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

Create music with Loopy HD by layering looped recordings of singing, beatboxing, or playing an instrument with a savvy, sophisticated, tactile looper that totally reinvents the formula. As seen on The Tonight Show Starring Jimmy Fallon. https://loopyapp.com -- “This is the best loop station on the iPhone” -- Dub FX (dubfx.net) -- “I pretty much own every mobile looper out there and Loopy is HANDS DOWN the best. Super simple interface with powerful features.” -- J. Alan Meier -- “If you want a recording app that will get out of the way and just let you be creative, you just found it.” -- Dave Merson-Hess, indie film composer -- “Loopy 2 is by far the best looper for the iPhone we’ve seen to date” -- iOS Recording Compatible with the Audiobus app: Record and loop live audio directly from other Audiobus-compatible apps! While other music creation apps tend to be either powerful but difficult to learn, or easy to use but limited in features, Loopy doesn't compromise. Loopy offers a sleek, expressive, instantly understandable interface that beginners can start using effectively straight away. It's fun, right from the start. More advanced users, however, will not be disappointed by Loopy's rich feature set, with extra features many other loopers just don't have. Plus, a sophisticated interactive tutorial system lets users discover Loopy's more advanced features at their own pace. RECORD & LAYER - Six, nine, or twelve beautifully rendered circular loops, with simple yet powerful controls. - Count-in, count-out and record chaining lets you keep your hands free to play an instrument. - MIDI control, to control Loopy via foot pedal or other controller. - Overdub, to build beautiful, complex soundscapes from many layers. - Support for tracks of any multiple or fraction of a beat, for flexible and expressive looping. - Sophisticated audio or visual metronome to keep you in time - no matter what time signature you choose. - Perfectly synchronized, low latency audio engine. - Robust MIDI clock receive and send, and support for Ableton Link. IMPORT & CONSTRUCT - Import loops from your computer via iTunes, with support for AIFF, WAV, MP3, M4A, CAF and more. - Bring in audio from many other audio apps with integrated audio copy and paste. - Imported loops are automatically fit to your beat, no matter what tempo. MANIPULATE & TWEAK - Full stereo audio, with pan controls for each track to create custom stereoscapes. - Fix up timing by twisting tracks around to line up the beat, or make funky sound effects with dynamic time shifting. - Drag a track onto another track to merge tracks, and clear up a space. - Live, dynamic tempo adjustment to speed up or slow down your creations, without altering the pitch. - MIDI clock sync, to play in time with other MIDI-capable devices or apps. PERFORM & SHARE - Record whole performances with in-app session recording facilities. - Upload performances or single loops straight to SoundCloud, and post to Twitter or Facebook. - Email audio clips. - Share audio with many other audio apps with audio copy and paste. - Transfer loops or performances to your computer via iTunes. ----- Loopy is developed by one guy who loves making great apps, and who is dedicated to responsive development and support.

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.
