Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.

Feature spec

Goal: Send a clear invoice after finishing a job.

  • Add a client, line items, a due date, and payment instructions.
  • Preview the total before exporting a PDF.
  • Keep an editable draft if export fails.

Screen plan

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.

Differentiate and validate

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.

App Store description

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.

Build scope

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.

Define the first version

Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.

Set boundaries

Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.

Check the hard parts

Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
