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.

A tool designed for youth baseball coaches, to save you tons of time and keep you organized and informed. Also works great for softball, kickball, etc. or just tracking your personal stats. Syncs with iCloud to all your devices, and you can share with others, too. I've been coaching little league baseball for over 6 years. I've tried paper scorebooks, spreadsheets, and smartphone apps but nothing worked quite the way I wanted. I created something that will save you HOURS of time, year after year - isn't that worth a few dollars to you? The season starts with practices. Pocket Coach provides an attendance keeper for practices. I don't know about you, but I reward players who show up for practices. Simply check off who is present, and now you have that information for later when you are planning your lineup. In baseball, rain happens. You probably need to send out a quick notice to parents and players when an event gets canceled or delayed, when you're at the field away from your computer. You can store 2 emails and 2 mobile phone numbers for each player, and in seconds blast out a team email or text message. Parents appreciate that! Planning the lineup for games is what I used to spend alot of time on. In little league, players will often play different positions throughout a game. A good coach will think this through carefully ahead of time, and lay out each position for each inning, including bench time. (Of course, changes may occur based on game situations, and being able to quickly change this on the fly is a great feature of this app.) How often did your lineup accidentally include two left fielders and no center fielder? Doh! Pocket Coach will clearly highlight positions in red when you mess up. I also like to consider how often each player has played in the infield, in the outfield, sat on the bench, etc. when planning the lineup. You have all of this information at your fingertips now! When you're done, you can print a lineup sheet directly from your phone or email it to another coach. For younger leagues, you may just want to randomize the fielding positions, and you can do that too. I've long ago given up trying to decypher scorebooks when tracking batting averages etc., so I would always write my own notes on an index card, and plug that into a spreadsheet later. As a coach, you care about batting RESULTS. With a couple screen taps, you can quickly and easily record a batting result: single, strikeout, fielders choice, whatever. Very simple, anyone can do it with no training. Later, you can pull up all the important batting statistics. It's very important to keep track of how many pitches each pitcher has thrown, and there is a pitch counter built in. It also tracks balls and strikes, walks and strikeouts, hits and outs, and runs. Of course, a baseball coach usually coaches multiple teams over the years, and Baseball Pocket Coach supports as many teams as you want. You might play softball yourself and want to track your own batting stats but not the entire team, you can do that! Some parents might want to use Pocket Baseball Coach to track their own child's stats, and use the group email and texting features. Trust me, it's way easier to use than the "free" apps out there! (Nothing is free if it gives you a headache to try to use it : ) With Pocket Coach you can print or email a ton of reports directly from your iPhone, iPad, or M1 Mac. Geek out all the way and use an iPad in the dugout for your players to see, while you make changes on your iPhone. Runs great on a Mac with Apple Silicon.

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.
