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

Stop overpaying. Start shopping with confidence. Whisprice is a universal price tracker that works across the entire web. Not just one marketplace. Not just a handful of stores. Any product, any retailer, anywhere online. Paste a link. Set your target. Let Whisprice do the watching. - Track Any Product, From Any Store Most price trackers lock you into one platform. Whisprice doesn't. Whether you're eyeing a laptop on a tech retailer, a sofa from a furniture brand, or a limited-edition item from a boutique shop, if it has a URL and a price, you can track it. - Get Notified at Exactly the Right Moment You don't need to check prices manually. Whisprice monitors your tracked products and sends you an alert the moment the price changes. Set your target price and we'll notify you when it's hit. No noise, no spam. Just the signal you actually need. - Know If a Sale Is Really a Sale Price history is built into every product you track. See how the price has moved since you started watching it, so you can tell at a glance whether a "limited time offer" is genuinely worth acting on. Real data. Real clarity. - Your Wishlist, Your Way Whisprice is more than a tracker. It's a personal shopping hub. Add products to your wishlist, write notes, set target prices, and score each item based on what matters to you: quality, value, desire, priority, and more. Everything you're considering, organized in one clean place. - Stay on Top of Stock Price isn't the only thing that matters. Whisprice also monitors stock availability so you're not caught off guard when a product sells out. Track both the price and the status, side by side. - Understand Your Shopping Decisions Once you've made a purchase, Whisprice helps you reflect on it. Track what you've bought, see how much you saved, and keep an eye on potential savings still waiting in your watchlist. It's not just about chasing deals. It's about making smarter decisions over time. Ideal For: - Building a cross-store wishlist that goes beyond major platforms, covering any retailer you actually shop from - Spotting genuine discounts on products you truly care about - Seeing through deceptive promotions by checking real price history before you buy - Getting alerts only when they mean something, with no unnecessary noise - Anyone who wants a beautifully designed tracker that feels like a proper shopping app - Patiently watching a price until the moment is right to buy - Keeping a clean, organized view of everything you're considering Everything You Need to Shop Smarter - Track any product from any online store - Set target prices and get instant alerts on price changes - View price history to spot genuine deals - Check stock availability alongside price - Score products by quality, value, desire, and priority - Add personal notes to any tracked item - Build and organize a wishlist across any category - Review your purchase history and savings Whisprice is free to download. Premium features are available for shoppers who want to take their wishlist further. Download Whisprice and start shopping with intention.

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.
