Smart phones have become an essential tool for many of us.  We can access the internet to get driving directions or check the weather, take pictures and videos to share with friends and family, use a calendar to remind ourselves of appointments, phone anyone including when our cars break down or in case of emergency, play games, and text and email.  We can also text photos and create documents.  Some apps such as Google Meet allow us to have video calls with friends and family.  Cell phones can also be used as audio recording devices.  If you don't have a smart phone I highly recommend getting an Android or Iphone.
