Doceri

Doceri is the greatest tool that I have found.  (I wish I had more time to use it)

Doceri is an app, but it also has a desktop version that works along side the app. I have only used the app, but I shared my fine with a High School Math teacher now she creates all her lessons on it. She says it has been great for creating the figures needed when teaching geometry.

Doceri allows you to create videos, slides and insert pictures as needed.

I used it to create videos of worked out math examples for my students to access when they need them. I created them in Doceri, exported them to dropbox, then uploaded them to my Weebly website.  This way the students can get to them any time they need.
