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.

Pranix is a breathwork builder and session player for people who take their breathing practice seriously. BUILD YOUR OWN ROUTINES Design routines from scratch using timed breaths, inhale/exhale holds, rest phases, and repeating loops. Every parameter is yours to control — duration, repetitions, structure. The builder autosaves as you work, so nothing is ever lost mid-edit. START WITH EXPERT TEMPLATES Five scientifically-grounded starting points are included: • Box Breathing — 4-4-4-4 pattern for focus and calm • 4-7-8 Breathing — extended exhale hold to promote sleep and relaxation • Tummo Breathing — rapid breathing rounds followed by breath retention • Coherent Breathing — slow 5-second cycles to synchronise heart rate variability • Physiological Sigh — double inhale and extended exhale to rapidly downregulate stress Copy any template, make it yours, or run it as-is. GUIDED SESSIONS The session player features an animated breathing circle that expands and contracts with each phase, clear on-screen phase labels, a progress bar, and haptic pulses on transitions. A 10-second countdown gets you settled before breathing begins. Free holds let you advance at your own pace with a tap. TRACK YOUR PROGRESS Every completed session is saved locally. Your history screen shows total sessions, total minutes breathed, and your longest breath hold — plus a full chronological session log. PRIVATE BY DESIGN All data lives on your device. No account required. No internet connection needed. No subscriptions. Pranix is intended for general wellness use. Always consult a qualified healthcare professional before beginning any new breathwork practice, especially if you have a respiratory or cardiovascular condition.

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.
