Perfect lite calculator

Best, free little calc I could find. Your can set a custom plain bg (shoot a table top photo or something) for ease of seeing numbers and the paper tape feature (you can see the string of numbers and calcs youre using) is super helpful. You can even email that tape to others. Perfect for lightweight calculations.
