Run a live session

A session is you and your student in a room at the same time, on one board, with voice. It is the live half of the app; a tutorial is the half a student walks alone.

Start one

In the Teach tab, on the New session card, press Start to open a room with you leading it. Nobody types a code: your students see In a session now with your name on their Home tab and press Join. Only your own students can come in. You must be signed in; a guest is taken to the sign-in screen first.

Only one session at a time. Starting a new one ends the one you had open, for everybody in it. If you are still in somebody else's session, the app asks Leave the other session? first.

Call your students in

From inside the room, Invite students to session sends an invitation that pops up on the student's screen. Tick names one by one, or tap a group to tick everybody in it.

Inside the room

Everybody sees one board. The trainer moves on it, and students too once the trainer turns on Students may move. The left column has two parts, Board and Library:

Voice. The microphone or headset in the room's bar shows your voice's state; tap it for the voice panel. Nobody's voice is on until they press Turn on voice themselves. While somebody is talking and yours is off, a strip under the room's bar names them and offers Join voice. A student asks to speak with Raise hand to speak and takes it back with Lower hand; the trainer mutes or gives the microphone to each student on their row, and Leave voice drops the audio without leaving the room.
Answering without a voice. Under a student's board are Show my position to trainer and three ready answers — Yes, No and I didn't understand — which work whether or not the voice is on.
Drawing. Arrows and coloured squares go on the board for both of you, with Undo arrow and Clear all arrows.
The board. In the trainer's left column, Set up position…, Paste FEN… and Import PGN… put a position on the board; Export PGN, Save position and Save analysis keep it. A student's column has only those three.
The moves. The right column holds the engine at its top (the trainer's alone), then the move tree, To main line, Delete variation and the comment. On a phone held upright the tree comes right under the board and Comment… opens the comment on its own.
The library in the room. The room's list is the same library as on the Teach tab, narrowed to Tutorials and Positions, with Mine and From trainer beside them, the labels you gave your positions, and a search field that reads titles and labels alike. Tapping a row puts it on the board; a tutorial starts from its first part. A row's Edit tutorial opens it in the Tutorial Studio.
Carrying on elsewhere. The ⋮ in the bar has Export to Analysis, which hands the position to the analysis screen, and Settings.
Who may do what. The trainer's Session button opens one panel: who is Present in classroom, Invite students to session, Students may move, which opens or locks the board for everybody but you, Force student board to:, and Room access, which narrows who can come in. Whoever started the session leads it; that does not change while it runs. The engine is the trainer's alone: a student has none in the room.

Leaving, and coming back

Whoever started the session has End session, which ends it for everybody and sends them back to Home with The session has ended.; invitations to it stop working. Everybody else has Leave session, which ends only their part of it. If you simply walk away — another tab, the back button, closing the app — a band stays across the top of the app with the room's code in it, and Resume session puts you back on the board.

Recording

A session is not recorded. The room has no recording button, whoever is in it — not even a trainer alone waiting for a student.

Recordings you made earlier are kept: they are under Recordings on the Home tab and in the Library on Teach. On that screen the spacebar plays and pauses.

What can go wrong

The invitation has no Join — it says This session has ended.: the trainer ended that session or started another. Look at In a session now on Home, or ask to be invited again.
Nobody hears anybody — read the voice panel first: a voice that did not start says why in red above the button, and a microphone that does not work says so in the panel. Then check that the microphone is allowed for the app in the operating system, and that neither side has pressed Leave voice.
The student cannot move — a new session starts with the board locked; the trainer turns on Students may move.
