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

For John Daido Loori Roshi "The zazen I speak of is not learning meditation. It is simply the Dharma Gate of repose and bliss, the practice/realization of total accumulated enlightenment." ——— Tōki — time, and the vessel that holds it. Your meditation practice deserves better than a stressful countdown clock. Tōki replaces it with something far more human — a beautifully animated incense stick that glows and slowly burns as you sit, letting you feel the passage of time rather than watch it tick away. The smoke curls. The ember dims. Time becomes something you inhabit, not something you race against. And for those moments when you do need the number? It's a tap away. To begin, trace the Ensō to set your duration — anywhere from a one-minute breathing reset to a full sixty-minute sit. An interaction designed to feel like it belongs in the practice itself. Whether you're finding your footing or deepening a years-long practice, Tōki gets out of your way. It comes out of 35 years of practice, 16 of them living at a Zen Monastery. ——— FEATURES • Pay Once, Yours Forever A single, one-time purchase. No subscriptions, no ads, no hidden fees — ever. • The Incense Timer A gently glowing stick burns down in real time as you sit. No digits, no anxiety — just a calm, organic visual that lets you sense the passage of time at a glance. • Trace the Ensō Draw the ancient Zen circle to set your session length. An interaction as intentional as the practice it begins. • Acoustic Opening Instruments Every session opens with a choice: the bright, piercing strike of the inkin — the small bell whose single note cuts cleanly through distraction. Or the han — that unmistakable twock of wood on wood, the sound that marked evening sitting at the Monastery, the closing of the day, stillness punctuated and gathered in. Or the temple bell — this world is vast and wide. Why take your seat at its sound? Every session closes with the traditional inkin. • Warm-Up Phase A brief, customizable settling period before your session officially begins. Time to adjust your posture, soften your gaze, and land. • Widgets — Lock Screen & Home Screen Glance at your streak or active countdown from your Lock Screen. From your Home Screen, dive straight into a 5 or 15-minute session with a single tap — perfect for a quick reset between meetings. • Apple Health Integration Sessions are automatically logged as Mindful Minutes in Apple Health. Your wellness data stays complete without any extra effort. • Runs in the Background Lock your screen, put your phone face-down, and forget it's there. Tōki runs silently — then gently calls you back with the closing bells when your session is complete. • Practice Insights Your current streak, longest streak, and total sessions — quietly recorded so you can watch a practice become a ritual. • Show or Hide the Countdown The incense burns whether you watch the numbers or not. Toggle the display off for a completely bare, number-free screen. ——— Take a deep breath, trace your Ensō, and begin.

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.

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.
