Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
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
The fastest way to get from a symptom to the command that fixes it. Type "cannot connect to the network" into the search box. A diagnostic flow opens with ping, ipconfig, nslookup and tracert laid out in the order you actually run them. You don't need to remember the command name. ■ Fully offline All 882 commands live on your device. Server rooms with no signal, air-gapped networks, a customer site with the Wi-Fi down. The moments you most need to look up networking are the moments the network is broken. Nothing is transmitted, ever. ■ 75 troubleshooting flows "PC is slow." "Mail not arriving." "Port already in use." "Clock drift." Enter the symptom and get an ordered set of steps, each with the command to run at that step. Less time guessing where the fault is. ■ Search that forgives Type "ipconfog" and it suggests ipconfig. Search by alias, not just by name. Filter chips narrow results to Linux, Windows, Cisco and the rest in one tap. ■ Spotlight Swipe down on your home screen, type "netstat", jump straight to the entry without opening the app. ■ What's inside · 882 commands across 15 platforms Linux 178, Windows 107, PowerShell 89, Kubernetes 53, macOS 52, Git 52, Cisco 48, Cloud 48, SQL 44, Docker 41, Active Directory 40, Microsoft 365 36, Virtualization 36, FortiGate 31, Yamaha 27 · 75 troubleshooting flows · Worked examples and syntax for every command · Destructive commands clearly flagged ■ Premium (one-time purchase) · All 75 troubleshooting flows (2 free) · Unlimited favorites (10 free) · iCloud sync · Personal notes on any command · Export Not a subscription. Buy once, that's it. ■ Privacy No account. No ads. No tracking. The developer receives none of your data. The app is offline, so there is nothing to send. ■ Languages App interface and symptom search: English, Japanese, Spanish, German, French, Portuguese, Simplified Chinese, Traditional Chinese, Korean. Command explanations and flow text: English and Japanese only. ■ Please note Content is reference material. Run commands at your own discretion and risk, ideally in a test environment and after taking backups. Built by an in-house IT engineer who wanted this on his own phone. Feedback is welcome from inside the app.

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.

Intermediate
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.
