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

WoodSynth is a synthesizer with 4 independent layers. Each layer is in fact a synthesizer on its own. Each layer has 3 VCO’s plus a samples or wavetable based source, coming from a file or from recording the audio track. Up to 16 voices can be set per layer. Layers can be used in parallel, assigned to a region of the keyboard or used in a sequential mode where the first note(s) on are played by layer 1 and the next note(s) by layer 2 and so on. This last mode allows to have a different sound per note played (and independent from a keyboard region). WoodSynth has a polyphonic pitch-bending touch bar which also displays notes received from a keyboard. Each layer has its own filter and envelope with ADSR per voice, a pitch shifting envelope per VCO, a delay, a basic reverb, a modulator LFO per VCO, 2 general LFO’s and a 16 steps sequencer. Key tracking can be applied on the ADSR attack and release, on the filter cutoff and on the VCO modulation. The app can be used stand-alone (device audio input and output) or as a plugin in a DAW. - IOS plugin type : AUv3 and stand-alone app.
 - Has 4 independent synthesizers, each with up to 16 voices.
 - Supports MPE and Midi V2. - Has a polyphonic touch bar with polyphonic pitch bending.
 - Velocity, channel pressure, (polyphonic) aftertouch, CC74 can be used to modulate several synth parameters.
 - VCO’s have the usual waveforms (sine, saw, square, triangle, pulse and noise) and can be modulated in various ways (FM, AM, Pulse Width, Slew rate)
 - Samples can be recorded from the audio input/track or loaded from file (sample files should be in the WoodSynth iCloud folder)
 - Wavetables can be loaded from file or converted from loaded or recorded samples.
 - Each voice has a 4-pole Moog Lowpass filter with resonance and ADSR envelope.
 - An offset can be set in the Filter cutoff for the R channel to create a stereo effect.
 - Each voice has a pitch shifting ADSR envelope which can be independently enabled for each VCO.
 - Has Key tracking for VCO pan, Filter cutoff, ADSR Envelope Attack and Release.
 - Each layer has a delay unit (which can be separately panned) and a basic reverb.
 - Each layer has a 16 steps sequencer which can run on multiple voices (poly mode).
 - Each layer can set the midi channel and range of receiving midi notes (which allows for up to 4 split keyboard regions).
 - Layers can be set in sequential mode : first note(s) played on layer1, next note(s) on layer2, etc. - Layers have an additional high-pass filter saturation and crush control.
 - Synth audio and delay can be panned independently.
 - The 2 general LFO’s can have their source from the samples or wavetables (or track input).
 - Supports Ableton Link to sync tempo and start-stop.
 - Has 4 User Control rotaries which can be freely assigned.
 - The User Controls can be controlled by a midi CC which can be set or learned.
 - Presets can be stored in iCloud Drive (makes them available on all your devices). - Supports CV out and Sequencer Midi out.

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.
