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.

You're standing in front of a property with your client. The deal looks right. Do you say "let me get back to you tomorrow" — or do you run the numbers in 60 seconds and close it on the spot? EstiMate CRE puts 10 professional-grade commercial real estate calculators in your pocket. No laptop. No spreadsheet. No re-typing numbers between apps. THE SMART SUGGESTION ENGINE This is what separates EstiMate from every other calculator app. Open Cap Rate? It already knows your NOI from the previous screen. Checking DSCR? It pulls your NOI and converts the loan payment automatically. Running Cash-on-Cash? It suggests your down payment from LTV without you touching the keyboard. Stop re-entering the same numbers. Start closing faster. 10 PROFESSIONAL-GRADE CALCULATORS - NOI — Full income and expense breakdown with EGI, total OpEx, OER, and bottom-line NOI - Cap Rate Tri-Solve — Enter any 2 of NOI, Cap Rate, or Value and solve for the third - DSCR — Live pulse ratings (Strong, Adequate, Marginal) so you know what the bank will say before you call - GRM Tri-Solve — Find GRM, value, or required rent and compare rental yields instantly - LTV & Debt-to-Equity — Find LTV, max loan amount, or down payment for lender meetings - True Loan Payment — Full P&I amortization with expandable PITI breakdown including taxes, insurance, CAM, and reserves - Cash-on-Cash Return — Itemize down payment, rehab, fees, and reserves for your true return on injected equity - Land Price Converter — Convert price per square foot to price per acre on the fly - 1031 Exchange Tracker — Visual countdown rings for 45-day ID and 180-day closing deadlines - Lease vs. Buy — 10-year analysis with year-by-year crossover visibility showing exactly when buying overtakes leasing LIVING DEAL FILES Every calculation saves to a deal file. Everything groups logically by property. Tweak one number, re-save, and iterate faster than anyone else. Encrypted iCloud sync keeps everything accessible across all your devices. BUILT FOR THE FIELD - Commercial Brokers — Run deal analysis during showings. Give clients answers on the spot. - Investors — Compare properties instantly. Track every metric for every acquisition. - Lenders & Underwriters — Run fast DSCR and LTV stress tests before heavy underwriting. - Developers — Structure loan scenarios and decode land pricing for high-stakes opportunities. Stop guessing. Start closing.

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.
