You can now save posts you’d like to revisit later.
Now you’ll see a new bookmark icon underneath posts in your feed. Simply tap it to save a post to a new, private tab on your profile. There you can see all the posts you’ve saved—and they’re only visible to you.
For Instagrammers stumbling upon a business they want to remember, a new product they like, or a memorable ad, they can now keep track of favorite posts right from their profile.
To learn more about saved posts, check out the Instagram Help Center.
Saved posts are part of Instagram version 10.2, available today for iOS in the Apple App Store and for Android in Google Play.
