There is no submit button! Your story is sent out every day at midnight, and you receive your partner's story at a time you specified. This way, you can share the little details without disrupting him or her while sleeping or during a meeting. You can go through the story by flipping through the frames. Each frame prominently displays the time it was created in the other person's time zone.
The app will also display the current time where your contact lives. And you can also set reminders to fill you story if you need to. This app is also great to use with a parent or a friend who lives far away. So you also have the ability to add more than one contact.
