Your first Build Kit is free with a verified email.
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.

Snowball shows you what your dividends turn into if you keep reinvesting them. Put in what you have, what you add each month, and what your portfolio yields. Snowball projects your dividend income year by year - and puts the answer on your home screen. WHY REINVESTING MATTERS A dividend you spend is income. A dividend you reinvest buys shares that pay their own dividends, which buy more shares. That compounding is hard to picture and easy to underestimate. Snowball makes it concrete: flip reinvesting off and see exactly what the same money would have done instead. WHAT YOU GET - Your projected annual and monthly dividend income, year by year, on a clear chart. - Portfolio value, total contributed, and growth kept separate, so you can see how much came from the market and how much came from you. - Yield on cost, which rises over time as the dividend grows against what you originally paid. - An income goal: set a target and Snowball tells you which year you reach it, or says plainly that you do not at these numbers. - A home-screen widget showing your projected income. Long-press it to change the assumptions - you never have to open the app. BUILT PROPERLY Value and income are modelled separately, month by month, so growing dividends and rising share prices are treated as the different things they are. Contributions start earning at your yield the month they land. Reinvested dividends buy income of their own. That is the snowball. HONEST ABOUT WHAT IT IS This is a projection from numbers you enter, not a forecast and not financial advice. Real dividends get raised, cut and taxed, and real share prices do not move in straight lines. Snowball shows you the shape of compounding so you can reason about it, not a promise. NO STRINGS One purchase. No account, no subscription, no ads, no tracking. Nothing leaves your phone. From the makers of DivTrkr, the free dividend tracker at divtrkr.com.

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.

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.
