It’s weird in that it requires a few additional key presses: (1) make a text field; (2) write a formula enclosed in single dollar signs; (3) with the cursor anywhere in the text field, press enter, then backspace (this step is silly, but otherwise it doesn’t work); (4) press Esc.
Tableau Noir—has an eraser.
Tableau Noir—you can insert pages from pdf documents.
Both—no registration, no bullshit.
Both—work alright on ipad in the browser, although I have tried both only briefly.
