If you choose to activate 7Minder in your profile you will receive little mindfulness push notifications during the day. You can also edit the frequency of the 7Minder notifications.
You can view these push notifications on your smartphone in the Notification Center where all push notifications are displayed. You'll get there by wiping the screen of your phone from top to bottom. If the messages are cut off in the Notification Center, you should be able to zoom in on them one by one.
