I’m having the adults on this trip try TRIPI. (You like my alliteration?!) here’s how to do it:1) have the search for the app (it probably won’t just pop up when they type it in).2) give them the ID code 3) they will be “logged in” And will show up in your “members”. there will be a delay from your lips to their ears but it actually works well if they’re not looking at you (leading a walking tour/dark of night).id definitely suggest it for adults, particularly in groups of 40 or more. With multi-bus if the lead wants to speak to the entire group all members (including other EPLs) can log in with the ID code. you have to tap the red “play” button at the bottom of the members tab To send thrm an invitation/alert that you’ll be talking. you can ”log/move/tap/tab” out of the members and it will say “stop counting” (like it’s a really big deal). click on ok - nothing will happen. You HAVE to so you can tap on the “start guidance”. Trouble shooting: if they can’t hear you through their headphone/air pods they may need to turn their phone off and on to “connect” with the app.
