I would like to share my situation with you: I want to a teach geographically-distanced person some mathematics. I've been trying to explain things over the phone, but I feel that visual explanations would be more helpful. That person only has an Android smartphone (no laptop/PC). Do you know of any collaborative whiteboard app where we will be able to sketch together (online)?
A few preferences:
- I don't have a smartphone. It would be awesome if said app will be multi-platform. I.e. I will use a browser application and/or a Windows application, and the other person will use an Android smartphone.
- If you only know of an app that requires two smartphones, you can also mention it. (It will be less comfortable for me as I'll have to borrow a smartphone from a family member, but perhaps it will still help someone else.)
- If said app will be more math-savvy, that will be a big plus. (E.g. instead of just scribbling with a virtual pen on the whiteboard, it will be great to be able to draw tables and geometric shapes, write text, etc.) The mathier, the better.
