## Most critical reviews (4 lowest-rated)

### 1/5 — Crashes

*2015-10-22*

The app is unable to cope with 0 shear stress and crashes instantly,

An obvious thing to have tested, so consequently you can't have much confidence in the rest of the app.

### 3/5 — Lacking

*2011-01-24*

So this app definitely needs more input fields... The only inputs are sigma x and sigma y, which only through trial and error did I figure out was sigma n (normal stress) and sigma s shear stress. In addition there was a  field T(x,y). One of the primary use cases of a mohr circle is to find those sigma x and sigma y, so this is kinda backwards for that. Ui design and aesthetics are top notch however. I'll add stars when this app becomes useful.

***update: Please, add support for coulomb failure envelope.  And also please add a parameter for pore pressure, making this useful for structural geology.

### 4/5 — Decent

*2011-02-18*

Would like to be able to rotate the stress block to calculate the stresses on a plane inclined from the horizontal. Otherwise very handy.

### 5/5 — Perfect

*2010-12-15*

Great tool, great app! Shows result in 4 nice graphical views as well as a table for easy reference. Saves information as states for easy lookup later.
