I need 2d animation app for linux anons. It should be simple and free. Is there something like that for this shit OS?
Google. Its your best ally (note, sarcasm)
Tupi, its waaaayyy to simple, but it may be what you want.
Synfig if you are mad and crazy.
Pencil 2D if you are doing hand drawn animation frame by frame and you dont mind a featureless software.
And blender, just blender, be its friend
