• Mechatronics
• Software
• Energy

Voltlingo is free for a while. Every unit and the Symbol Library are open. Sign in with Google to save progress and unlock Unit 2+. Paid membership will return later.

What you get
• Unit-based lessons with engineering terms, definitions, and examples
• Symbol quizzes with schematic-style graphics
• Hearts, XP, streaks, and weak-word review
• Leaderboards and daily goals

Built for engineers, technicians, and engineering students who need workplace English.
Technical English for engineers. All units are free for a while.
