10 Crazy WhatsApp Facts You Probably Didn’t Know

10 Crazy WhatsApp Facts You Probably Didn't Know


  • WhatsApp’s co-founders were rejected by both Facebook and Twitter
  • The Android app clocked 1 billion downloads with just 5 people
  • You can see when your messages were read

WhatsApp, the messaging platform that cost Facebook $19 billion dollars when it was acquired back in 2014, remains the most-used IM service with its parent’s own platform – Messenger – following suit. And while you (probably) use it every day, there might still be some things that you don’t know about its operations or what you can do inside the app. Here are ten things you likely don’t know about WhatsApp:

1. 1 billion downloads with 5 people
The messaging service hit the 1 billion downloads mark on Android back in March last year, and WhatsApp co-founder and CEO Jan Koum posted in response that the team working on the Android version was just five people in total.

WhatsApp crossed 1B Android downloads. btw our android team is four people + Brian. very small team, very big impact.



2. The company’s co-founders were rejected by Facebook and Twitter
Both Jan Koum and Brian Acton – who earlier worked together at Yahoo – were rejected by Facebook and Twitter in interviews, before they went full-time with WhatsApp. Imagine how different the world would be if even one of those interviews had gone better.

Facebook turned me down. It was a great opportunity to connect with some fantastic people. Looking forward to life’s next adventure.




Brian Acton @brianacton

Got denied by Twitter HQ. That’s ok. Would have been a long commute.



3. You can use WhatsApp to compress images and videos
Sure you could use a dedicated photo editing app to do that, but this works great for a quick fix if you don’t mind the drop in quality. Send the set of pictures and video files to one of your friends (or yourself) via WhatsApp, and then head over to the WhatsApp Media folder on Android or your Camera Roll on iOS to find the compressed versions. You can delete the originals to save space, or share the compressed images or videos through some other if you prefer.

4. WhatsApp creates user account in the form of [phone number]@s.whatsapp.net
The service runs a customised version of the open messaging standard XMPP (Extensible Messaging and Presence Protocol), which was first developed for collaboration application Jabber. That’s why WhatsApp uses the ID protocol made for Jabber in the form of <[phone number]@s.whatsapp.net>

5. Type “whatsapp://send?text=HELLO” in browser address bar
The messaging service has its Web protocol as well, which is used by most websites to create a WhatsApp share feature. If the phone has WhatsApp installed, typing the text above into your browser should open WhatsApp and ask you to choose a contact to send the message to. You can customise the message by replacing the word “HELLO” with whatever message you’d like to send. Put in a little though and it could be a good way to prank friends into sending messages they didn’t mean to.

6. See when your messages were read
Sent a message and later saw that it has been delivered and read, but you’re not sure when? WhatsApp displays a couple of different ticks to tell you about the status of your message. But it also goes one step further and gives you a timeline breakdown on when your message was delivered and read. Just hold on any particular message and choose ‘Info’.

7. Custom notifications for any contact or group
Right now, pretty much every message you get on WhatsApp probably sends the same notification, right? So the only way of knowing if it’s something important is to check your phone every time a message comes. But there’s a better way of doing things. You can set up custom message sounds, ringtones, vibrating patterns and pop-ups for your WhatsApp contacts and groups, depending on what device you’re using. iOS is the more restrictive one, allowing for only sounds and ringtones. On Android, you can do all four – even going so far as to choose any sound file for calls, picking between short or long vibrations, and so on. This means that you can have different notifications for your work groups, your friends, and your family.

8. Text formatting – bold, italics and strike-through
Since March, WhatsApp for Android and iOS has supported basic text formatting as well in quite simple fashion, by enclosing your message in asterisks for bold, underscores for italics, and tildes for strikethrough. You can also combine any of the three for a multi-formatted experience.

The reason WhatsApp Web needs your phone and its corresponding data services to work is because the company doesn’t provide server storage for your messages, unlike Facebook Messenger or Skype. All the server maintains is a queue of your undelivered messages. Once a message gets delivered to your device, there’s nothing left back on the servers. You can of course backup and restore your messages via Google Drive or iCloud.

10. WhatsApp provides 256-bit end-to-end encryption
Developed by Open Whisper Systems – whose encryption protocol has been used by famed messaging tool Signal for years – all messages sent and received through WhatsApp are now encrypted end-to-end which means hackers or oppressive regimes cannot breach your privacy. This move has thrust WhatsApp into the legal world limelight since then, since it means that messages cannot be lawfully intercepted either.
