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.

Run every cardiac arrest with confidence. Code Runner Pro is the complete CPR timer, ACLS code log, and resuscitation documentation tool for healthcare providers — built for real code blues in real hospitals, with full Apple Watch support for when every second counts. From the first compressions to ROSC, Code Runner Pro tracks your code, your rhythms, your medications, and your shocks in real time — then exports a clean PDF report for charting, debriefs, and review. Trusted by doctors, nurses, paramedics, and first responders in more than 24 countries. ■ FOUR SIMULTANEOUS CODE TIMERS Track Code Time, CPR cycles, Shock intervals, and Epinephrine dosing — all at once, all visible, all synchronized. No other code blue app gives you this level of real-time timing control. ■ REAL-TIME CODE BLUE LOG Document compressions, rhythms, pulse checks, ACLS medications, defibrillation, and events the moment they happen. Every entry is timestamped automatically for a clean, defensible resuscitation record. ■ QUICK MEDS — LIFE-SAVING ACCESS Customize your own ACLS medications — epinephrine, amiodarone, atropine, bicarb, calcium, magnesium, and more — and place them right on the home screen. Tap once to document. Color-code, reorder, and build the cardiac arrest kit that matches your practice. ■ REDESIGNED FULL CODE LOG A beautiful timeline view of the entire resuscitation event — from initial rhythm to ROSC or NO ROSC. Review every compression cycle, every medication, every shock in one clean chronological report. ■ BUILT-IN CPR METRONOME Deliver high-quality compressions at 100–120 BPM with an adjustable, clinically accurate CPR metronome. Available on iPhone and Apple Watch, with multiple sound options. Plays even when your phone is silent. ■ APPLE WATCH — RUN CODES FROM YOUR WRIST Start CPR, toggle timers, log epinephrine, document shocks, and track rhythms directly from Apple Watch. Perfect for bedside providers whose hands are full or who need discreet documentation during a code. ■ PEDIATRIC CODES SUPPORT Switch to the pediatric list for age-appropriate ACLS medications, rhythms, and events. PALS-ready for NICU, PICU, and pediatric emergency settings. ■ ONE-TAP PDF EXPORT Generate a polished, professional PDF of the entire code — timeline, medications, rhythms, shocks, and outcomes — ready to hand off to the attending, attach to the chart, or submit for code review and quality assurance. ■ CUSTOMIZE YOUR WORKFLOW Adjust metronome sounds, alert styles, timer visibility, medication order, and rhythm options. Code Runner Pro adapts to how your team runs codes. ■ BUILT FOR REAL CLINICAL ENVIRONMENTS Used daily in: - Emergency Departments (ED) - Intensive Care Units (ICU, CCU, MICU, SICU, PICU, NICU) - Medical and Surgical Wards - Rapid Response Teams - Code Teams - Prehospital and EMS - Paramedic and first responder settings ■ WHY CODE RUNNER PRO - Four simultaneous timers (most code blue apps give you one or two) - Full Apple Watch support with dedicated shock and epinephrine controls - Pediatric-ready medication and rhythm lists - Clean, exportable PDF code log for documentation and chart closing - Designed by and for clinicians who actually run codes - Trusted in more than 24 countries worldwide Run the code. Log the code. Save the life. Code Runner Pro handles the timing and tracking so you can focus on the patient. Have feedback or feature requests? Visit coderunnerpro.app

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.
