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

TTAP for iOS is an AUv3 delay effect inspired both by adventures with analog tape and by otherworldly textural effects only possible in the digital world. Whether you’re looking for bread-and-butter delay sounds, subtle enhancements, or evolving experimental echoes, TTAP fits what you need. *** Please note: TTAP is an Audio Unit extension (AUv3) – it only works in an AUv3 host app like Garageband, AUM, Cubasis, Modstep, Beatmaker 3, etc... *** HOW IT WORKS / DESCRIPTION TTAP is a delay with two buffers. Each buffer features extensive controls for shaping the envelope of the delay sound, with another control set for glitchy pre-feedback repeats and warm pitch-bends. Inspired by both the classic sounds of tape delays and by experiments in editing and splicing tape, TTAP features a dedicated Section control for determining the maximum length of time of the second buffer. Section also acts as a virtual LFO control, affecting a number of modulation parameters. Both the Delay Time and Section controls in TTAP can either be synced to your DAW, or run free, providing up to 3.0 seconds of time for each. Try changing the speed while TTAP is running with high feedback for the expanding/contracting doppler sound familiar to any dub lover (or automate and randomize the process using the Bend control). — In The Fade Fade easily between two delay buffers, or jump to using one buffer exclusively with the click of a button. Glitch and Chance In addition to the familiar feedback control, TTAP includes controls for randomized Repeats (synced to the Section time) for a glitchier sound. In addition, each of the buffers features a dedicated Reverse switch. Intuitive Display In addition to control positions, the animations in TTAP give you essential information such as the mix between buffers, amount of feedback, time gap between buffers, and the envelope for each buffer. Go By Feel As part of encouraging more musical and creative applications of WOV, in addition to using symbols for controls, the controls in WOV do not have individual readouts. We encourage you to let your ears determine the right knob positions whenever you can! If you’d like a precise readout, however, you can see/edit it by clicking on any parameter and looking in the upper-right corner of WOV. Icons By default, all labels are graphical – for text labels, click the symbols/text label switch in the lower-right had corner.

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.
