I noticed on Pocket Mechanic's download page they changed from version 2.17 to 2.16.

2.17 was there for a while, I wonder if there was a problem with 2.17? The change to 2.16 seems deliberate.

I'd ask on their forum, but it's been offline for several weeks.

"I'm a perfectionist, but not very good at it yet."

Their site should be back up tomorrow.
I guess we'll find out then, probably with a newer version.

Well unfortunately it appears that their having greater difficulty than they anticipated transferring the site to new servers so the forum is still down.
