BLCK NOTES Get the app

Voice notes that disappear when you say so.

You own every note you send. Unsend it from everywhere, allow one listen, or set it to disappear after 24 hours or 7 days. There is no time limit on that control.

Download on theApp StoreFree on iPhone. App Store link is a placeholder until the listing is live.

Unsend anytime

Take a note back from every inbox and the web player at once. There is no two-minute window. If you unsend it, the link stops working.

Listen once

Each recipient can play the note once. A play counts when the audio actually starts, never when a page or a Messages preview loads.

Disappear after 24 hours or 7 days

Or never, which is the default. When time runs out, the note is removed for recipients. You keep your own copy until you delete it.

The same rules on every phone

Because Black Notes sends a link, not a file, the rules you set hold in the app, in iMessage, and in any browser.

How this is different from iMessage

Apple's expiring audio is a setting the recipient controls. Undo Send lasts about two minutes. In Black Notes, the sender controls everything, with no time limit, and the same rules apply on any phone or browser.

Recipients can't download this note unless you turn saving on. Anyone can still record a screen or hold up a second phone, so we never promise a disappearing note can't be kept another way.

Questions

What does a disappearing voice note do?

You choose when the note is removed for recipients: after they listen, after 24 hours, after 7 days, or never. Never is the default. You keep your own copy until you delete it.

How is this different from iMessage’s expiring audio or Undo Send?

Apple’s expiring audio is a receiver setting, and Undo Send lasts about two minutes. In Black Notes the sender controls unsend, listen-once and disappearing, with no time limit, across the app and the web player.

What is listen-once?

Each recipient can play the note once. Opening the page or loading a link preview does not use up that play. A play counts only when the audio starts.

Can I unsend a note after it has been heard?

Yes. Unsend works at any time. The note leaves every inbox and the web player, and the link stops working.

Can recipients download a disappearing note?

Recipients can't download this note unless you turn saving on. Saving is off by default.
