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.

WHY VAGUSCALM? Most apps ask you to breathe or meditate when you're already spiraling. We know that's hard. VagusCalm offers a tactile anchor. By feeling a rhythmic, steady pulse in your hand — now with an optional heartbeat sound to match — you give your brain a physical signal of safety, promoting an immediate vagus nerve reset. INSTANT RELIEF FOR STRESS, PANIC & ANXIETY Reset your nervous system with the power of somatic grounding. VagusCalm uses a scientifically inspired heartbeat you can feel and hear to pull you out of "fight or flight" and back into the present moment. KEY FEATURES FOR STRESS RELIEF: • Realistic Haptic Pulse: Vibration patterns designed to feel like a calm, resting heartbeat. • Optional Heartbeat Sound: Hear the pulse through headphones or your speaker, layered with the haptics. • Somatic Grounding: A physical tool for high stress, sensory overload, and trauma responses. • Vagus Nerve Stimulation: Supports your vagal tone through rhythmic feedback. • Customizable BPM: Find the rhythm that feels safest for you. 30–60 BPM in Classic Mode. • Sessions Mode: Pick a preset or build your own personalized calm-down routine. • Background Ready: Screenlock feature to put the phone under your pillow or in your pocket. PERFECT FOR YOUR JOURNEY: • Stopping a panic attack before it peaks. • Managing social anxiety in public (completely discreet). • Quieting racing thoughts before sleep. • A mindful alternative to voice-guided apps. PRIVACY-FIRST ANXIETY SUPPORT: • No account or login required. • No data collection or tracking. • 100% Offline (Works everywhere). • No ads, no subscriptions. SCIENCE-BACKED GROUNDING VagusCalm works with interoception — the way your brain constantly reads signals from your body to decide how you feel. Give it a slow, steady pulse to read, and it has something calm to work with. It's a simple, powerful way to regain control when things feel overwhelming. Note: VagusCalm is a wellness tool for relaxation and grounding, not a substitute for medical treatment.

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.
