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

FlagStat is a flag-football tracking app for recreational leagues. It replaces pen-and-paper scorekeeping with a simple, ref-driven game tracker that everyone in the league can follow. This is the V1.1 pilot build — you're testing an early version with our league. Focus your feedback on what felt natural and what felt clunky during a live game. What you can do • Run a live game. Refs use a single iPhone or iPad to track plays, scores, the play clock, and timeouts in real time. • Manage your league. Create a league, invite members with an 8-character access code, set up rosters and schedules. Commissioners can assign players to teams from the team page; players can also pick their own team after joining. • Three roles. Players follow their team's stats; Coaches manage one team's roster; Referees run live games. The role you pick at sign-up determines what you can do across the leagues you join. • House rules + Ask the Ref. Commissioners write league-specific rules (mercy rule, equipment, timing, sportsmanship, custom). Refs see them alongside the standard rulebook during a game, so close calls don't slow things down. • Offline-first for refs. Keep tracking even when wifi at the field is spotty; everything syncs when you're back online. • See the season. Schedule, standings, top passers/receivers/rushers/defense, and recent box scores all live in the League tab. What's coming after the pilot • Sideline video review and per-game video review (cut from V1 to keep this build focused). • Highlight reels and per-player video exports. • League brackets and playoff scheduling. • Live spectator mode (players across the league can follow the ongoing games in real time without the ref's device). Sign in with Apple — we never see your password. Privacy policy: https://flagstat.app/privacy Questions: [email protected]

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.
