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

KOMBINAT4 is Audio Damage's fourth-generation flagship distortion. Take any sound, split it into up to eight frequency bands, and assign one of 38 distortion engines to each band. Or flip to Serial mode and chain those eight engines end-to-end for stacked, cascading mayhem. THIRTY-EIGHT DISTORTION ENGINES The complete roster from Kombinat Tri returns: Fuzz, Saturate, Distort, Clip, Warp, Degrade, Ring Mod, X Noise, Octaver, Wavy, Rectify, Tube Clip, and the famously unhinged Nerd Rage. Joining them is the entire engine set from our Grind distortion: Tanh, Asym Tanh, Overdrive, Polynomial, Linear Distort, Sine Drive, Var Hard Clip, Gloubi Boulga, MXR, Soft Clip, and Cubic NLD. Plus thirteen brand-new algorithms built specifically for Kombinat4: Wavefold, Chebyshev, Bitwise, Slew Limit, Comparator, Diode Clip, Feedback FM, Fractal, Dropout, Shapeshift, Phase Distortion, Stutter, and Erosion. Every engine has up to three custom-labeled controls plus per-band gain and solo. Pick a different engine for each band and design distortion tones that simply weren't available before. EIGHT BANDS, TWO MODES In Multiband mode, the input is split by Linkwitz-Riley crossovers into up to eight parallel bands. Each band gets its own engine and gain stage, and everything recombines at the output. Drop to two bands for classic low/high splits, push to eight for full-spectrum surgical distortion design, and solo any band to dial it in cleanly. In Serial mode, those same eight slots become a chain — every engine processes the full-bandwidth signal in turn, for layered drive structures impossible to achieve with a single algorithm. OUTPUT SECTION A dedicated output filter with twelve types: 2-pole and 4-pole low-pass, high-pass, and band-pass shapes, a notch, three OTA-style filters, a 914-style ladder bandpass, our Filterpod, and bypass. Built-in Rough Rider compressor at the output with sidechain HPF and external sidechain input. Global feedback path with attack and decay envelope for self-oscillating screams and slow-blooming sustain. Optional AGC for level-matched A/B comparisons across heavy distortion settings. DC blocker. 2x and 4x oversampling for clean high-frequency content. PRESETS AND WORKFLOW Factory preset library covering subtle saturation, mix-bus enhancement, mid-range fattening, lead guitar tones, low-end mangling, full-on industrial destruction, and everything in between. Folder-based user preset browser with favorites and import/export of single presets or full folders as ZIP. XML preset compatibility with the desktop edition — your iOS presets work in your DAW and vice versa. AUv3 plugin for iOS hosts including GarageBand, Logic Pro for iPad, AUM, Cubasis, Loopy Pro, Audiobus, drambo, BeatMaker 3, and others. Standalone app included. Tooltips on every control. Animated band display with realtime spectrum overlay. No DRM, no account, no online activation.

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.
