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.

Take Control of your routines, no matter how your day flows Time Stream allows you to see how your routines and their activities flow with and around your calendar events, sleep schedule, and important times throughout the day in a single, visual timeline. Especially great if, like the developer team, you could use some help with time perception, establishing consistent routines, or balancing complex schedules. Establish consistent routines that stick * Create customizable morning, evening, and custom routines * Sequence activities with estimated durations * Mark activities complete, skip non-essential tasks, or reset progress * Pause and resume routines when interruptions occur See how your time flows * View dynamic completion estimates that update in real-time * Track progress with intuitive visual indicators * Receive warnings when activities exceed estimated duration * Understand exactly how your day is progressing at a glance * Monitor time between activities with buffer visualization Harmonize all of your time commitments * Integrate with your device calendars * Visualize how routines fit around existing calendar events * Set critical time thresholds with visual conflict warnings * Define wake and bed times * Get warnings if your routines might interfere with your planned sleep schedule Designed with accessibility in mind * Multiple colour themes and appearance options * Light/dark mode support * Reduced cognitive load through visual cues * ADHD-friendly interface with clear sequential progress * Privacy-focused with local-first data storage Built to provide the structure and visual clarity needed to transform how you interact with your time, your most precious resource. (And if you’re a Beeminder user, you can sync your activity completions to your Beeminder goals)

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.
