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.

TipStash is a private tip tracker and shift income calculator for servers, bartenders, baristas, and anyone who earns tips. Log cash and card tips, paid hours, wages, tip-ins, tip-outs, other income, and work expenses. TipStash turns every saved shift into a clear view of your net tips, total earned, cash in hand, and effective hourly rate. LOG A SHIFT YOUR WAY • Start a live shift and add tips as you earn them • Log a past shift with only tips and hours, then add details when you need them • Keep cash, card, tip-in, and tip-out amounts separate • Save a draft stash when you want to add hours later SEE WHAT YOUR WORK WAS WORTH • Calculate net tips, base pay, total earned, cash in hand, and effective hourly rate • Keep each shift’s wage and currency with that record, so later changes never rewrite history • Track multiple jobs, roles, wages, and supported currencies • Add sales, other income, expenses, and notes when they matter FIND ANY SHIFT FAST • Browse a clear calendar of daily earnings • Open and edit saved shifts from your history • Keep deleted shifts out of totals instead of losing them immediately • Import a CSV backup or another tracker’s history, then export whenever you need it • Recover old quick-tip rows into clear unfinished drafts instead of misleading zero-hour history entries BUILD A PRIVATE SHIFT HABIT • Set an optional weekly earnings goal and see a calm weekly recap, best saved shift, and transparent monthly pace • Add a pay-period start day when you want a paycheck-aligned view • Save a shift template for the job, hours, wage, and tip-out you repeat most • Choose one useful reminder for an unfinished shift—never a streak or repeated nag PRIVATE BY DESIGN • No account required • No ads or third-party analytics SDKs • Keep records on your device by default • Optionally use Face ID lock, amount hiding outside the app, and iCloud sync USEFUL WITHOUT THE FRICTION • Start a shift, add a preset cash or card tip, or undo the last quick tip from the Home Screen widget • Configure a widget for a job and its common amounts • See your live shift on the Lock Screen, Dynamic Island, and Live Activity • Use Siri Shortcuts and supported Control Center controls for start, add-tip, and finish actions • Use the simple essentials first; advanced fields stay out of the way until you open them TipStash is not a bank, payroll service, or tax-advice app. It is the simple, private place to keep a trustworthy record of what each shift earned.

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.
