Twitter has released an update that allows users to see how many times their tweets have been viewed. Technically, the public has always had access to this information. When viewing your tweet, you can click the View Tweet Activity button. This would display a plethora of information about that tweet. People want to save a tweet so they can access it later. People would usually just retweet it and then go to their profile to do so.
Twitter addressed this issue by allowing users to bookmark tweets. The company announced this in a tweet, but it did not specify when it would be available on Android.
