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.

Kompute gives you 10 precision tools for studio math, all in one app. TAP TEMPO + METRONOME Tap to detect BPM with decimal precision. Built-in metronome. Round to nearest whole BPM or keep the exact reading. DELAY TIME TABLE Enter a BPM and see tempo-synced delay times for 21 note divisions. Normal, dotted, and triplet values in both milliseconds and Hz. NOTE TO FREQUENCY Convert any musical note to Hz. Supports 100+ temperaments beyond standard equal temperament. Adjustable concert pitch. Audio preview per note. FREQUENCY TO NOTE Enter a frequency, find the closest musical note with cents deviation. Identify the pitch of any sound. SAMPLE LENGTH CONVERTER Bidirectional conversion between samples, milliseconds, seconds, bars, and beats. Edit any field, all others recalculate. TEMPO CHANGE CALCULATOR Calculate time-stretch ratio and transposition when changing from one tempo to another. Shows stretch percentage, tempo delta, and semitone shift. TIMECODE CALCULATOR Full timecode arithmetic for video and film. Add, subtract, and multiply timecodes. Supports 10 FPS formats including 23.976, 29.97 drop frame, and 59.94. REVERB PRE-DELAY Calculate tempo-synced pre-delay values. Small, medium, large, and hall presets. Keep your reverb rhythmically aligned. COMPRESSOR SYNC Tempo-synced attack and release times.

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.
