JustCalc

JustCalc is a scientific calculator Java applet for mobile phones. JustCalc distinguishes itself from other calculators because expressions are typed into an editable text field before being calculated. Mathematical expressions are inputted the same way you input text messages or e-mails on your mobile phone. JustCalc takes another approach than most other calculators who map actual keys to on-screen symbols to input mathematical expressions.
