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.

Like having a baby sleep consultant in your pocket. OBubba predicts your baby's naps and bedtime from their own rhythm, works out why last night went the way it did, and gives you one thing to change tonight. Then it checks whether it worked. Sleep never happens on its own, so OBubba is also your all-in-one baby tracker for feeds, weaning, teething, milestones, development waves and growth. It uses all of it to understand your baby's sleep. A sore tooth, a new food, a growth spurt or a wave coming up are all part of the picture. One app instead of five. THE SLEEP PROBLEMS OBUBBA WORKS ON • Night wakes, and what is actually driving them • Short naps that never lengthen • Early rising before 6am • Bedtime battles and false starts • Split nights, when a baby is wide awake at 2am • Overtired and undertired days, told apart • Wake windows that no longer fit • Nap transitions, 3 to 2 and 2 to 1 • Sleep regressions and developmental waves LIKE A SLEEP CONSULTANT, ON YOUR SCHEDULE • Nap and bedtime predictions that learn your baby, not an age chart • A daily nap schedule that adjusts as the day unfolds • Gentle sleep coaching plans, including night weaning, at your pace • Night-wake patterns, sleep trends and shareable reports • Ask Luna, OBubba's warm AI parenting friend, about sleep, feeds or development at any hour EVERYTHING ELSE THAT CHANGES SLEEP • Feeding: breast, bottle, pumping and solids, with one-tap logs and timers • Weaning: first foods and allergen guidance • Teething: log each new tooth and see sore nights in context • Milestones and development waves, with age-right activities • Growth tracking, diapers and medicine logs PREGNANCY, MADE MAGICAL Follow all 40 weeks with weekly baby stories, size comparisons, preparation tools, kick and contraction counters, checklists and keepsakes. SHARE CARE Keep partners, grandparents, carers and daycares in the loop with BubbaCare handovers, shared updates and clear summaries. MADE FOR TIRED PARENTS Day and night modes, large clear controls and a calm design make 3am logging quick and kind. OBubba Premium adds deeper sleep guidance, personal rhythm insights, trends, reports, sharing, weaning tools, memory book features and more. OBubba is not medical advice and does not diagnose or treat health or sleep conditions. Always speak to your midwife, pediatrician, doctor or qualified professional for medical concerns. No ads. No selling your data. Just a softer way to keep the day together. Subscription terms: Auto-renewable subscriptions renew unless cancelled at least 24 hours before the end of the current period.

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.
