Reallang on your phone
Reallang on a phone is the student half of the product: the catalog, a person's page, a teacher's room, and the conversation itself. You talk out loud and get the same score you get in a browser, against the same published rubric. The teacher's desk is deliberately not here — that is a workplace, not a pocket.

Coming back to Google Play. The listing was withdrawn over a form, not over anything in the app, and it is being restored.
