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

Boat Beacon is an internet AIS receiver and transmitter for your iPhone and iPad. It is the only AIS ship tracking app to provide Collision Warnings, share your boat’s position & use real-time AIS data. Connected to the largest network of AIS shore receivers world-wide covering most major ports, harbours and popular coastal areas. “An outstanding app, with great potential. Both interesting to use and very user friendly. This could be a life saver and especially of interest to small boat users. Everyone who goes on the water should have this on and use it!” ***** Sun Dream, App Store Review Boat Beacon is designed for boaters & provides continuous Bearing, Range & Closest Point of Approach (CPA) calculations and alarms in addition to standard AIS information even when in the background. Boat Beacon does not require any external AIS transponder or receiver equipment. Key Features ------------ Over-the-horizon collision avoidance (30 miles radius) using continuous CPA calculations - highlights boats that are on a potential collision course and alerts you with an alarm. Continually transmits and receives position information via the internet and calculates and alarms CPA even when the app is in the background. Shares your position with Internet AIS Systems & apps & other Boat Beacon users in real time. Real time ship map view with North up & Heading up modes so you can look in the direction of the ships on the map to locate them. Nav display showing own boat's speed, course, heading and position. SART Alarm Man Overboard tracking, Anchor watch & Theft alarms (IAP). Apple Watch App included Siri voice commands Export tracks Boat-to-Boat & Group Messaging. Local AIS & GPS via Wifi. Boat Beacon InApp Add-ons:- LiveView - Augmented Reality view with ships, compass & horizon overlaid. Works with FLIROne IR cameras as well to see ships & people in the dark & fog (IAP) "AIS Sharing" to other apps like Navionics & iNavX (IAP subscription) US, UK and IE Marine raster charts (IAP). MOB and Anchor Watch (IAP). Let Friends and Family see where you are and where you're headed to with our free Boat Watch app or on web-based AIS systems like MarineTraffic which have free web viewers available. Arm all the crews in a race with Boat Beacon and have real time updates on the race positions on the water and back in the club house. Keep a watch and in touch with other boats in your flotilla when sailing in a group. Boat Beacon requires internet access to work. Most popular coastal areas have cellular data access extending 12 or more miles out to sea. Subscriptions The "AIS Sharing " subscription is monthly ($5.99) or yearly ($16.49), and will automatically renew at the end of the subscription period unless auto-renew is turned off at least 24-hours before the end of the current period. Payment will be charged to your iTunes Account at confirmation of purchase, and will be charged for renewal within 24-hours prior to the end of the current period. Subscriptions may be managed by the iTunes account holder and auto-renewal may be turned off by going to Account Settings after purchase. 
No cancellation of the current subscription is allowed during active subscription period. Terms of Use: http://seanav.net/termsofuse.php Privacy Policy: http://seanav.net/privacy.php Support: [email protected] Your position can be shared and seen on all our apps without using an MMSI number. To be seen on Global AIS systems like MarineTraffic you need an MMSI number. In the US you can obtain one by visiting http://www.boatus.com/mmsi or email us for a free internet MMSI number. Please note that continued use of GPS running in the background can dramatically decrease battery life. NOT FOR NAVIGATION Boat Beacon should only be used for basic navigation reference and should not be solely relied upon to determine precise locations, proximity, distance, or direction. You will not be visible to other ships on VHF only AIS systems.

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.
