoff angles, or landing techniques, our preset configurations cater to all skill levels, from beginners to elite athletes. User calibration of each jump using our unique multi-point Calibration System will provide the best analysis: • Athlete Height → vertical measurements • Athlete Gender → performance benchmarks • Board Distance from Camera → primary calibration • Takeoff Board → position validation • Takeoff Point → accurate takeoff position tracking • Pit Edge → official distance measurement, landing analysis • Landing Zone → for improved technical analysis • Board-to-Pit Distance → secondary calibration reference • Camera Height → perspective correction • Camera Angle → 3D trajectory correction How it works: • Tap to place markers on video thumbnail • Tap twice for Takeoff Board’s draggable Vertical Line Markers • Drag to adjust - markers are fully draggable • Visual feedback with icons and labels • Checkmarks show which markers are set • Perspective correction: Accounts for camera angle and height • Dual-reference calibration: Uses both camera distance AND board-to-pit distance, averages them for maximum accuracy • Help system: Built-in tutorial explaining how to calibrate Full Video Playback with Frame-by-Frame Controls: • Frame backward button • Stop button (returns to start) • Play/Pause toggle • Frame forward button • Speed control menu (0.25x, 0.5x, 1x) • Time Slider - Shows current time and allows scrubbing through the video with precise timestamp display Emailed analysis can include: MEASUREMENT DATA - Hip Rise at Board - Total Height Gain - Max Approach Angle - Max Takeoff Angle - Max Distance Before Board - Max Distance After Board PENULTIMATE STEP - Step Duration - Penultimate/Takeoff Ratio - Plant Foot Distance - Plant Score JOINT ANGLES AT TAKEOFF - Hip Extension - Knee Angle - Ankle Angle - Knee Drive Height - Hip Extension Angle VELOCITY ANALYSIS - Horizontal Velocity - Vertical Velocity - Velocity Ratio - Speed Conversion to Vertical POWER & PHYSICS - Takeoff Power - Takeoff Force - Takeoff Efficiency - Kinetic Energy - Momentum - Hang Time - Efficiency FLIGHT ANALYSIS - Flight Distance - Flight Path Quality - Flight Efficiency - Time to Peak - Flight Duration - Horizontal Distance TECHNIQUE - Ground Contact - Knee Drive - Arm Drive - Landing Technique - Landing Efficiency SCORES - Overall - Performance Grade - Approach - Plant - Takeoff - Flight - Landing ALSO>>> RECOMMENDED DRILLS & TRAINING RECOMMENDATIONSALSO>>> RECOMMENDED DRILLS & TRAINING RECOMMENDATIONS

Build scope

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.

Define the first version

Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.

Set boundaries

Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.

Check the hard parts

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.
