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.

Tinnitus on your terms. Experience the first Augmented Reality game designed specifically for people with tinnitus. Freequency combines science, technology, and gameplay in one innovative app to help you gain more control over your tinnitus. As the very first app to apply mirror therapy and exposure techniques within an Augmented Reality environment, Freequency offers a unique way to localize the sound of your tinnitus and gradually move it into the background—without medical devices or expensive treatments. What is tinnitus, and how does Freequency help? Tinnitus results from a neurological process in which your brain generates sounds without an external source. By training your brain in a playful and engaging way, you can learn to reduce the impact of tinnitus and find better balance in your daily life. Why choose Freequency? Safe and easy for everyday use: • Designed by experts: Developed in collaboration with professionals such as Tricia Scaglione, AuD, MBA and Dr. Steven C.

Two ways to practice: • Catch the Tone: Find the birds carrying your tinnitus tone in your own room with Augmented Reality and spatial audio, then catch them one by one. • Soundscape: Sit back while your tone gently drifts from ear to ear—a calm session for days when you want to take it easy. Unique features of Freequency: • Tone matcher: Match your tinnitus precisely with eleven waveforms and noise colors—including white, pink, and brown noise—and mix several tones at once. • Hearing test: Screen your hearing per ear and keep your audiogram results in the app. • Journal with insights: Charts of your intensity and practice time, plus a weekly analysis of your progress. • Lifestyle check-in: Log how you slept, ate, and moved, and discover how those patterns relate to your tinnitus. • Search: Find any video, article, or tone across the app in seconds. • Apple Watch and widgets: Your streak, statistics, and running session on your wrist, Home Screen, Lock Screen, and in Control Center. • Community: Articles and updates from the experts behind Freequency. • Personal touches: Your own avatar, reminders, subtitled videos, Siri shortcuts, and iCloud sync across all your devices. What can Freequency do for you? • Reduce the impact of tinnitus. • Improve focus and reduce stress. • Train your brain to filter tinnitus into the background. • Increase calm, balance, and quality of life. Try Freequency today! Take the first step toward greater control over your tinnitus. Practice at your own pace, with an innovative approach that fits seamlessly into your daily routine. Subscriptions, availability, and functionality: A subscription is required for the full experience, including personalized exercises, AR features, and detailed progress insights. Free users have access to the Tone Matcher and introductory content to explore Freequency. Some features are only available in certain regions. Subscriptions renew automatically unless canceled before the end of the current billing period. To try Freequency risk-free, we offer a free trial. More information is available within the app. Freequency is designed to support people with tinnitus in managing their symptoms, but it does not replace professional medical advice, diagnosis, or treatment. If you have questions or concerns about tinnitus or your health, always consult a physician or audiologist. Use of Freequency and the information provided in the app is at your own risk.

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.
