Much of the software representing itself as piano tuning software is chromatic tuning software. Chromatic software is not suitable for tuning pianos.

In order to tune a piano, one note, usually A4, is tuned to a reference pitch. Then, the rest of the piano is put into harmony with that note.  This is done by matching partials

Chromatic tuners do not match partials.  They simply generate mathematically correct half-steps.  This is insufficient because pianos do not generate mathematically perfect partials. Pianos tuning is based on matching partials… mathematically imperfect partials.

Below is a list of tuning software and devices that consider partials in their calculations:
