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

professionals and enthusiasts alike can now access smaart’s real time analyzer, beautifully rendered spectrograph, and crystal clear spl meter without needing to set up a dedicated personal computer to run a desktop version of smaart*. smaart rta is capable of the same accuracy, precision, and ease of use enjoyed by live sound engineers and foh professionals across the world using the same underlying algorithms as its desktop siblings*, trusted by sound engineers to deliver accurate and actionable data in real time. *please read smaart rta creates single channel measurements only. it does not support the dual channel transfer function measurements or impulse response measurements used for system alignment and optimization, including time alignment. -- smaart rta includes -- -professional standard rta (real time analyzer) graph- the rta display helps engineers ensure an audio mix or playback balance aligns with the desired tonal response for a specific artist, performance, or specification – providing real-time analysis of frequency content and confidence that you are hearing what you are seeing. features include: fast, slow, none averaging options for graph response ballistics. 1/48, 1/24, 1/12, 1/6, 1/3, 1oct banding for precision frequency resolution. 1/3 octave x-axis frequency scale for intuitively identifying center frequencies and trends. -beatifully rendered spectrograph- the spectrograph is essential for managing and controlling feedback and identifying problem frequencies, allowing engineers to quickly visualize and address potential issues before they interfere with a performance. features include: adjustable dynamic thresholds to customize the amplitude levels represented by the spectrograph. 1000 slices in history, allowing you to ‘rewind’ the display to view events that already happened. intuitive color palette to represent amplitude level (dark to bright, quiet to loud). -clear spl display with db level meter- the spl view helps you ensure audio levels remain consistent from one show to the next or check levels for uniformity across various locations within a venue. features include: standard spl metrics of a & c weighting, with fast and slow response times. niosh and osha exposure percentages correspond with nationally accepted u.s. recommendations and occupational health and safety guidelines. large level meter display for distant viewing. the default settings for all functions in smaart rta mirror those in the desktop version of smaart v9’s real time single channel measurements. -- additional smaart rta pro features -- smaart rta pro includes the functionality of smaart rta and unlocks all settings and advanced features, including: adjustable rta graph settings (frequency scaling, bars/lines, line thickness, grid interval, etc) plot calibrated levels to view the rta graph relative to spl, rather than full scale level only. target curves (cinema x curves included, or import your own). capture and store rta data traces, allowing you to compare multiple responses across different locations or venues. average multiple stored rta data traces to view a spatially averaged frequency response. adjustable rta graph y-offsets to apply a visual db offset to live or captured data. import/export rta files (.srf) to and from smaart desktop. additional spl traffic light display for staying within venue spl limits. internal and external microphone calibration for spl. due to apple's distribution policies, free trials require a subscription selection. if you would like to try smaart rta before you buy, start with a subscription, then cancel it to avoid billing. smaart rta is $1.99p/m, $19.99p/y, or $59.99 lifetime smaart rta pro is $4.99p/m, $49.99p/y or $149 lifetime terms of use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ privacy policy: https://www.rationalacoustics.com/pages/smaart-mobile-apps-privacy-policy-terms-condtions

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.
