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.

Core Features Interactive Interval Training Develop sensitivity to pitch relationships by exploring intervals tuned using just intonation. • Hear intervals begin perfectly aligned • Adjust pitch in real time to hear beats appear and disappear • Tune intervals by ear using guided listening exercises • Practice intervals across multiple keys and registers Chord Tuning and Harmonic Awareness Understand how scale degrees shape harmony by exploring chords built from pure tuning relationships. • Major, minor, diminished, and augmented triads • Seventh chords including dominant, major, minor, half-diminished, and fully diminished • Isolate chord tones to hear how each pitch affects resonance • Adjust individual notes to hear chords stabilize or destabilize Challenge Mode Strengthen listening accuracy through progressive ear-training exercises. • Tune intervals by ear with adjustable difficulty levels • Customize time limits and precision targets • Unlock intervals through guided progression • Track improvement and share results with teachers or directors Lab Mode Experiment freely with pitch relationships and harmonic structure. • Build custom intervals, chords, or harmonic textures • Assign independent tuning values to each pitch • Explore consonance, dissonance, and overtone interaction Designed for Real Musical Environments In rehearsals and performances, musicians rarely hear themselves in isolation. Beat-Less Tuning removes ensemble noise and allows you to focus on deliberate listening, helping you build reliable tuning instincts that translate directly into real musical situations. This app is ideal for: • Band and orchestra students • Choir and vocal ensemble singers (especially Straight-Tone singing) • Drum corps and marching musicians • Barbershop and a cappella performers • Music educators and ensemble directors Why Just Intonation? Most modern instruments use equal temperament, which balances pitch across all keys but slightly compromises many intervals. Beat-Less Tuning introduces just intonation, where intervals follow natural harmonic ratios that create clarity, depth, and resonance. The listening skills developed in this app strengthen tuning awareness in any musical tuning system. Built by Musicians and Educators Beat-Less Tuning was created by Grammy Finalist and Recording Academy Music Educator of the Year Jeremy Bradstreet, in collaboration with software developer Noirit Ghosh Choudhuri. Together they combined decades of teaching experience and advanced software design to create a powerful and intuitive listening tool for musicians at every level. Train your ears. Build your sound. Hear music more clearly.

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.
