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

Motion Sickness Relief delivers a science-backed 100 Hz tone that helps alleviate motion sickness symptoms through innovative sound therapy technology. Based on breakthrough research from Nagoya University, this specific 100 Hz pure tone has been shown to effectively reduce motion sickness by stimulating the otolithic organs in the inner ear, which are responsible for detecting linear acceleration and gravity. HOW IT WORKS: • The 100 Hz tone helps improve balance and spatial orientation • Just one minute of exposure can reduce nausea and dizziness • Research shows effects can last for up to two hours • Safe sound pressure levels similar to everyday environmental noise KEY FEATURES: • Simple, easy-to-use interface • Three convenient modes: 1-minute, 5-minute, or continuous play • Adjustable volume control • Works best with headphones for optimal tone delivery • Start using at the first sign of motion sickness symptoms EVIDENCE-BASED SOLUTION: Clinical research has demonstrated significant symptom reduction in human trials involving driving simulators, swings, and real cars. Scientific analysis showed improved balance and positive modulation of the autonomic nervous system, which is often dysregulated during motion sickness. PERFECT FOR: • Car travel • Boat trips • Air travel • Virtual reality experiences • Amusement park rides • Reading while in motion • Anyone susceptible to motion sickness Get relief from motion sickness symptoms with this simple, science-based solution - no medications, no side effects, just a pure 100 Hz tone that works with your body's natural balance systems. Purpose and Working of App Description: Motion Sickness Relief utilizes sound therapy principles to alleviate motion sickness symptoms. The app generates a precise 100 Hz tone that stimulates the otolithic organs in the inner ear, which helps the brain better reconcile conflicting sensory information that causes motion sickness. The app works by allowing users to play this specific frequency through their device's speakers or headphones (recommended for best results). Users can select from three duration options: a quick 1-minute session, a standard 5-minute session, or a continuous mode for ongoing relief during longer journeys. Scientific research from Nagoya University has demonstrated that this 100 Hz tone can reduce objective symptoms of motion sickness and improve balance, with effects lasting up to two hours after just five minutes of exposure. The sound uses safe pressure levels within the range of normal environmental sounds. The primary purpose is to provide a medication-free, side-effect-free alternative for people who experience motion sickness while traveling, using virtual reality, or in other motion-intensive scenarios. The app interface is deliberately simple to allow easy use during the onset of motion sickness symptoms.

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.
