What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
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.
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.

Study for the CCM exam and run your jobs from the same app. CM Toolkit - CCM Certification is a study + work tool for construction managers preparing for the Certified Construction Manager exam — and for working CMs who want the productivity tools they actually use on a job site in the same place as their exam prep. — STUDY: PRACTICE + FULL EXAM — - 480+ multiple-choice practice questions across all 7 CMAA Standards of Practice domains: Project Management, Cost Management, Time Management, Quality Management, Contract Administration, Safety, and Professional Practice - Practice mode — study by domain at your own pace, with a written explanation after every answer - Full Exam mode — timed mock exam matched to the length and pacing pressure of the real thing - Half-Session and Domain Drill modes for shorter, more focused study blocks - Performance dashboard tracks scores over time so you can see which domains need more work before exam day — REFERENCE LIBRARY — A searchable, in-app reference covering: - CPM scheduling (forward pass, backward pass, total float, free float, critical path) - Earned Value formulas (CV, SV, CPI, SPI, EAC, ETC, TCPI, VAC) - Contract types (lump sum, GMP, CM-at-risk, design-build, IPD) - OSHA construction-safety fundamentals - AACE forensic-schedule analysis methods - CMAA Code of Professional Conduct - A working glossary of construction-management terminology — EXAM GUIDE — A plain-English walk-through of what the CCM credential is, eligibility paths, what the exam covers, scoring, and study tactics — written for working CMs who don't have time for fluff. — FIELD TOOLS (NEW in 2.1) — A working CM does more than study. Version 2.1 adds a fifth tab with on-the-job productivity features: - Projects — track active jobs by phase, budget, schedule, and risks - Calculators — Earned Value (CV/SV/CPI/SPI/EAC/TCPI), float, concrete volume + waste factor + truck-load count, liquidated damages, schedule-compression cost-per-day, common construction unit conversions - Field Logs — daily reports, decisions, RFIs, change orders, risk-register entries, and lessons learned, all organized by project — EVERYTHING WORKS OFFLINE — No login. No account. No internet required. Your projects, logs, and exam progress stay on your device. — SUPPORTS iPhone AND iPad — Optimized for both phone and tablet. Use it on the train, on a job-site trailer iPad, or at your desk. — NOT AFFILIATED. NOT ENDORSED. — CM Toolkit - CCM Certification is an independent study aid and field toolkit. It is not affiliated with, endorsed by, or sponsored by the Construction Management Association of America (CMAA). "CCM," "Certified Construction Manager," and CMAA are trademarks of the Construction Management Association of America. Using this app does not award the CCM credential — only CMAA does that, after meeting their eligibility requirements and passing their exam.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
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.
