Have You Seen Puzzilla?

Puzzilla is a FamilySearch companion App. 

 First thing to do to get it is to sign into FamilySearch and click on App Gallery at the bottom of the page. Choose Puzzilla and see this.

 

You don't need the paid service; the free one is just fine. 

Click on Get Started and you will come to the Puzzilla sign-in page.

 When you sign-in it will take you to the FamilySearch sign in to link the two programs together.
You will then see a permission to connect box.

Click on that and the fun begins.
This is what happens if you have the generations set at 6.

I'm the green dot down there at the bottom. If you click on that dot, my information shows up. You can click to see my descendants or back to see my ancestors as it is shown now. You can click on View in Family Tree and go to my person page. You can click on any dot on the page, see who it is and their ancestors as far back as you have research done in FamilySearch.
THEN, you pick an ancestor and make them the center and ask for their descendants.

It now shows an ancestor, Stephen White with the yellow trail through my GG Grandmother, G Grandfather, Grandmother, and my father. You can click on any dot and find a direct line ancestor or a sibling of theirs, or spouse and cousins by the dozens. You can see where the ends of lines are so that you can do research. Red dots are girls and blue are boys. The red or blue dot with a gray box beside it means that the person falls within the 110  years. A yellow box beside their dot means that they died before 16 so probably didn't have any children.
There is a How To option at the top to learn how everything  works.
There is also a log with interesting features. It helps you keep track of status indicators that you define. It also has LDS ordinance indicators that show you when work has been done, good for keeping track if you have shared cards with others.
