It should work on all phones that support J2ME, like Nokia, Blackberry, Motorola, LG, Samsung, Sony Ericsson and more (specifically MIDP 2.0 and CLDC 1.1).

Current functionality:

- Up to three equations plotted simultaneously
- Three viewing modes (press enter/ok to switch mode):
  - Zoom in/out up to 8* (press up/down)
  - Pan up/down/left/right (press up/down/left/right)
  - Trace any formulae, to help draw it on paper (press left/right to trace, up/down to switch formulae)
- Scientific Calculator funciton

- Supports the following;
  - Binary operators: +, -, *, /, ^(power) and parenthesis (, )
  - Conditional operators: =, <>, <, >, <=, >=, and, or (for use in if statement)
  - Arithmetic operators: sqrt, ln, log, exp, abs, ceil, floor
  - Trig. operators: sin, cos, tan, csc, sec, cot, atan2
  - Inverse Trig. operators: asin, acos, atan, acsc, asec, acot
  - Constants: pi, e (eulers constant)
  - Conditional logic: if(condition, then, else)

Example formulae:
- 2*x^3-8*x+4 (remember to key 2*x not 2x)
- sin(x)*cos(x^2)
- if (x<2, sin(x), x^2)

Possible future functionality:
- Intersection calculation
- Polar equations
- 3D plotting
