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

【Description】 M8FX is a revolutionary, portable multi-track effects processor app designed specifically for iPhone to turn your Dirtywave M8 Tracker into a powerful, live-performing mixing rig. Connect using a single USB-C cable. M8FX hooks up directly to your M8 Tracker (running firmware version 6.0 or higher), allowing you to apply independent effects to each individual channel (CH1–CH8) using your favorite iOS AUv3 plugins with seamless real-time BPM synchronization, and route the processed audio directly back to the M8 hardware. Optimized for a permanent "Portrait (Vertical)" screen layout on iPhone and built with a hyper-responsive JUCE 8 + React/TypeScript hybrid architecture, M8FX delivers a latency-free, hardware-style experience. Perfect for both deep sound design in the studio and chaotic dub-mixing on stage. 【Key Features】 Clean Single-Cable Connection: No bulky adapters or messy wiring. A single USB-C to USB-C cable is all you need to handle 8-channel bi-directional audio routing and MIDI synchronization. Per-Channel Insert & Return (v6+ Sync): Seamlessly integrate with M8 Tracker (v6.0+) to process individual tracks through up to four AUv3 effect slots in a chain, routing the polished sound directly back into the M8 master bus. Flawless BPM Sync & Beat Effects: Live MIDI clock synchronization enables flawless integration of tempo-synced beat effects, rhythmic modulators, and time-based delays that lock perfectly with your M8's groove. Portrait Multi-Touch Mixing UI: Tailored for effortless one-handed control on iPhone with a compact 4x2 channel grid. Perform dynamic, hardware-style live dubs using responsive Mute, Solo, and toggling between Momentary/Latch send modes. 4 Macro Sliders & Dramatic Drop Controls: Maps vital AUv3 parameters to four thick macro sliders (M1–M4) for fluid hands-on control. Build massive tension by unleashing all sends simultaneously with the "ALL SEL" button, then trigger a clean drop in a split second with the pink "RST" (Reset) button. 【System Requirements】 Supported Hardware: Dirtywave M8 Tracker (Model:01 & Model:02) Required M8 Firmware: Version 6.0 or higher (for multichannel USB audio sending and return routing) Compatible Devices: USB-C equipped iPhones (iPhone 15 or later recommended) Setup Note: Please ensure "Microphone Permission" is allowed upon launch to enable USB-C audio inputs.

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.

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.
