【實用社交app】Formula Learn|最夯免費app-綠色工廠好玩App

Formula is an anonymous social network enabling users from across the world to interact in a fun, easy way. With the Formula Learn app, you can draw, erase, drop geometric objects, graph equations, write text, snap photos, annotate documents, and type text -- it all goes on your whiteboard, which you can then upload and share with the whole world.

From the app itself, you can browse a list of rooms recently posted by other users, edit their whiteboard contents, and post your revisions as a reply.

A hyperlink to a URL of the form formula://open/[board-url]/[post-number] is interpreted as a request to download the whiteboard found at that URL & open it for editing.

When posting a new thread, you can also specify up to 10 email addresses that will receive a message with a link to the thread on the website. This email includes a direct link to download the whiteboard for those recipients who have the app installed, as well as links to download the app itself. Users can easily opt out of such emails.
