Your board, unchanged.
Now it speaks, remembers, and keeps a record.
Nothing is attached to the board but six stickers. The camera can sit anywhere. Camera frames never leave this phone.
Put the phone on a desk stand, a tripod, or the partner's shirt clip. Boardvoice finds the board by its stickers in every frame, follows the index fingertip, speaks each letter and word, and saves a transcript. No camera? Screen mode puts the board on a tablet or a video call. The board, the partner, and the method stay exactly as they are.
