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.

Phone calls made accessible. Rylo provides real-time, AI-powered call captions on every phone call for anyone who is deaf or has hearing loss. Captioned calls are private and accurate. MAKE AND RECEIVE ANY CALL Rylo works like your native phone app, but with speech-to-text call captions. If you prefer to type your responses, you can choose a voice and use our text-to-speech feature. No interpreters. No relay services. No strangers listening in. LIVE CAPTIONS FOR REAL LIFE Our built-in feature, Rylo Live Transcribe, captions in-person conversations instantly: family dinners, doctor's appointments, airports, or anywhere else you don't want to miss a word. YOUR PRIVACY IS PROTECTED Captions are generated with end-to-end encryption. No human involvement. No one reading your calls but you. BUILT FOR THE DEAF COMMUNITY, BY THE DEAF COMMUNITY Rylo was built with direct input from the Deaf and hard of hearing communities. Every feature exists because someone in the community needed it. Accessibility matters. KEY FEATURES ■ Live caption calls with transcripts ■ Live captioning for in-person moments (Rylo Live Transcribe) ■ Personal dictionary for custom words and phrases ■ Quick keyboard responses as needed ■ Visual voicemail ■ Save transcripts privately on your device ■ Multilingual captioning: English, Spanish, French, Japanese, Hebrew, Italian ■ Built-in spam filter and call blocking ■ Profanity blocker ■ FCC certified "Rylo is the true definition of a game-changer. Their goal is to ensure effective and smooth communication." — Verified user "I was able to make a phone call myself. I set up my own appointment. I could clearly read every word the recipient was saying to me. I explained to her I was deaf and I was using closed captioning. It was amazing. Thank you Rylo for allowing me to be more independent." — Verified user Download Rylo. Make calls with confidence. For more: https://rylo.com/ Support: https://help.rylo.com/en/ FEDERAL LAW PROHIBITS ANYONE BUT REGISTERED USERS WITH HEARING LOSS FROM USING INTERNET PROTOCOL (IP) CAPTIONED TELEPHONES WITH THE CAPTIONS TURNED ON. There is a cost for each minute of captions generated, paid from a federally administered fund. There are also eligibility requirements and a cost, paid by a federally administered fund for each minute of IP Relay service. Emergency calling through Rylo works similar to, but not the same as, calling 911 directly through a landline. It is important to keep your Rylo Registered Location updated.

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.
