• Questions are read aloud with a voice in your chosen language.
• Help is now available in German, French, Italian, Polish and Spanish, and matches the current calculators.
• All question diagrams are redrawn: sharper, and in your language.
• Corrections: P-T chart pressures, R-134a gauge temperatures, cascade system flow, refrigerant safety classes and the TEV explanation.
• Choose your language when you first open the app; changing language during a quiz now asks first.
• Equipment and experience log PDFs show dates in your language's format.
