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

Follow the market. Know your portfolio. Stock Master brings real-time US stock quotes, watchlists, portfolio tracking, price alerts, and advanced charts together in one app. Follow pre-market and after-hours moves, research opportunities, and practice trading strategies from your phone or tablet. Whether you’re watching a few favorite stocks or managing multiple portfolios, keep the information you need close at hand. === Real-Time Stock Quotes & Watchlists Follow stock prices, pre-market and after-hours trading, company news, and key statistics including market cap, volume, P/E, and EPS. Organize stocks into multiple watchlists. Real-time quotes are available for US markets; other exchanges and data feeds may be delayed. === Portfolio Tracking See what you own and how it’s performing. Track open and closed positions, transactions, commissions, dividends, stock splits, and holdings in multiple currencies. Export your portfolio to Text, CSV, PDF, or Excel. Sign in to back up and sync your data. === Customizable Alerts Let Stock Master monitor the market for you. Create alerts for price levels, daily changes, volume, trailing stops, and technical-indicator trends. Receive push notifications when your conditions are met, with a choice of alert sounds. No account required. === Advanced Charts & Technical Analysis Explore price history with interactive line, candlestick, and OHLC charts. Add indicators including moving averages, MACD, RSI, Bollinger Bands, and Stochastic, plus candlestick-pattern overlays. Draw trend lines, Fibonacci retracements, and channels, or replay historical price action. === Trendscore & Backtesting Find stocks to research with Trendscore, which ranks technical trend strength using backtested strategies. Explore momentum and swing-trading candidates, then test your own strategies against historical data. Past performance does not guarantee future results. === Stock Screener Narrow your search with fundamental and technical criteria across markets including NYSE, NASDAQ, AMEX, TSX, ASX, LSE, NSE, and NZX. Save your screens and run them again as conditions change. === AI-Powered Research Get AI-generated analysis for individual stocks or your portfolio, and explore follow-up questions with Finabase AI chat. AI content is informational and may contain errors; it is not personalized investment advice. === Market News & Global Markets Read business and financial headlines alongside your market research. Monitor major indexes, futures, forex, US Treasury yields, commodities, ETFs, options chains, earnings calendars, and cryptocurrencies. Data availability and delays vary by market. === Home-Screen Widgets Keep your watchlists, portfolio summaries, market heat maps, and index comparisons within reach without opening the app. === Virtual Trading & Community Practice with virtual funds and real market quotes. Track simulated trades, explore strategies, and join discussions with other investors. Stock Master does not execute real-money trades. === Premium Subscriptions Remove ads and unlock additional capabilities with Essentials, Plus, or Premium subscriptions, available monthly or annually.

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.
