Snapchat is now worth $US15 billion, making it one of the most valuable private tech companies in the world.
So what’s all the fuss about? If you’ve never used Snapchat before or you’re confused by how the self-destructing photo and video app works, you’re in luck!
I’m 22 and I use Snapchat obsessively. Here are all the basics, as well as everything you never knew you could do on Snapchat.
There are buttons you can push to turn on and off your camera's flash, as well as to toggle between the back-facing camera and the front-facing, or selfie-mode, camera.
You can see your Snapchat score, the total number of snaps you've received and sent, on your profile.
Other people can add you by pointing their phone at the ghost on your profile and tapping their screen. If you want your friends to easily find you on Snapchat, you should share a screenshot of your Snapchat profile to Twitter or Facebook!
But before you do any of the fun stuff, you're going to want to go into your settings. You can do this by tapping the gear wheel in the upper right hand corner of your profile. This screen will come up. Make sure you turn on your filters! The replay feature allows you to replay one of your friend's snaps a day. Otherwise, all the pictures and videos sent on Snapchat are gone after you see them the first time.
OK, now we can get into the interesting stuff. Press the circular button to take your picture. If you're taking a video, press and hold. Most of the following will still apply to you.
Ta-da! There's your picture in its most basic form. Once you send this picture, your friends can only see it once before it's gone. They can screenshot it, but you'll see that they did.
Your Snapchat Story lets you share a photo or video with all your Snapchat friends for 24 hours. Unlike a normal Snapchat photo or video, which you can view once, Snapchat Stories can be viewed again and again until they self-destruct 24 hours after their time of publication.
You can tap through the palette to choose your colour, and then have at it. use your finger to doodle all over your picture.
Snapchat hack: If you're on an iPhone, you'll notice white and black are absent from the colour palette (Android users have them built in). You can get the white crayon by touching the palette and dragging your finger towards the top left corner. To get black, touch the palette and drag your finger toward the bottom of the screen.
And there are geolocation filters! The Manhattan one is fun. When you're all set, tap the arrow at the bottom to figure out who to send your snap to.
Snapchat shows you the people who you end snaps to most frequently in your 'best friends,' at the top of your contacts. Below them you'll see recent contacts. Below that, your snaps are organised alphabetically. Once you're ready, press the arrow to send your snap!
Incoming videos are in purple. If you are about to open a video, make sure your sound is on so you can hear it.
Snapchat hack: When the person you're talking to is chatting with you, the yellow button turns blue. If you and your friend both hold down that button at the same time, you can do a live video chat with that person. It's kind of like FaceTime.
