I have WinPilot Pro *and* a Themi. I can find thermals even when there
aren't any!

Okay, maybe not, but I'll offer this:

Both work as advertised and usually, but not always, agree with each other.
When first encountering lift, the Themi gives useful centering info before
WinPilot.

The Themi also remembers where previous thermals are, and even appears to
compensate for thermal wind drift with altitude when calculating this. As
you are approaching a previously used thermal, even at a different altitude,
the Themi will direct you towards it with remarkable accuracy.

I find both easy to use and intuitive, but the nod goes to Themi for
requiring almost zero in-cockpit looking.

All that said, if I already had Winpilot Pro, purchasing a Themi wouldn't
make much sense (I had the Themi first).

That is unfortunate for me, since I could not use it for an IGC logger,
and it's only value would be as thermalling aid.
