An iPad app that solves handwritten mathematical expressions

GridPaper understands operators, fractions, brackets, indices and constants like pi and e. It can also solve equations. To solve for an unknown use x in your expression, or just leave a gap.

Use one finger to draw on the grid. GridPaper works as you draw, writing it’s analysis underneath.

Use two fingers to zoom and move the grid.

Touch the x in the top left corner to clear the screen.

To erase just a line, double-strike it out without lifting your finger, like in the graphic on the right.

Touch an expression’s tag for more information and options. You can copy or email an expression in various forms.

Touching the tag also bookmarks the expression in the top bar. You can drag bookmarks to the grid to reuse them.
