<ul class="set"> <li><b>Today's Activities:</b> tap one to start it.</li> <li><b>Start a scan:</b> a quick reading of heart rate and breathing, under a minute.</li> <li><b>Join a session:</b> enter a room code to join a live session. See <a href="https://presagetech.com/docs/essessment/app-live-session">Join a live session</a>.</li> </ul>

To choose what a quick scan shows, tap the measurements line on [Today](https://presagetech.com/docs/essessment/app-today). You can show heart rate, breathing rate, heart rate variability, and pulse, breathing and EDA waveforms. At least one has to stay on.
