PoseViewer

A free and simple desktop app where you can use your own images to practice gesture drawing.
How to use the app:
Click on the briefcase icon next to the "Choose folder" text.
Drop your folders with your images there. Do not drop only images. That is so you can make collections of images. The images must be .png or .jpg.

Click on the lens icon next to the briefcase icon for the folders to appear.

Choose your folder, the interval between poses and the quantity you want to draw. If you have less images than the quantity a message will appear warning you and the slideshow won't start.
You can Pause, Go to next or Refresh the current image.

Or watch the youtube video where I explain briefly what to do, give it a like so that others may see it!
Enjoy.

I do not have a mac to test the app but it should be working...
