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

• Let the musical muses of Piano Motifs inspire your device to generate some original and beautiful motifs (short melodies). • Selected as the Favorite MIDI Generator App two years in a row by the iOS Music Production community! • Check out the music that Piano Motifs can generate at: https://soundcloud.com/azul-3d • For Piano Motifs demos and tutorials: https://www.youtube.com/@azul3dapps • Create original, catchy and inspiring MIDI loops at the touch of a button. • No musical knowledge or skill is necessary to create completely new and original music. Piano Motifs is the simplest way to generate your own music. • There are no preset melodies. Melodies are generated algorithmically. The melodic possibilities are endless. • Set the music tempo or select the key, scale, time signature, octave range, number of bars, melody constraints, melody note frequency and accompaniment style for your motif. • Option to generate Swing rhythm for the melody, either Shuffle or Hard Swing. • Program your own chord progressions and let Piano Motifs generate an accompaniment and melody for them. • Generation of a 3rd track with the option of it being a sustained chord per bar, sustained chord per multiple bars or a drone tone. Ideal for strings, choirs or pads. • Arrange your motifs to create longer musical pieces. • Choose from 24 different kinds of accompaniment styles. • Define your arpeggio accompaniments. • Choose from 13 different kinds of melody constraints. • Major, Minor, Lydian, Mixolydian, Dorian, Phrygian, Harmonic Minor and Phrygian Dominant scales supported. • Loop your motifs • Save your motifs as MIDI files so you can edit them or add more instrumentation to them on your favorite Digital Audio Workstation (DAW). • Many options when exporting a MIDI file or one MIDI file per track. When exporting a MIDI file, export with a third MIDI track with a sustained chord per bar, sustained chord per multiple bars or a drone tone (Ideal for synth pads, strings or chorus). • Share audio or MIDI through iMessages, e-mail, Whatsapp or AirDrop. Save audio, MIDI or .motif file to your device's file system. • AUv3 MIDI Plug-In In-App Purchase: Incorporate Piano Motifs seemlessly in your workflow by instantiating it once or multiple times in an app that can host AUv3 MIDI Plug-Ins, for example: AUM, AudioBus 3, ApeMatrix, Drambo or EG Nodes. Please note that Piano Motifs as an AUv3 MIDI Plug-In will not play any sound by itself, it generates MIDI that can be routed to other apps and effects instantiated in a host. IMPORTANT: GarageBand does not support MIDI only Plug-ins, so the AUv3 will not work in GarageBand. • AUv3 MIDI Plug-In features include: - Ability to play Piano Motifs in sync and out of sync with the host. - State saving functionality. - Independent programmable MIDI channels for melody, accompaniment, optional third track, and optional melody harmony track. - Interactive octave shifting for melody and accompaniment. - Controllable Melody and Accompaniment Velocity parameters. - Start Delay and BPM multiple with respect to the Host in Sync mode. • MIDI Out In-App Purchase:  Play the music generated by Piano Motifs on your favorite synthesizer, DAW, a connect/route/mix app like AUM, or any app that has Virtual MIDI Destination (MIDI In) capabilities. IMPORTANT: Before purchasing please be aware that Piano Motifs DOES NOT OFFER Ableton Link functionality. • MIDI Out In-App Purchase features include:  - Programmable delay for the start of a motif - Independent programmable MIDI channels for melody, accompaniment and an optional third track - MIDI Out settings are saved between Piano Motifs sessions • Piano Motifs chooses a music key from many different scales and an accompaniment from a varied set of accompaniments. Piano Motifs then uses its musical theory algorithms to overlay a melody in the chosen key and accompaniment. Piano Motifs are short, they go from around 16 seconds to around 30 seconds.

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.
