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.

See the time, hear your next step, walk out the door on time. Cuebird turns any routine (morning, lunch break, bedtime) into small, timed, color-coded steps and moves you through them automatically. Now the people you live with can do it with you. Built for neurodivergent adults. Kind to every brain. DO IT TOGETHER Link the people you live with into a household. Start a routine for your household and everyone gets a gentle offer to jump in, landing exactly where you already are rather than back at step one. Joining is one tap and sitting one out is free: nobody is ever told either way. Be in more than one household at once, your own and the one at your mum's, and every routine says which one it came from. It all travels through your own iCloud. Cuebird has no servers and cannot read any of it. TIME YOU CAN SEE While a routine runs, the whole screen becomes the current step's color. From across the room, mid-shower, without reading anything: blue means shower, amber means coffee. Every routine also shows a color bar of its steps, so you can see the shape of your time before you start. OUT THE DOOR ON TIME Set when a routine starts and when you have to be done. Cuebird shows the window, adds up your steps, and tells you plainly whether they fit. Running late? One control compresses the whole routine proportionally so you still walk out on time. HEAR YOUR NEXT STEP A chime marks every transition, or let Cuebird speak: "Next: Shower, 10 minutes." A wrap-up warning gives a 30-second heads-up before longer steps end. Prefer quiet? Silent mode keeps it to haptics. You can also record any step in your own voice. Recordings stay on your device. REAL ALARMS, NOT NOTIFICATIONS Give a routine a start time and days, and it rings with the system's full-screen alarm: through silent mode, through Focus, even with the app closed. Tap Start and you're already in the routine. BUILT THE WAY YOUR WEEK ACTUALLY WORKS One routine can ring at several times, each with its own days: weekdays at 7:00, weekends at 9:00. Your list sorts itself around today, with the next one badged. The Schedule view shows everything that will ring this week. REUSE WHAT REPEATS Build a group of steps once, link it into every routine that needs it, and change it in one place. IT LEARNS YOUR REAL TIMING Cuebird records every run and shows how long your routine ACTUALLY takes versus what you planned: "Morning really takes 42 minutes, not 35." It shows which step you skip most and where you run over, then updates your plan with one tap. STARTING IS ONE TAP Every routine has a play button right on its card. No menus between you and momentum. Or let a real alarm start it. For the times you do not need a whole routine, Quick Timer and Ring Me At are one tap away. NO SHAME BUILT IN Pause says "no rush." Skipping is a first-class button, and if you skipped by mistake you can undo it. Need a minute back? Take one. Finishing celebrates every single run, and one missed day never breaks your streak. That is what the habit-formation research actually says. Cuebird never scolds you. EVERYWHERE YOU NEED IT • Lock Screen and Dynamic Island Live Activity: glance without opening the app • Home Screen widget: start a routine in one tap • Apple Watch: your step and countdown on your wrist, and pause, resume or skip from there • Siri and Shortcuts: "Start Morning in Cuebird," or trigger routines from your automations • Mac: runs on Apple silicon Macs too BUILT TO BE KIND • Break routines into steps as small as "put on socks" • Your routines sync via your own iCloud: no account, no login, ever ONE PURCHASE COVERS YOUR FAMILY Family Sharing is on, so up to six family members get Cuebird with one purchase. You can also send any routine as a link, ready for their own times. ONE-TIME PURCHASE Buy it once. No subscription, no ads, no accounts, and no data collection. Your routines never leave your device and your own iCloud.

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.
