Your first Build Kit is free with a verified email.
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.

Stillwave is a calm, ad-free tinnitus management app designed by an Australian Accredited Audiologist. It brings together evidence-based tools to help you reduce the impact of tinnitus over time, without subscriptions, ads, or gamification. SOUND THERAPY MIXER Layer eighteen sounds including brown noise, pink noise, white noise, ocean waves, rain, waterfall, babbling brook, thunderstorm, and ambient sounds. Save your mixes, adjust stereo balance per ear, and set a sleep timer with automatic fade-out. FREQUENCY TOOL Match the pitch of your tinnitus from 250Hz to 16kHz using a manual sweep or guided A/B matching. Helpful for understanding your own tinnitus and for explaining it to others. EIGHT-WEEK PROGRAM 56 lessons over eight weeks, designed specifically for people with tinnitus. Week 1 is understanding. Week 2 is sound therapy. Week 3 is CBT. Week 4 is sleep. Weeks 5 to 8 are concentration, communication, habituation, and long-term maintenance. Each lesson combines a short education piece, a structured timed practice, and a reflection prompt. EXERCISES AND GUIDED MEDITATIONS Thirteen guided practices: eight CBT and breathing exercises including 4-7-8 Breathing, Box Breathing, Thought Defusion, Body Scan, and Sound Acceptance; and five guided meditations read aloud automatically, designed for eyes-closed practice. CHECK-IN A 14-question self-check that helps you track tinnitus impact across four areas: Awareness and Loudness, Sleep and Rest, Daily Function, and Mood and Coping. Add notes to each entry and see your progress over time. The goal is habituation, helping your brain respond to tinnitus with less distress, not eliminating the sound itself. Most people improve with consistent use over months. Stillwave is a toolkit you can return to whenever you need it. PRIVACY Stillwave runs entirely on your device. There are no accounts, no servers, no analytics. Your check-in scores, saved mixes, and notes never leave your phone. PRICING One-time purchase. Full access. No subscription. HOW IT IS DIFFERENT Built by a clinician, not a corporation. The content reflects years of audiology practice, not a marketing team. Honest framing: tinnitus does not currently have a cure. Stillwave is built around habituation, the evidence-based process by which the brain learns to treat tinnitus as less significant. No gamification, no streaks, no daily engagement nudges, no manipulative design. The goal is your wellbeing, not your screen time. IMPORTANT Stillwave is a wellness app, not a medical device. It is designed to complement clinical care, not replace it. If you are newly diagnosed or have concerns about your hearing or tinnitus, experience sudden hearing loss, severe vertigo, or pulsatile tinnitus, please consult your audiologist or GP. These can be signs of conditions requiring medical attention. stillwavetinnitusapp.com

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.
