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.

Money Flow is finally here, and it’s ready to help you keep track of your expenses and achieve your personal savings goals. The app is super simple to use, and leaves out special algorithms and computational guess work in order to put you in control of expense tracking. Because of this, there is no external account linking required and you can rest assured your data is never being analyzed, sold, or stored anywhere other than on your device. Simply set your monthly income, fixed expenses, desired savings goal and start budgeting. SEE THE BIG PICTURE When you launch the app, you are presented with your Dashboard. Here you can see how you’re doing with your current budget. Helpful insights about how much money you’ve spent, or how many days are left in the month are readily available to you. Additionally, you can keep tabs on your three most recent expenses at all times. ADD EXPENSES Simply tap the add expense button located on the bottom right corner of your Dashboard and enter a short note, a dollar amount, the date and category of your expense. That’s it. Made a typo? Navigate to the All Expenses screen and tap on the expense you need to change. GET A BREAKDOWN OF YOUR SPENDING When you navigate to the All Expenses screen, you can also select the Category Breakdown segment to get a more detailed look into how you’ve spent on any given category. Tap one of the pie chart slices to switch categories, or use the convenient back/forward buttons to cycle through them all. Want to see on which days you had certain expenses? Pull up the expenses drawer from the bottom and scroll through all expenses for that category. CUSTOMIZABLE BUDGET Did you get a pay increase? Have a new fixed monthly expense? Do you want to save more? Save less? You can edit any one of your budgeting preferences by simply going to the Settings screen from your Dashboard at any time. TRAVEL THROUGH TIME Our relationship with our finances changes over time. Understanding the entirety of your financial picture can be very helpful for you to realize your personal goals. You can navigate to past months straight from the dashboard, by tapping the back/forward buttons. If you want to see a completely different year, just select a new one by tapping the year button right above your month display. COMPACT OVERVIEWS When viewing a previous budget month, you will be able to see your overview for that month. You’ll see your budget preferences for that month, whether you were over or under your budget, as well as your highest and lowest category spend. And just like in your current budget month, you can get access to all your individual expenses and your breakdown as well. WIDGETS Money Flow has three widgets for you to display on your home or lock screen. There’s the Insight Widget that shows you one of your key insights, such as your savings potential. There’s also the Category Widget for helping you keep track of your spending on an individual category. Finally, there’s the Insight Overview widget, which shows you all your insights without even having to open the app. PRIVACY We believe your data should be yours. That’s why Money Flow will never require you to link your financial accounts or mine any of the data you submit. What are you waiting for? Improve your savings game and track your expenses with Money Flow today.

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.
