Open Sesame!

Hanging out, made easy

Open Sesame!
You shouldn't have to schedule to be with friends

"I feel like I never actually get to talk to [my friends] and then now I'm speaking to them like three hours a day, so to be completely honest, Sesame is probably the best... thing about [my school] so far."

- one excited student

See when friends are free

"The door visibility is the best part... I know when it's okay for me to talk to my friend"

Open Door = open to chill
Closed Door = busy, don't disturb

You can join your friends' calls too, the more the merrier!


50% talking 50% studying :)
