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

Aether Synth now includes AUv3 instrument support, letting you load Aether directly inside compatible iOS hosts like GarageBand, Logic Pro for iPad, and other AUv3-supported music apps. Use Aether Synth as a standalone iOS synthesizer and music creation workstation, or open it inside your favorite DAW as an Audio Unit instrument for recording, sequencing, layering, and producing with Aether sounds in your projects. Aether Synth is built for fast inspiration, deep sound design, and expressive performance. Whether you are just starting out or already producing music, Aether Synth gives you a creative space to build sounds, play instruments, sequence ideas, shape presets, sample audio, and experiment with immersive motion. Start with ready-to-play presets, then go deeper with advanced synth controls, dual-layer sound design, rhythmic motion, melodic sequencing, drums, effects, multitrack creation, and AUv3 host integration. Made for beginners and advanced creators Aether Synth is designed to feel immediate when you want quick results, but deep when you want to sculpt every detail. Load a preset, play the keyboard, trigger sequences, layer sounds, build a full idea from scratch, or use Aether as an AUv3 instrument inside your host. Key features include: • AUv3 instrument support for compatible iOS music hosts • Standalone synth and music creation workstation • Professional synthesizer engine with rich, expressive sound • Dual preset layering for bigger, wider, more complex patches • Built-in keyboard performance view • Melodic sequencer for creating patterns and riffs • Drum sequencer for beat creation • Sampler tools for working with audio ideas • Multitrack audio workspace for arranging and bouncing ideas • Arpeggiator and motion controls for rhythmic energy • Host-synced motion, ARP, and SEQ-style sounds in AUv3 hosts • LFO-based movement for evolving sounds • Spatial audio-inspired motion and immersive preset design in the standalone app • Reverb, delay, chorus, drive, filter, and tone-shaping tools • Preset browser for quickly finding usable sounds • Random Sound and Random Motion tools for fast inspiration • Themeable interface with modern visual styles • Designed for touch, live play, mobile creativity, and DAW workflows Create sounds that move Aether Synth is built around movement and expression. Use evolving presets, rhythmic modulation, layered textures, and spatial motion controls to create sounds that feel alive. Use Aether inside your DAW With AUv3 instrument support, Aether Synth can now be used inside compatible iOS hosts. Load it as an instrument, play it with the host keyboard, record MIDI, sequence parts, layer multiple instances, and use Aether sounds directly in your productions. Build musical ideas fast Use the melodic sequencer, drum sequencer, keyboard view, sampler, and multitrack page to turn a sound into a full sketch. Create loops, experiment with patterns, layer parts, and bounce your ideas. For sound designers Go beyond simple preset playing. Shape tone, motion, stereo width, effects, envelopes, filters, layers, and modulation to design custom patches with character. For producers Quickly create basses, pads, leads, bells, plucks, rhythmic textures, drums, loops, and atmospheric layers directly on your device or inside your AUv3 host. For beginners You do not need to understand every control right away. Start with presets, use the keyboard, try the sequencers, open Aether in GarageBand or Logic Pro for iPad, and explore the sound by turning simple controls. Aether Synth is built for creators who want a serious synth that still feels fun, visual, and immediate. Create. Play. Sequence. Sample. Layer. Move sound. Use Aether as an AUv3 instrument.

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.
