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.

Konnakol is a practice app for the South Indian rhythmic solfège tradition — reciting patterns of syllables (sollu) over a tala (rhythmic cycle), the foundation of Carnatic rhythm. LESSONS 22 guided lessons build from "what is a tala" to genuine advanced cross-rhythms: every gati (tisra, misra, sankirna...), talas beyond the basic cycle, "second speed" density, and a preview of the tihai cadence — including lessons that let you hear a phrase drift across a steady beat instead of just subdividing it faster. PRACTICE A configurable tala/nadai metronome with independent phrase length, so you can recite a pattern that resets every beat, or one that runs continuously across the beat grid for real polyrhythmic practice. EXPLORER Build your own jati combinations and audition them in a loop — a sandbox for exploring korvai-style phrases. REAL VOICE, REAL TABLA, REAL DRONE Syllables are recited with real recorded voice samples, not synthesized speech. Switch to a tabla voice for a different color, or layer in an ambient tambura drone — each with its own volume control. HAND POSITIONS Watch the tala's clap, wave, and finger-count hand positions animate in sync with the beat, so you can learn the physical gestures alongside the syllables. Works entirely offline. No account, no ads, no data collection, no permissions requested.

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.
