What is a one-sentence summary of the following article?
Tap the Twitter app icon, which resembles a white bird on a blue background. Doing so will bring you to your Twitter feed if you're logged in. If you aren't logged in, enter your username (or email address, or phone number) and password before proceeding. It's a circular icon in the top-left corner of the screen. Doing so prompts a menu to appear. This option is in the menu. This will take you to your profile. Scroll down through your profile until you find the tweet that you want to track, then tap the tweet to expand it. The number to the left of the Retweets options will tell you how many people retweeted your tweet. For example, if 100 people retweeted this tweet, you'll see 100 Retweets below your tweet. Tap Retweets below the tweet to bring up a list of people who have retweeted your tweet. You can close this list by tapping the "Back" button in the top-left corner of the screen. It's near the bar graph-shaped icon below the tweet itself. Doing so opens the "Tweet activity" page. Near the top of the page, you'll see an "Impressions" heading and a number. This refers to the number of times your tweet has been viewed.  This includes times that your tweet appeared in other people's feeds because of other accounts liking or retweeting the tweet. The number of impressions that your tweet earned doesn't reflect the number of people who saw your tweet due to the fact that someone can view your tweet multiple times. This blue button is in the middle of the screen. Tapping it will bring up a list of things like the number of retweets, the number of likes, and the overall number of engagements that your tweet received.

Summary:
Open Twitter. Tap your profile icon. Tap Profile. Find and select your tweet. Review the number of retweets. View the people who retweeted the tweet. Tap View Tweet activity. Check the "Impressions" number. Tap View all engagements to see more information.
