Comments on SigmaCalculator for Android

★★★★★ A Google User · Feb 19, 2011

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

★★★★☆ A Google User · Mar 8, 2011

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

★★★★★ A Google User · May 21, 2014

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.

★★★★★ A Google User · Jun 6, 2012

Full-featured Scripting can now accept user input

★★★★☆ A Google User · Aug 28, 2011

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

★★★★★ A Google user · Mar 20, 2020

Lean and agile and does everything except symbolic manipulation

★☆☆☆☆ A Google User · 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.
