/drawsesh
DrawSesh is a mac app for timed drawing sessions, using your own references from a designated local folder. I made this for my own figure-drawing sessions, but since you can set what images are used, you can use it to practice drawing whatever you want: portraits, animals, fabrics, etc.
Load your folder and customize your draw session.
Controls for your session. The bar will hide itself.
A history log to track your consistency and reference past sessions.
