Full description

Engineer's Companion brings practical calculators and technical references together for engineering and trade work. Explore tools for electrical work, carpentry, aviation, welding, and more. Keep frequently used tools close with My Calculators. Save favorites from across the app and arrange them in the order that works for you. Customize your home screen and display preferences on your device. Optional feature packs let you add tools as you need them. Download selected reference documents for later use. Internet access is needed for downloads, external references, and sending feedback. Report a problem or suggest a feature using the in-app feedback forms. Check each tool's assumptions and verify results against applicable standards, manufacturer instructions, and professional requirements for your work. Unit Converter and Engineering Calculator are free. Other trade calculators and reference tools require Pro. Choose either a one-time permanent purchase or an optional monthly subscription; both unlock the same Pro tools. Monthly Pro renews automatically until canceled in Google Play. You can manage or cancel it there, and access continues until the current paid period ends. A subscription is not required to use the free tools. Current localized prices are shown by Google Play before purchase. Pro purchases restore through the same Google Play account. Internet is required to purchase, restore, and periodically verify ownership. After verification, downloaded Pro tools work offline for up to seven days. Pro also includes home-screen calculator widgets for a selected calculator or saved conversion. Engineers Companion is actively developed and regularly improved. Usage analytics is optional, requires your permission, and is never required to purchase or use Pro.

What's new

Monthly Pro is available alongside the permanent Pro purchase. Both unlock the same tools. Unit Converter and Engineering Calculator remain free.
