A product spec, screen plans, and build steps for your coding agent.

Generating… usually about a minute.
What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
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.
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.

### Featured in TED Blog: “25+ apps to make your everyday life easier” ### Capture a thought, to-do, or scrap of information, FAST! MeMail does one thing exceptionally well: send quick emails to a pre-set address. Email yourself reminders or notes? Just launch, type, and send — that's it! No fishing around for the right contact. Simply set your address the first time you open the app and you’re good to go. FEATURES: • Email messages are sent from your own account — they come from *you*, not a third party. • Full subject-line control: Enable "AutoSubject" to add the first few words of your message to the subject line, or just use a custom prefix like "[MeMail]" so your messages stand out in your Inbox. You can use or both, or neither — or even change the subject manually before the message goes out — it’s up to you! • Optional Subject Suffix setting • Optional Cc: address setting • Supports TextExpander 3.5.4 snippet expansion, including fill-in forms • Optimized for iPhone 6 and 6 Plus • One-Tap Send: Enter the settings for the mail account of your choice if you’d like to bypass the standard message screen and make MeMail even faster. TIPS: • MeMail is great for sending emails to yourself, but many find it invaluable for other uses. Set your significant other for quick "ETA" messages, use an Omni Mail Drop address and have your messages appear automatically as tasks in OmniFocus — if you can do it with email, you can do it faster with MeMail.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
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.
