Approved Really good features for plotting and statistics, given that it's free. Could use more functions, though, like calculus, complex numbers, bit operatio

by Miguel the 6/19/2011

Cannot solve expressions when a constant multiplies a variable, like 8-2x²=0 (it will solve 4-x²=0 though). Will change my rating if this is fixed.

Processes formulas and let's me type from the physical keyboard. Awesome!

by janger the 4/25/2011

Now the variables are saved permanently I'm giving this 5 stars. Great app. Thanks.

by Eric the 3/31/2011

Great app. Should include complex numbers to make complete.

Very good...helped me alot on my homework

Doesn't remember degree/Radian choice when restarting phone. Animation when answer appears is annoying - would be better to have a two line display.

by Ace the 2/19/2011

Can a formula be entered with various unknowns and then solve for the unkown? Will the solver rearrange the equation automatically?

by triguy616 the 2/17/2011

This is a great free app! Has all the functions I was looking for, plus you can type the whole expression before calculating.
