Well, if you mean are they fingered exactly the same, no. 

If you mean are they are made up of the same musical notes, yes.

Like a C major chord is CEG on both guitar and violin, and piano, and everything else that can play a chord.

But if you mean "is the fingering the same on both instruments for the chords", no. Different instrument, set up and tuned in different ways

There is, however, a somewhat useful trick for folks that already know chords on guitar and are learning to play violin.  Notice how the 4 lowest pitched strings of the guitar are EADG, and the strings of a violin are GDAE?  Same notes, but which is highest and which is lowest happens to be exactly backwards.  That's because the violin is tuned in 5ths and the lower strings of a guitar are tuned in 4ths.  If you know how to play a G major chord in open position on guitar, you know you finger G on the E string, B on the A string and play the D string and G string open.. Well, you can do that on those strings of the violin too, and it will also be a G chord.  And the way the notes look on the violin fingerboard will be like a mirror image of how you would play them on a guitar.

So chords and scale sand patterns you learn on one of the instruments *can* help at least a bit with finding them quickly on the other instrument.   As such, your software you found might be of at least a bit of use for you.

Hope that was clear enough to help a bit.
