Your Activity Dashboard shows you how much time you've spent on Instagram for the past day and week, as well as your average time on the app. You can tap and hold the blue bars to see how much time you have spent on Instagram on a certain day.
Choose how much time you want to spend on Instagram every day. Set a daily reminder to give yourself an alert when you've reached the preset time.
Use the mute push notifications feature to silence Instagram notifications for a period of time. When the preset time is up, notifications will return to their normal settings without having to reset them.
