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.

Track your baby's sleep, feeding, diaper changes, pumping, and mood. Now you have an assistant on your journey to mindful parenting – trusted by 100,000+ moms and dads! Grow Together. Every Step of the Way. GROWTH CRISES CALENDAR From birth up to 2 years, a child goes through several growth and development crises. There's no need to be worried – this is a natural process during which the nervous system and brain develop, and the baby acquires new skills. However, during such periods, a child might become fussy and sleep poorly. We display growth crises in the calendar so you won't worry: together with pediatricians we explain what's happening with the physiology, motor skills, and speech development of your child up to 105 weeks. HEIGHT, WEIGHT, AND CIRCUMFERENCE MEASUREMENTS Fix key child's growth parameters – and track how they change. Check them against the World Health Organization's standards. TRACKERS FOR SLEEP, FEEDING, DIAPER CHANGES, PUMPING, AND CHILD'S MOOD Record all the important information about your child's daily schedule and routine – all in one app. 230+ DEVELOPMENTAL EXERCISES FOR EVERY DAY Tiger on a Branch, Maracas, More Noise, Miracles – these are not the colorful titles of children's cartoons, but engaging developmental exercises that you can perform with your child every day. JOURNAL OF PRECIOUS MOMENTS Your little one’s first smile, their first tooth, the momentous first step – record these lovely memories not just in your heart. Log them in the app to create a cute video and share it on social media and messengers with family and friends. SUBSCRIPTION INFORMATION The subscription provides access to additional services in the app, becoming your daily go-to parenting resource. — A set of daily exercises that matches the stage of your baby's development and doesn't take much time.

I learned about growth crises and how challenging they can be for both the child and parents. To keep track of them, I created this app. Suddenly other parents started using it too. Today, thousands of moms and dads monitor their child's development with us – it's so inspiring, I'm so grateful. Thank you! Growing up is not easy! But we love supporting parents and children every day on this exciting journey. Privacy Policy: https://sprouty.app/privacy-policy Terms of Use: https://sprouty.app/terms-of-service

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.
