Generating… usually about a minute.
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.

Follow your pregnancy week by week with a pregnancy tracker designed for expecting mothers. Monitor your baby’s development, understand changes in your body, calculate your due date, track important health information, and prepare for childbirth — all in one app. PERSONALIZED PREGNANCY TRACKER See how your baby grows during every week of pregnancy. Learn about fetal development, your baby’s size and milestones, and the physical and emotional changes you may experience in each trimester. Receive personalized pregnancy tips about nutrition, lifestyle, prenatal health, and preparing for birth. PREGNANCY CALENDAR Use the pregnancy calendar to follow your gestational age, current trimester, and estimated due date. Schedule prenatal appointments, doctor visits, screenings, ultrasound scans and tests. Timely reminders help you stay organized throughout your pregnancy journey. PREGNANCY DIARY AND HEALTH TRACKER Keep a personal pregnancy diary and record your daily symptoms, mood, weight, blood pressure, belly growth, physical activity, and other health information. Track changes over time and keep important details ready for your next prenatal appointment. WEEK-BY-WEEK BABY DEVELOPMENT Discover what happens with your baby each week — from early fetal development to the final stages before delivery. Compare your baby’s size with familiar fruits and objects. BABY KICK COUNTER Track your baby’s movements with a convenient kick counter. Record kicks and activity sessions to better understand your baby’s movement patterns during pregnancy. CONTRACTION TIMER Use the contraction timer and counter to record the duration, frequency, and intervals between contractions. Follow your contraction pattern and distinguish practice contractions from possible signs of labor as you prepare for childbirth. DUE DATE AND GESTATIONAL AGE CALCULATOR Calculate your estimated due date, gestational age, current pregnancy week, and trimester. The pregnancy calculator helps you understand how far along you are and follow the timeline leading up to your baby’s birth. DAILY PREGNANCY ARTICLES Explore helpful articles about pregnancy symptoms, baby development, prenatal care, nutrition, emotional well-being, relationships, labor, delivery, and postpartum preparation. New educational content provides practical support for expecting mothers. DOCTOR REPORT Combine your pregnancy diary, weight, blood pressure, symptoms, and other tracking data into a clear report. Save the report as a PDF or show it on your phone during a doctor visit to discuss your pregnancy progress. CHECKLISTS AND TO-DO LISTS Organize prenatal appointments, tests, essential purchases, hospital bag items, birth preparation, and other tasks before your baby arrives. KEGEL EXERCISES Practice guided Kegel exercises to support pelvic floor health during pregnancy and help your body prepare for childbirth.

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.
