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

Grand Finale has been given some much needed love and attention resulting in a major face lift and a some extra horse power under the hood - resulting in Grand Finale 2! The iOS app now has custom interfaces for iPhone and iPad, and it works both as standalone and as an AUv3 plugin. Grand Finale 2 is a multi effect audio processing application designed for finalizing complete mixes, stems, voice overs, buses and/or individual audio tracks. The plug-in offers several modules in a pre-routed configuration. Each module has parameters to alter, and most modules offer a set of algorithms to select. These features come together to make Grand Finale a powerful tool for quickly finalizing a track, bus or mix. Usage: Import audio files, or extract from a video in the camera roll. Audio can also be imported by using the “Open In..” option in any other app that can export audio. Use the playback controls to start and stop playing, and alter the module knobs/options to change how the audio is processed. When satisfied with the result, tap Export to render and save the finalized audio file. Included DSP Modules: Main bus processing • High Pass filter • Compressor • Multiband Compressor • MS Stereo Tool • Equalizer • Limiter Additive/parallel processing • Compressor • Distortion Other features: • Accurate RMS and LUFS metering (tap the meters to swap) • 37 professionally made factory presets. • Load / Save custom user presets • Project manager (load / save full state including audio file data) • User manual bundled inside app. • Parallel processing is phase linear. • Exports to WAV/AIFF/AAC at 16, 24 or 32 bits (sample rate is preserved) Listening examples (pre/post) available here: https://soundcloud.com/klevgrandproducts/sets/grand-finale-audio-examples Said about Grand Finale: “The magic behind this plugin is the compressor on the bottom portion, the stereo processor and the incredible EQ section. The bass and treble EQ (in default mode) is the best I've heard by far in a plugin.“ - Robbie Soukiasyan (Skrillex, Tiesto, Usher and more..) “...and Grand Finale is a genuinely impressive processor for not only the master output, but also mix busses and even individual tracks…” - Computer Music Magazine (CM254) “Overall, we are impressed by Grand Finale. The plug-in is well thought out and has a very modern, sleek user interface that doesn’t compromise on intuitiveness, metering, or other relevant information and features. Such things help with standing out in the crowded mastering/finalization plug-ins market.” - Gearnews.com

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.
