And it’s important to remember there are only 8 billion or so people on the planet, so there are no signs of its popularity waning anytime soon. Beyond being a hugely successful app, it’s also packed with features. You can use it to chat, make voice and video calls, share files, broadcast your location, and more. Even if you’ve used WhatsApp for years, you might not have discovered everything it’s capable of—which is where these tips come in. 1. Set a timer for messages to disappear You don’t necessarily want everything you say on WhatsApp to be remembered forever, and the app includes a timer feature that will automatically expunge messages in a chat 24 hours, 7 days, or 90 days after they’re read, unless you specifically keep them. This is set on a chat-by-chat basis, and affects everyone in a conversation. To change the setting for one of your chats, tap the contact or group name at the top of the screen, then pick Disappearing messages to select your time limit. This is applied until you turn it off or select a different period, but doesn’t affect the conversation history. 2. Lock away your most sensitive chats Put certain chats behind a lock. David Nield Another way of protecting sensitive information in chats is to add an extra lock to specific conversations. Even if someone should gain access to your phone and your apps, they won’t be able to see your locked chats. From inside a conversation, tap the contact or group name at the top, then pick Chat lock (Android) or Lock chat (iOS). You can then use a specific PIN code to block access to the conversation, or use the same biometric scan technology (such as Face ID) that already protects your phone at the lock screen. 3. Edit a message after sending it Have you noticed you can edit messages after sending them? It’s handy for those typos you only spot after dispatching a message—long-press on whatever you just sent, then tap the three dots and Edit (Android), or just Edit on the pop-up menu (iOS). Modified messages have an ‘Edited’ label visible to everyone in the chat, but they won’t be able to see what the original message said. Take control of who sees your activity on WhatsApp. David Niel WhatsApp can tell your contacts whether you’re currently using the app and when you were “last seen,” but this might not be information you want to share with everyone. As well as disabling the feature entirely, you can also turn it off for specific contacts. Open the You tab, then tap Privacy > Last seen and online, then select My contacts except … under the Who can see my last seen heading. You can then pick the contacts you don’t want to give this information to, and set the Who can see when I’m online option to match the same list. 5. Pin important messages you need to refer to or remember Important details can quickly get lost in WhatsApp conversations, especially in busy group chats. But there is a way to pin specific messages to the top of the chat so they’re easy to get back to—someone’s address or the start time of an event, for example. To pin a message on Android, long-press on it, then tap the three dots (top right) and Pin. On iOS, long-press a message and choose More > Pin. You can have up to three pinned messages per conversation, and select from three options for how long they’re pinned for: 24 hours, 7 days, or 30 days. Your contacts can have their own alert sounds. David Nield WhatsApp lets you assign specific notification sounds to specific contacts, which means you know who’s calling or messaging without picking up your phone. It gives you a better idea of whether something needs attention right away or can be safely ignored for a while. Tap the group or contact name at the top of a chat, then pick Notifications and Notification tone or Ringtone to make changes. You can also select Vibrate to customize vibrations for each chat, though there are only four options here. The option to mute the conversation is on the same screen—you can set mute separately for calls and messages. 7. Message yourself with notes and reminders Not all messaging apps let you have a conversation with yourself, but WhatsApp does. This might seem like a rather pointless (and lonely) way of using the messaging app, but it can be really useful for jotting down things you need to remember on the go, leaving yourself voice notes of ideas and thoughts, and so on. From the main conversation list, go to start a new chat, then search for “you” as the contact (or just enter your own username or phone number). 2026 Popular Science Home of the Future Awards 39 products that will improve your everyday life.
