This product is awesome. I work daily with an ERP software that constantly has me moving from mouse to keyboard for field interactions or clicking specific menu icons. I bought a nine button programmable mouse to handle the pesky keystrokes. While this mouse may work with gaming software, the ERP software doesn't. Enter your Key Remapper. With it I am able to program all the extra mouse buttons to perform the keyboard and menu actions I find so inconvenient. It has definitely made life easier at work. Thank you!
Now, do you offer a wife remapper? 🙂

Multi-Screen Voice Calculator is a calculator for everyday use for Android devices, that lets you:

  • Instantly enter numbers and mathematical expressions using an ergonomic on-screen keyboard and voice input. Just press the mic button and speak the expression (for example, 74 point 5 times 4 plus 37 = 74.5 × 4 + 37 = 335): it will appear on screen and the result will be calculated immediately!

  • Make two or more calculations simultaneously. To do this, you can switch editing screens with a horizontal swipe along the top edge. You can give names to screens by tapping the screen number.

  • Quickly copy the result to the clipboard simply by tapping it. There is a special button for pasting from the clipboard (📋).

  • All calculations are recorded in the calculations history, from where you can insert the expression and result into the editor. These records can be instantly deleted with a horizontal swipe. Any record from the history can be tagged with text by tapping the date or time.

  • Execute mathematical operations with incredibly large numbers and expressions.

  • Raise to the n-th power or extract the root of the n-th power (for example: 5 cubed = 5^3 = 125; the cube root of 27 = 3√27 = 3).

  • Percentage calculations (for example: 200 + 10% = 220; 10 % 200 = 20).

  • Convenient, user-friendly settings that can be opened by swiping from the left edge of the screen or using a menu button. The settings include: vibrate on click, full-screen mode, keep screen on, and other options.

  • The result is always displayed naturally, without incomprehensible E's, dashes, and numbers.

  • Easily work with many memory cells, and easily switch between them. You can set a name for each cell, letting you intuitively use the memory for a specific field of activity.

  • Quickly switch themes.
