From the developer:
QuickTTestX is a programme for calculating means, SDs and SEMs and testing the significance of differences using Student's t-test. Its main advantage over other statistical programmes is that data can be input not only as individual values (from the keyboard or by import from a text file) but also as mean ±SD or mean ±SEM for groups.
