Further down, you'll see two options for managing your time: Set A Daily Reminder and Notification Settings. Daily Reminders simply ask you to choose how much time you'd like to spend on Instagram each day. When your time is up, you'll get a notification telling you as much, which you can choose to ignore or use as a cue to log off. Notification Settings lets you mute notifications for a length of time up to eight hours. You can also specify which notifications you want to receive — for example, only likes from people you follow — and which you don't want cluttering your lock screen.
