Who sees what, in one minute

boopr has no public posts and no followers. When you tap "Post", your phone locks the post to the exact set of friends you picked, and each of those friends gets their own key to open it. We can't read the post, and we never learn your list names; the choosing happens on your phone.

Three rules follow from that design, and the rest of this guide is mostly the details of them:

  • The audience is fixed at the moment you post. Editing a list afterward never changes who can see a post you already published.
  • Posts can't be edited. You can widen a post's audience one friend at a time, or delete it. That's the whole menu.
  • The feed shows the last 90 days. Older posts don't disappear; they live on each friend's profile.

Writing a post

Tap the pencil button on your feed. A post can be text alone (up to 500 characters), a photo, a GIF, an album of 2 to 20 photos (boopr+), or a video up to 3 minutes (boopr+). With media attached, the caption can run 300 characters.

  • GIFs come from your photo library. There's deliberately no GIF search: typing into one tells a third party what you're looking at, so boopr doesn't have one.
  • Photos are treated identically for everyone: resized to at most 3000 pixels at high quality. Image quality is not a paid feature.
  • boopr keeps one draft. If you leave the composer with anything typed or attached, it's waiting when you come back, for 7 days.

When you tap "Post" you're done. The app returns to your feed and finishes in the background, showing a card with its progress. If it can't get through you'll see "Failed to post" with "Retry" and "Dismiss". Retry is safe: even after a crash or a force-quit, boopr makes sure a retried post is never published twice.

Choosing your audience

The chip above the keyboard shows who will see the post. It starts at "All Friends" on every new post; your previous choice is never carried over, so a narrow audience can't follow you to the next post by accident.

Tap the chip and "Who can see this?" opens: keep "All Friends", pick one or more lists, pick individual friends, or mix them. The footer counts real people, "12 friends will see this post", so a mixed selection is never a guess.

After you publish, a post that went to a list or to specific friends shows its audience on the post, but only to you. Friends never see the label, never see which lists they're on, and never learn that lists exist at all.

Lists, and the snapshot rule

Lists live in the side menu, under "Lists". You can have up to 20, named 2 to 50 characters, each holding any number of friends, and a friend can be in several at once.

The one rule that matters: a list is read at the moment you post, then never again. The app tells you this whenever you edit one: "These changes only apply to new posts. Past posts to this list won't change." Concretely:

  • Add someone to a list, and they'll see future posts to it. Posts already published stay invisible to them.
  • Remove someone, and they keep every post they could already see.
  • Rename or delete a list, and nothing changes for any published post. Old posts keep showing the name the list had on the day you posted.

You can't unshare by editing a list. If a post went to the wrong people, removing them from the list won't take it back. The only way to take a post away from someone is to delete the post.

After you post

There's no post editing on boopr, so a published post can change in exactly three ways:

  • Widen it. On a post that went to a list or specific friends, tap its audience label, then "Share with someone" to add one friend at a time to that single post. They receive it like a new post. There's no way to narrow an audience.
  • Delete it. Deleting is permanent and immediate: the post vanishes from friends' feeds right away, along with its comments and likes. There's no undo.
  • Remove your own tag, if someone tagged you. More under tagging below.

Comments

Comments on boopr default to private. A reply you write is visible to the post's author and to you, nobody else, unless you choose otherwise.

  • The chip above the reply box reads "Private" or "Everyone". Tap it and "Who sees your reply?" lets you pick. "Everyone" means everyone who can see the post, never anyone beyond it.
  • The choice is permanent for that comment, and there's no comment editing.
  • On your own posts, your replies are always visible to the whole audience. There's no private reply on your own post.
  • Private replies are invisible to everyone else, including the fact that they exist. Two friends can see different comment counts on the same post, and both counts are right.
  • Only the person who wrote a comment can delete it. As the post author you can't remove someone else's comment, but you can report it with a long press.

Comments can run 2,000 characters.

Likes

Double-tap a post or tap the heart. A double-tap only ever adds a like, so an accidental one can't take a like back; the heart button is the toggle.

  • Everyone who can see a post sees its like count.
  • Who liked it is for the author alone. On your own post, tap the count to see names. On anyone else's post, no such list exists.
  • You can't like your own post.

Tagging friends

On a photo or video post you can tag up to 20 friends: tap "Tag" in the composer, tap the photo where they are, and pick the friend. Tagged friends get a notification.

Tagging adds them to the audience. Tag a friend on a post that's shared with a list they're not in, and that friend can now see the post. A tag is an invitation, not just a label.

If you're tagged in something, you can take your tag off: long-press your name label on the photo, or use the post menu. Removing your tag doesn't remove your access to the post, and the author isn't told. Authors can't add or remove tags after posting.

New friends, former friends

When you become friends with someone, your past posts that went to "All Friends" are shared with them automatically, from your phone, in the background. Posts made to lists stay put: a new friend never receives a post they weren't chosen for at the time. Your older posts appear on your profile for them; only recent ones show in their feed.

If you'd rather new friends start from zero, turn off "Share Post History" in Settings › Notification Settings. It's on by default, and turning it off only affects friends you add while it's off.

When a friendship ends, it ends in both directions at once. Unfriending removes their access to all of your posts and yours to all of theirs, immediately. Likes and comments that were already made don't retroactively vanish for the people who can still see the post. Reconnecting later takes a new friend code.

  • Blocking is unfriending plus never seeing them again. They aren't notified.
  • Muting is cosmetic: their posts hide from your feed, but the friendship, their access, and everything else stay intact. Unmute any time in Settings.

Limits and quirks

  • The feed crops very tall or very wide photos to keep scrolling sane. Tap any photo to see the whole thing.
  • The feed ends on purpose. "You're all caught up" means there's nothing hidden below; anything older than 90 days is on your friends' profiles.
  • Screenshots of posts notify the author. See what happens if someone screenshots.
  • A list with no members technically publishes a post only you can see; the picker warns you with "0 friends will see this post".
  • The numbers: 500 characters per text post and 300 per caption, albums of 2 to 20 photos up to 200 MB total, GIFs up to 15 MB, video up to 3 minutes, 20 tags per post, 20 lists, 2,000 characters per comment, and up to 1,000 friends.
  • boopr+ gates albums and video. Everything else in this guide works the same for everyone.
