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.

Return to focus. MONO is an interactive attention laboratory. Follow a moving dot, listen as a tone fades, or return to the rhythm of your breath. Choose a practice. Give it a minute or two. When your attention wanders, come back. PRACTICE YOUR ATTENTION • Follow the dot — stay with one moving point and its flowing ribbon. • Eye of the storm — keep one shape in view as others drift past. • Room to breathe — settle into a gentle breathing rhythm. • Afterimage — remember a sequence through a wash of color. • Sound thread — follow one tone among competing sounds. • Last sound — follow the global melody through its swells, fades, and quiet spaces. • Slow orbit — trace a dotted ring and gradually bring out singing harmonies. • Between the lines — stay with one signal in a shifting circle of color. • Color drift — return to one part of a living, responsive field. • Color cadence — follow a color through changing movement and musical cues. • Undertone — learn a tone, then find it among other sounds. • Bubble bath — return to the center as a field of colorful bubbles moves around it. MAKE IT YOURS Start with a three-minute Daily reset that begins with the featured Home artwork, or choose a 60-, 90-, or 120-second practice. Create your own playlists, choose their order and duration, and begin each practice when you are ready. Shape an original ambient soundscape with a finger: airy, warm, melodic, or gently percussive. Sound and timed practices pause when you lock your device or leave the app. Soft motion, responsive touch, and carefully placed haptics give each practice its own character. Adjust sound, volume, haptics, and motion to suit the moment. TAKE IT WITH YOU A short, interactive introduction welcomes you to MONO. Replay it from Settings whenever you like. Before you begin a practice, a short reminder offers a different perspective. After each practice, see what you practiced and one small way to carry it into your day. Save a reflection. See the days you returned in your weekly practice wheel. Add the wheel to your Home Screen, with a fresh daily quotation in the medium widget. Tap to open Your practice. Build a rhythm at your own pace. PAY ONCE One purchase includes unlimited use of every public practice and the updates released for MONO. No subscription or in-app purchases. Your journal and playlists stay on your device. Optional anonymous usage analytics help us understand which practices people start and finish. Turn sharing off in Settings at any time.

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.

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.
