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

GENERAL The Pitch Locator PRO was designed by a Pitching Coach and developed on the premise of tracking pertinent pitch data with your device. All data is stored in your device with the option of exporting to players-coaches-scouts. Pitch Locator Pro is the premier app for tracking pitcher statistics. No more pencil/paper. Our new app stores and calculates the most relevant metrics when your Pitcher is on the mound or in the circle or when scouting opponents. Scouting has never been smarter! Whether tracking pitches or at-bats, the PL PRO does both. PITCH MENUS -Baseball: Fastball -2 Seam -4 Seam Curveball Change-Up Slider Split Finger Knuckleball Other -Softball: Fastball Runner Offspeed Screw Change Backdoor Curve Drop Curve Drop Rise Other PITCHING COACHES Bullpen sessions have never had better digital tracking and instant feedback of where pitchers are throwing and if they are hitting their spots. Quality Pitches are tracked throughout the session and when finished, your pitcher’s Quality Pitch Percentage is calculated giving you and your pitchers instant feedback to the success rate of the session. With our Play Back feature, you can replay EVERY pitch of a bullpen session. www.gamegrade.com IN-GAME All At-Bats, Current Hitter and The Next Batter. Now, when calling pitches, you have the data on who’s at the plate as well as who is up next. Set-up pitches are a must and our app allows you to look ahead and call the perfect pitch at the perfect time. Our Pitch Sequence feature allows you to see the order of pitches thrown as well as what the hitter did with each pitch. Red Letters- Strike Blue Letters- Ball Swing/Miss {Underline} Foul {Strikethrough} INSTANT STATS IP/TP/B/S/R/FPS/K/H/BB/HBP/WHIP/DICE/OPP.OBA/OPP.Slugging/ER/ERA/Strike % Screenshots at www.gamegrade.com HOT ZONES The PL PRO will track pitches inside our 9 section Strike Grid. Our At A Glance feature allows you to see the number of pitches in each section as well as shades of red or blue in each section differentiating specific hot zones. If a pitcher throws 9 pitches in the middle left section, that particular section will ‘heat up’ and show red while the lower left section with 2 pitches will show a blue color. Also, the hotter the zone, the darker the number in that section. PITCH SUCCESS Pitch success is tracked as pitch type within the grid. The more Change-Ups thrown for strikes, whether hit or called the more successful the pitch. POST GAME -PL Exports Automatically build your scouting reports. Data exports as a working .csv file that opens in Excel, allowing you to present the data in raw form directly to your player/coaches/scouts or customize your reports for coaches/players/scouts. All pitching data is included in the file as well as each at bat. -Spray Each export will include a spray chart showing where balls were hit to throughout the game, as well as the outcome of each at-bat. Along with the spray and stats, every at-bat, pitch count of every at-bat, as well as outcome of each at-bat is catalogued in the app and listed in the export.

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.
