Yes, I believe there are a couple. If I'm not mistaken the Reyburn software does and I know Tunelabs runs on laptops because I use it on my IBM.
Evaluation copies of Tunelabs are available free, 300kb, on the internet and possibly through Robert Scott, its creator: Robert Scotts Page
At $35, if you like it and are honest, its the cheapest way to go. It will construct a stretch curve based on your sampling a number of notes and doing some interpolation, or you can just get a hold of David Porritt's add-in for another $10, which will do it automatically.
The program is not teaching software. It assumes you understand the basics of hammer technique, stretch, setting unisons and that you can navigate your way around the windows environment. That said, its quite impressive at nailing the right stretch and giving you a piano that rings the way it ought to, when finished. IMO, it is to the majority of aural tuners what ABS brakes are to the majority of racing drivers. That is to say better. The sample and registered version are functionally the same.
There are some RPTs using it, so I imagine it is competitive with Reyburn and the others. My advice to anyone working with it is to turn off the other programs that you may not know are running in the background by hitting
and selecting end-task for everything, but explorer. This way your hard drive will shut down letting the microphone, which is standard on most portables, hear better.
