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.

DidYou? is the failsafe reminder app that refuses to be ignored. Most reminder apps send a quiet ping and hope for the best. DidYou? is built for people who actually need to remember — athletes, busy professionals, caregivers, and anyone whose day depends on never missing a beat. WHAT MAKES DIDY0U? DIFFERENT When your alarm fires, DidYou? doesn't just vibrate. It speaks to you. It flashes your screen. It shakes your phone continuously. It plays your custom audio. All at once, until you hit the giant STOP button. VOICE-PROMPTED INTERVAL TIMER The only interval timer that coaches you out loud. Set your work and rest durations, choose 1–10 cycles, and let DidYou? count you in with '3... 2... 1... Go!' — then count down every second so you never have to glance at your screen. FAILSAFE FEATURES → Voice Reminders — speaks your custom message using any iOS voice → Continuous Haptics — your phone pulses until you respond → Flash Alerts — screen strobes to grab your attention → Custom Alarm Sounds — import your own .mp3, .wav, or .m4a → Critical Alerts — bypass silent mode entirely (with permission) → Daily Repeating Tasks — set it once, fire every day → Calendar Integration — pull in events and add reminders in one tap PERFECT FOR • Gym-goers tracking intervals and rest periods • Professionals with back-to-back meetings • Anyone who leaves their phone on silent • Caregivers managing medication schedules • Students who lose track of time studying

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.
