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

This is a great free app! Has all the functions I was looking for, plus you can type the whole expression before calculating. Update-After 3 years, still an amazing calculator, and updates come regularly to address issues.

Approved Really good features for plotting and statistics, given that it's free. Could use more functions, though, like calculus, complex numbers, bit operatio
★★★★★Ace· Feb 19, 2011
Can a formula be entered with various unknowns and then solve for the unknown? Will the solver rearrange the equation automatically?
★★★★★amnon nissan· Mar 20, 2020
Lean and agile and does everything except symbolic manipulation
★☆☆☆☆Miguel· Jun 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.
