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

Let's Save your money, and your data. We help you save more by encouraging mindful spending through active participation and easy tracking of your spending. * ULTRA SIMPLE: No account sign-ups, bank connections, or company servers. Your data is saved on your device using Apple's Core Data. * INTENTIONAL AND EASY: Instead, of being a passive viewer, intentionally add your discretionary spend in a few taps, reinforcing good spending habits. * STRESS FREE: Set an easy to change monthly spending target instead of figuring out and limiting yourself with a strict budget. * SELF ACCOUNTABILITY: Use handy widgets to track your spending and progress, as you get closer to financial freedom. --- # BEING INTENTIONAL HELPS YOU GROW Let’s Save approaches budgeting differently. By making you an active participant in your spend tracking, you leverage reinforcement behavior learning to change how you act–rather than being a passive viewer only looking negatively at charts representing past spending behavior. Every time you spend something, simply type in what you spent and press a category to add and group it, all at once. # DONE IS BETTER THAN PERFECT Our app is designed to help you improve yourself, not just keep track of your finances like a bank would. Focus on isolating your discretionary spending, the expenses that you can actually change, rather than tracking every single bill or expense. You probably already know that you need to pay for essential bills like your water bill, so instead, let's focus on the small, everyday expenses that add up over time. After all, it’s better to isolate your discretionary spends: the ones you can actually change. # NO STRESS SPENDING Let's Save believes in stress-free spending. Traditional budgeting can be overwhelming and stressful, but with Let's Save, you don't have to worry about setting the perfect budget. Instead of strict budgeting, Let's Save helps you set a monthly target that you can adjust as needed. This target is simply a tool to remind you where you are in terms of your spending and savings goals. You deserve to enjoy your hard-earned money without the stress of strict budgeting. # KEEP UP THE GOOD WORK Rather than thinking of your budget as a strict goal, we encourage you to see it as a tool to track your progress towards your financial goals. Our handy widgets make it easy to see how close you are to your monthly spending target. Even if you don't hit your target every month, tracking your spending can help you understand better your spending habits. For example, knowing you’re 200% over $100 target, means you’ve spent $200. With that in mind, you can continue to focus on being mindful about your expenditure. # Flexible and Simple Whether you're on the go or taking a moment to reflect on your spending later, our app makes it easy to track your expenses. On location and waiting for the receipt? tap the widget, add, and save. Automatically add your location to help you remember where you spent. Or maybe, you’ll remember later and add it then. You can add a note to remind yourself what the expense was for. Make a mistake, simply swipe it away.

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.
