Having worked as a tutor and a software developer, I've seen a lot of live whiteboard apps, but none that had all of the following:
- Mobile-friendly controls
- Support for math typing
- Persistent rooms with custom names
- Free usage of all features with no signup required
So I made one! If someone you know might find it useful, send it their way. Also, it's open source: https://github.com/tylerb1/whiteborb-public
I write about books, politics, mental health, music, and whatever else.
