The first version of this software provides a host of features such as;
Exact mass and natural abundance as specified by NIST
Gaussian peak shape of user-defined width
Summed peak envelope rather than a nominal mass stick spectrum
Isotope pattern drawn on the screen
Copy and paste to MS Word etc.
Export the envelope to a text file for MS Excel etc.
All stable isotopes of all elements covered - H to Uuu
Enter more than one element - SnCl4
