WhatsApp’s latest beta introduces a timer that erases messages after the recipient reads them, giving users tighter control over privacy and storage. The feature appears in both iOS TestFlight and Android beta channels, hinting at an imminent public rollout.

WhatsApp adds “After Reading” disappearing messages to iOS and Android beta builds

WhatsApp’s beta version for iOS now includes a new option under Settings → Chats → Disappearing messages called After reading. When enabled, a message can be set to disappear 5 minutes, 1 hour, or 12 hours after the recipient opens it. Unread messages still follow the classic 24‑hour timer.

Platform update

iOS – The feature is present in the latest TestFlight build (version 2.24.10). It lives inside the Default message timer section, even though it behaves differently from the existing 24 h, 7 d, and 90 d presets.
Android – A matching setting shows up in the beta channel on the Google Play Store. The UI mirrors the iOS implementation, confirming a cross‑platform design.
Release outlook – Both beta programs list the change as “available to a limited number of users,” which usually means a public release within the next few weeks.

Impact for developers

Privacy‑focused apps

If your app integrates with WhatsApp via the Share or Message intents, you now have an extra signal to respect. When a user selects a chat that has After reading enabled, the message payload may be deleted from the device sooner than expected. Consider adding a fallback storage strategy if you cache shared content locally.

Storage management

Disappearing messages have always helped users keep their chat databases small. The new timer reduces the lifespan of media files even further, which can lower the average size of the msgstore.db.crypt12 file on Android and the ChatStorage.sqlite on iOS. If your analytics track database growth, you should see a measurable dip once the feature is widespread.

Cross‑platform UI consistency

Both platforms expose the same three intervals, but the iOS settings UI uses a picker wheel, while Android uses a dropdown list. When building a companion app that mirrors WhatsApp’s privacy controls, you’ll need to implement platform‑specific widgets that map to the same underlying values.

Migration path for power users

Enable the feature – Open WhatsApp, go to Settings → Chats → Disappearing messages, tap Default message timer, and choose After reading.
Pick a delay – Select the interval that matches your workflow. For quick‑fire conversations, 5 minutes is a good fit; for longer‑form content, 12 hours gives the recipient time to react.
Test on both devices – If you use WhatsApp on iPhone and Android, enable the option on each platform to keep the experience consistent across devices.
Monitor storage – After a week, check the chat backup size in Settings → Chats → Chat backup. You should notice a reduction, especially in groups that exchange many photos or videos.

What’s next?

The beta also hints at future refinements, such as per‑message timers that could let you set a custom delay for a single chat entry. Developers building bots or automated responders should watch the upcoming API changes, as the server may start sending a read_and_expire flag for messages that are slated to vanish after being read.

By keeping an eye on both iOS TestFlight and Android beta channels, you can stay ahead of the privacy features that will soon become standard on WhatsApp.
