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.

Hypothesis 2

Create a guided onboarding experience.

Assumption to check: User interface can be confusing for new users

Validate with people who use this workflow before building.

Hypothesis 3

Add customizable alerts and notifications.

Assumption to check: Lack of customizable alerts for severe weather

Validate with people who use this workflow before building.

Hypothesis 4

Optimize app performance for low-end devices.

Assumption to check: Performance issues on older devices

Validate with people who use this workflow before building.

App Store description

Know before you go. AI-powered marine weather and fishing reports. Plus GPS tracking and ocean maps — SST, CHL, bathymetry, thermocline, currents, eddies, thermal fronts. SeaLegs AI is built for boaters, sailors, cruisers, and anglers who want a sharper forecast than a generic weather app and a clearer plan than a stack of satellite tabs. One app, four tools. — WHO IT'S FOR — Day-trippers, sandbar regulars, and weekend cruisers picking beach days, harbor hops, ICW legs, and marina-to-marina runs with family aboard. Sailors on coastal passages, overnight hops, gunkholing, and bluewater crossings — reading wind, swell, and the windows between systems. Offshore anglers trolling, jigging, chunking, bottom fishing, kite fishing, and daytime swordfishing the canyons, ledges, and thermal breaks. Power boats, sailboats, catamarans, sport fishers, yachts, and trawlers. — MARINE WEATHER — AI-powered marine forecasts for your route and departure — a beach day, a coastal passage, or a run offshore. We aggregate ECMWF, GFS, and ICON — three of the top global weather models — then translate thousands of wind, wave, swell, and gust data points into one plain-English read. — FISHING REPORTS — AI fishing forecasts for a chosen area and date. Reads sea surface temperature, chlorophyll, currents, and bathymetry — the same data offshore pros pay subscriptions to interpret — then highlights the top spots with a plain-English write-up on why they're fishing now. Fishing Reports are available in the U.S., Canada, Mexico, the Caribbean, Central America, the northern coast of South America, and the Arabian Sea. Coverage expanding. — GPS TRACKER — Real-time tracking with condition alerts, inshore or offshore — a beach run, a coastal hop, a troll offshore. SeaLegs watches for weather changes that could affect your run home. Push notifications when a shift matters — silent when it doesn't. — OCEAN MAPS — Live ocean-data map layers: sea surface temperature (SST), chlorophyll (CHL), bathymetry, thermocline, ocean currents, eddies, and thermal fronts. Read the water the way a captain does — temperature breaks, color edges, depth contours, the layer fish hold under, the current seams that carry bait, eddies that pile bait against themselves, and the sharp thermal fronts that concentrate life along their edges. Ocean Maps cover the same regions as Fishing Reports — coverage expanding. — HOW IT WORKS — 1. Plan. Drop a pin on your destination, pick a departure time, and tell us about your boat. 2. Analyze. The AI reads weather and ocean data for your specific route and area — not a regional average. 3. Decide. Get a simple Go / Caution / Avoid recommendation, with hourly detail and alternate timing if today is marginal. — WHY SEALEGS AI — No subscription traps. Marine weather, GPS tracking, and ocean maps are free to use where available. Fishing Reports are pay-per-report — pay when you need one, skip when you don't. Built by boaters. Tested offshore. Updated every release with the features captains ask for. Get your SeaLegs before you go. NOTE: SeaLegs AI is for marine weather forecasting over the open ocean. It is not to be used for navigational purposes. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

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.
