Alt1 Calculator is a minimalistic but full-featured scientific calculator for your desktop.

You can perform simple or complex computations without the need for an overly complex UI as all its functions are straight through your keyboard. When not being used, the calculator resides in the system tray for simple and quick deployment. Just click the icon or hit the convenient hotkey (Alt + 1).

Calculations performed by Alt1 Calculator are in real-time; there is no equal button. All your equations and answers are stored for later use so you can refer or edit them at any time. Additionally, when editing previous equations, they will instantly update any subsequent dependent answers. It is easy to use and it also includes a keyboard map (in the help section) with all calculator key positions listed for quick reference.
