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.

Your tasks and your calendar, finally in one calm view. Most planning apps make you choose: a to-do app that treats your calendar as an afterthought, or a calendar that bolts on tasks. The few that truly combine both cost a fortune and make you learn a whole method first. Soothy takes the opposite path. One screen shows what you have to do AND what's happening today, blended together, or filtered apart when you want to focus. No method to learn. No monthly bill. It just works, the moment you open it. TASKS, SORTED FOR YOU • Drop in a task, it files itself: overdue, today, or upcoming • Colors tell you everything at a glance: red, blue, orange • Natural-language entry: "dentist tomorrow 9am" • Capture inbox for fleeting thoughts and links • Custom sections and recyclable checklists A REAL CALENDAR, BUILT IN • Month and week views, your events and tasks together • Two-way sync with your iOS calendars • Create and edit events without leaving the app • Search your full history, 25 years back, instantly • Choose exactly which calendars to show EVERYWHERE YOU ARE • iCloud keeps everything in sync BUILT THE RIGHT WAY • No subscription. Ever. One-time purchase, updates included. • No account, no analytics, no tracking. Your data stays in your iCloud. • Full VoiceOver, Dynamic Type and Reduce Motion support • Available in 6 languages Soothy is for people who just want to see what's today, what's coming, and what's done — calmly, without the setup. https://soothyapp.com/privacy.html

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.
