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

Join 3.5 million customers using Flex. Split your rent into 2 payments—the first when it's due, the second on a date you choose during the month. When unexpected expenses hit, Flex gives you breathing room, whether you're paid weekly, biweekly, or have variable income. Your landlord or property gets paid upfront. Help build your credit history with on-time payments. Still have money left over on the 1st. HOW IT WORKS 1. Apply for Flex. If approved, set up your address and choose your payment schedule. 2. Your rent gets paid in full to your landlord or property. 3. You split rent payments in 2: half when rent is due, half before the end of the month. BUILD CREDIT FOR PAYING RENT Your on-time payments are reported to all major credit bureaus at no extra cost, so the rent you already pay can help to build credit history. SEE, SPLIT AND PAY YOUR BILLS IN ONE APP Flex is the app to split and pay your bills. Split your rent, car payment and everyday bills into smaller payments on dates that work for you. TRANSPARENT PRICING, BUILT TO GET YOU AHEAD What it costs: up to $5.99/month for the Flex membership, a 0.5% processing fee on the total bill amount, and a split fee of up to 3% of what you borrow (no reduction with early repayment). Debit card: no added charge. Credit card: 2.5% surcharge. FAQs - Can I pay rent, or my bills, in installments? Yes. One payment when your rent is due, a second later in the month, on a schedule you choose. - Is Flex a loan? No. Flex provides a line of credit through its bank partners, not a loan. - Does Flex report to credit bureaus? When turned on, on-time payments are reported to TransUnion, Experian, and Equifax, which helps build your credit history, included free with your Flex membership. *The #1 rent splitting app based on app store reviews, 2026.
