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.

CircleTrack is the simplest way to run a savings circle — known as a ROSCA, tanda, SAN, Partner Hand, susu, or chit fund — right from your phone. Whether you manage a group of 5 or 50, CircleTrack keeps every contribution, cycle, and member in one place so you never lose track of who paid, who's late, and who receives the pot next. KEY FEATURES • Multiple circles — Run as many savings circles as you need, each with its own schedule, contribution amount, and member list. • Flexible frequency — Weekly, biweekly, or monthly cycles to match your group's rhythm. • Payment tracking — Record payments with a single tap. See paid, pending, and late status for every member, every cycle. • Pot dashboard — Know instantly how much the pot is worth this cycle, who receives it, and your overall collection rate. • Member reliability ratings — Each member gets an automatic score based on their on-time, late, and missed payments — so you always know who to trust. • English / Spanish — Switch the entire app between English and Spanish at any time from settings. Spanish is the default. • Secure sign-in — Sign in with Google or Apple. Your data is private and synced securely to your account. • Face ID / Touch ID — Authenticate instantly with Face ID or Touch ID on every session. CircleTrack works for every tradition: Mexican tanda, Dominican san, Caribbean Partner Hand, West African susu, South Asian chit fund, and more. If your community pools money in rotating cycles, CircleTrack is built for you. CircleTrack es la forma más sencilla de administrar tu tanda — también conocida como ROSCA, SAN, Partner Hand, susu o chit fund — directamente desde tu teléfono. Ya sea que manejes un grupo de 5 o 50 personas, CircleTrack mantiene cada aportación, turno e integrante en un solo lugar para que nunca pierdas de vista quién pagó, quién se atrasó y quién recibe el bote. FUNCIONES PRINCIPALES • Varias tandas — Administra todas las tandas que necesites, cada una con su propia frecuencia, monto de aportación y lista de integrantes. • Frecuencia flexible — Turnos semanales, quincenales o mensuales según el ritmo de tu grupo. • Control de pagos — Registra pagos con un solo toque. Ve el estado de pago — pagado, pendiente o atrasado — de cada integrante en cada turno. • Tablero del bote — Sabe en todo momento cuánto vale el bote de este turno, quién lo recibe y tu tasa de cobro general. • Calificaciones de confiabilidad — Cada integrante obtiene una calificación automática basada en sus pagos a tiempo, tardíos y perdidos — para que siempre sepas en quién confiar. • Inglés / Español — Cambia el idioma de toda la aplicación en cualquier momento desde ajustes. El español es el idioma predeterminado. • Inicio de sesión seguro — Inicia sesión con Google o Apple. Tus datos son privados y se sincronizan de forma segura con tu cuenta. • Face ID / Touch ID — Autentícate al instante con Face ID o Touch ID en cada sesión.

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.
