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.

Anything you want to do a certain number of each day, week, or month can be tracked with Point Tracker. Set up your regular allowance, and add (or subtract) your amount with one button press. Then add or subtract each time you make progress toward your goal. For instance, I use it to count calories. I give myself 1750 calories a day, and then subtract how many I've eaten. Each workout I add in what I've earned. Each morning I give myself my day's allowance. This way I always know how many calories I have left each day. Can I have a piece of cake? It's a piece of cake to tell! If I need to reduce my daily calories, I can just lower my allowance. Not sure if you gave yourself credit for that workout this morning? Check the history! You can do the same thing for miles you want to run each month, or dollars you want to spend on lunch each week, or compliments to pay your significant other. Budget money you want to give to homeless people. Track your points in Cribbage. Or Quidditch. Set the golf score you want to beat, and subtract one for each swing of the club. Anything you want to track, Point Tracker makes it easy! Icon made by https://www.flaticon.com/authors/vectors-market from www.flaticon.com

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.
