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.

TidesPro is a fast, powerful, and easy-to-use app for tides and marine weather. Get accurate tide predictions and marine weather throughout NOAA-covered waters — whether you’re fishing, hitting the beach, boating, kayaking, surfing, or planning a trip. Beyond tides, get detailed marine conditions, NOAA marine forecasts, and buoy observations to plan for the future or react to changing conditions. For anglers, TidesPro offers fishing time recommendations and daily fishing ratings. Tap ⋯ on the top right on several screens to access settings to show even more fishing info. TidesPro also puts tides, marine weather, and fishing times on your wrist with a super fast Apple Watch app — plus widgets and complications for your Home Screen, Lock Screen, and watch face for quick access without ever opening the app. In addition to all that, it’s super privacy conscious with no tracking, and available on all your Apple devices: iPhone, iPad, Apple Watch, and Mac. TOP FEATURES • NOAA Tide Data: Tide heights & tide times including interactive tide charts, weekly & monthly tide tables, high tide times, low tide times, and a ton of visualization options • Marine Weather: Wind, waves, swell, water temperature, and conditions for most locations • Interactive Map: Explore tides, wind, waves, and water temperature with overlays for wind, radar, nautical charts, satellite imagery, underwater topography, and more • Fishing Insights: Best times to fish, including solunar periods and a daily fishing rating (extras in ⋯ menu on several screens) • Widgets: See tides, solunar predictions, waves, and wind at a glance for nearby or favorite stations — right on your Home or Lock Screen. (Premium) • Apple Watch: See tides on your wrist in the app or on the watch face with complications, along with wind, waves, swell and conditions (Premium required for complications) MORE FEATURES • Local Tides: Grant location access, and quickly access current tides near you with the current height alongside quick tide charts, tide tables, a tide clock, sun & moon times, moon phases, and fishing times • Favorite Stations: Conveniently track tides at locations you care about most • Marine Weather Forecasts: Including wind, waves, swell, and conditions for most locations • Sun & Moon: View sunrise, sunset, moon phases, major & minor solunars, nautical & civil dawn & dusk • NOAA Marine Zone Forecasts for most locations (Premium) • NOAA NDBC Buoy Observations for many locations (Observation types vary, and not all locations are near a buoy) • Tide Marks: Track a reference level, such as a tide height where your boat or kayak can clear certain area • Tide Alerts: Set a tide alert to receive timely high tide & low tide notifications for your chosen location (Premium) • Live Activities: Track tides, sun, or moon events on your Lock Screen or Dynamic Island (Premium) PRIVACY-FIRST TidesPro respects your privacy: an identifier ONLY when you use Live Activities because it's required to push updates, and it's never used to track you. Feel free to check out TidesPro using the App Privacy Report on your device and compare against other apps. PREMIUM The free version shows ads for the Premium service and has some features locked. Premium has a 1 week free trial, so you can try it out. NOTES • Provides NOAA tide and current predictions in NOAA-covered waters which include the United States and much of the Caribbean, including California, Florida, Texas and all major coasts (East, West & Gulf), plus Hawaii & Alaska • Requires an internet connection. Tide data is cached from the internet for your favorite and recently viewed stations, so it’s available offline when you've accessed those stations recently. Weather data always requires an internet connection. • TidesPro uses its own API backed by NOAA data for tides predictions Terms: https://www.tidespro.com/about/termsofuse Privacy: https://www.tidespro.com/about/privacypolicy

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.
