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

Built for Fieldwork. Not Paperwork. Your sampling day is long enough. Stop taking the same paperwork home with you. Interactive COC puts your Chain of Custody workflow in your hands, so you can document samples, create a professional COC and send it to the laboratory while you are still on the job. Less retyping in the field. Less paperwork waiting at the office. MAKE THE NEXT COC EASIER THAN THE LAST. You already entered your name, your company, the project and laboratory information. Put it to work again. Reuse saved details or duplicate a previous COC for the next sampling day, then update what changed. Sample numbers increment as you add or duplicate samples. GIVE YOUR LAB INFORMATION IT CAN READ. Send a clean, professional PDF that takes handwriting out of the equation. Your laboratory gets a readable submission, and you get an emailed copy for your project files without scanning a paper form. CSV and XML files give you the sample data as well, with Submission IDs and QR codes to help identify your records. FIND THE TESTING YOU NEED AND KEEP MOVING. Search laboratories by name, city, state, country, analysis category or type of analysis. Spend less time scrolling through lists to find the lab and testing your job needs. Separate Performing Office details and email keep the individual office handling the work identified. TAKE REPETITIVE TASKS OFF YOUR HANDS. Scan existing sample barcodes and QR codes instead of typing their numbers. Let the app calculate elapsed sampling time and air volume from your dates, times and flow rates, even when sampling crosses midnight. Capture photos, GPS locations and signatures while you are there. WORK IN THE LANGUAGE YOU PREFER. Use Interactive COC in English and eight other languages. The laboratory receives the COC in English or the other languages, so your field team can work in its preferred language while keeping submissions consistent. GET MORE ROOM ON YOUR IPAD. Two interactive panels in landscape keep more of your workflow in view and let you work within either panel. Use your iPhone in the field or the familiar iPhone-sized app layout on a supported Apple laptop. USE ONE FAMILIAR WORKFLOW ACROSS YOUR JOBS. Create COCs for Asbestos Air, Bulk Materials, Single-Sample Air, Multi-Bulk, Police and Forensic Evidence, and now Multi-Air Analysis. Wastewater, Methamphetamine, Lead, Mold, Heavy Metals, Cannabis, Wine and Beverage testing options are available through laboratories listed in the app. Built by a consultant with more than 40 years of environmental consulting, industrial hygiene and field sampling experience, Interactive COC reflects the small details that make a difference over a full day of sampling. PUT IT TO WORK ON YOUR NEXT JOB. Your first 3 COCs are free. Create a submission with your own project, your own samples and your chosen laboratory. See how much repeated work you can leave behind. Then choose individual submissions, bundles, an unlimited individual plan or a company plan to fit the way you work. Download Interactive COC and get your next COC off your to-do list.

Opportunities

AI-GENERATED OPPORTUNITY HYPOTHESES

These are generated suggestions, not verified review quotations. Check current App Store reviews and speak with users before treating a possible gap as a requirement.

Hypothesis 1

Include notifications and feedback mechanisms after COC creation.

Assumption to check: Limited user feedback and interaction options

Validate with people who use this workflow before building.

Hypothesis 2

Implement a guided onboarding process.

Assumption to check: Difficult navigation for new users

Validate with people who use this workflow before building.

Hypothesis 3

Provide insights and analytics on COC usage.

Assumption to check: Lack of analytics and reporting features

Validate with people who use this workflow before building.

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.
