## What is TradeSkillsAI?

The AI age is reshaping work — but skilled trades are more essential than ever.
TradeSkillsAI is your complete career companion for the modern technical trades. Whether you're a student exploring options, a career-changer looking for stability, or an apprentice working toward a license, this app gives you a structured roadmap from interest to mastery.
35+ TRADES IN ONE APP
Browse traditional trades — HVAC, electrical, plumbing, automotive, mechanical/millwright, welding, and facility maintenance — alongside emerging fields like solar PV, EV charging, smart buildings, robotics, fiber optics, fire alarm, data center operations, and AI security. Plus 15 additional licensed trades from carpentry to elevator mechanic.
12 BUILT-IN FIELD CALCULATORS
Solve real problems on the jobsite:
• Ohm's Law, voltage drop (with NEC 3% check), wire ampacity, three-phase power
• HVAC load, superheat/subcool, duct CFM
• NFPA 72 fire alarm battery sizing
• Welding heat input, solar array sizing, EV charge time, pipe flow velocity
70+ CERTIFICATIONS & LICENSES
Required and optional credentials per trade — EPA 608, NATE, NCCER, IBEW, UA, ASE, AWS, NABCEP, NICET (Levels I–IV), BICSI, NFPA 70E, OSHA 10/30, IFMA, ISA CCST, FOA CFOT, EVITP, and many more — with issuers, scope, and renewal info.
EXAM PATHWAYS
A unified map of skilled trades organized into five career parts. Includes a NICET Fire Alarm Level I deep-dive: content domains, circuit types (SLC/IDC/NAC/Class A & B), cable types (FPL/FPLR/FPLP), and 30/60/90-day study plans.
BEAUTIFUL VISUALS
19 professionally rendered system diagrams (HVAC refrigeration cycle, electrical service panel, plumbing & DWV, welding setup, EV infrastructure, solar PV, fire alarm riser, smart building BAS, and more) with pinch-to-zoom. Plus interactive SwiftUI flowcharts: career path apprentice → master, certification pyramid, trade skill map, training decision tree, and an 8-week exam prep timeline.
BOOK-QUALITY REFERENCE
57-term technical glossary covering electrical, mechanical, plumbing, and HVAC vocabulary. Tools-of-the-trade lists per discipline. Code references (NEC, IPC, IMC, NFPA 72/101, ASHRAE). Vocational schools, apprenticeship programs, and online learning platforms.
BUILT FOR THE FIELD
• Works fully offline — no account, no subscription
• Optimized for iPhone and iPad
• Search across all trades, skills, certifications, and glossary
• Favorites for trades and skills
• Light & dark mode with a warm blueprint-paper theme
WHO IT'S FOR
Apprentices · Journeymen · Trade students · Career-changers · Vocational instructors · Apprenticeship coordinators · Anyone curious about hands-on, future-proof work.
AI can write, design, and predict — but it can't restore heat to a home on a cold night, rebuild an engine, or prevent contamination in a city's water supply. The future belongs to the people who build, install, and maintain the systems that keep our world running.
Educational reference only. Always verify against the current adopted codes, manufacturer instructions, and local jurisdiction requirements. Not a substitute for licensed professional advice.


## Version history (last 2 releases)

Version 1.1

• Fixed trade navigation — tapping a trade now opens its detail screen 
  reliably on all devices and iOS versions.
• Fixed Voltage Drop calculator showing incorrect results when entering 
  an AWG size not in the lookup table; it now correctly shows "—" 
  instead of a wildly wrong number.
• Fixed the 8-Week Exam Prep timeline in the Diagrams tab — week 
  arrows now appear between columns at the correct alignment.
• General stability improvements.
