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.

Snare Lab is the most complete snare drum toolkit ever built for iOS. Tune, identify, match, and dial in any sound — powered by AI. The Identify tab contains four AI modes: MATCH MY SNARE Tell the app what you want to sound like — a song, artist, or era — and tell it what drum you have. Snare Lab returns a complete guide: exact tuning targets, head recommendations chosen for your specific shell, step-by-step dampening instructions with product names and placement, snare wire recommendations, and an honest assessment of what your drum can and can't do. AI SNARE RECOMMENDER Describe the sound you're after. Get a specific snare recommendation with tuning targets, head suggestions, and a full genre-matched setup. AI PHOTO IDENTIFICATION Point your camera at any snare drum. Snare Lab identifies the brand, model, shell material, and tonal character — then loads the right setup automatically. AI AUDIO IDENTIFICATION Play a hit into the mic. The app identifies the drum by sound and populates your tuning targets. PROFESSIONAL TUNING Live lug-by-lug pitch detection with Hz readouts and note names. Supports 6, 8, 10, and 12-lug snares. Tom tuning (14 sizes) and kick drum tuning (click/attack and fundamental targets) included. HEAD RECOMMENDATIONS Every genre selection generates specific batter and resonant head recommendations for studio and live use — Remo, Evans, and Aquarian options matched to your drum and context. ONE-SHOT MIXER 25-snare professional sample library with full DSP chain: EQ, compression, reverb, delay, saturation, and transient shaping. Waveform trim with draggable handles. Export processed audio directly. SNARE CASE Save up to 10 named setups — genre, size, tuning targets, heads, and mixer state. Load any setup instantly. ACCESSORIES & DAMPENING Genre-specific recommendations for head overlays, Moongel placement, Snareweight, Revival Wires, brushes, rods, and mallets. Orchestral and marching handled separately. QUICK REFERENCE WITH READ ALOUD Full tuning reference for any drum type, readable at a glance or spoken aloud — keep your eyes on the kit while you work. Built by Trevor Lawrence Jr. for drummers who take their sound seriously.

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.
