Meta-owned WhatsApp is rolling out a new disappearing messages option to some iPhone beta testers. The feature, previously spotted on Android, lets users delete messages after they are read, with post-read timers of 5 minutes, 1 hour, or 12 hours. Unread messages are automatically removed after 24 hours. The feature is available in WhatsApp beta for iOS 26.19.10.72 and works alongside the existing 24-hour, 7-day, and 90-day disappearing message timers.
