Nine things you didn’t know your Apple Watch could do… from tracking your partner’s heartbeat to unlocking your car

NOT since the invention of the iPhone has Apple developed a product more jam-packed full of new features than the Apple Watch.

Having been on the market for over two years, the Watch has made itself a must-have for followers of the tech giant, and is slowly becoming one of their most popular items.

But with so many people getting behind the smart watch, are they all really making the most of its full capacity?

From interacting with your car to ordering your dinner, the Watch's capabilities seem almost endless.

Here are 10 things you probably didn't know your Apple Watch could do.

Unlock your car doors

If you have a connected vehicle, the Watch offers apps that allow you to interact with your car.

BMW, Tesla, Volvo and Hyundai are among a host of car manufacturers that support applications allowing users to perform tasks like unlocking their car doors, starting the engine and checking the battery levels, all from the tiny wrist-mounted computer.

Stay close to your lover's heart

Using the heart rate monitor built into the Watch's activity sensors, it can measure your heartbeat and send it on to another user's watch.

The recipient will be sent an image, sound and a gentle throb to represent your beating heart.

Romantic, right?

Act as a TV remote

If you are linked up with Apple TV, you'll never have to worry about losing the remote again.

Your Watch can perform the same tasks using its Remote app, and can even turn home theatre devices on and off.

Get one over your mates

In newer series, the Watch's built-in fitness feature allows you to track your progress against a friend's.

By turning on Activity Sharing, you'll be able to see how you match up to your friend's fitness goals, and see when they complete a workout.

Dive down to 50 metres

Start getting used to the idea that it is OK to get your electronic devices wet, as Apple is moving more towards entirely waterproof technology.

In fact Series 2 of the Apple Watch is the first piece of Apple kit that can be submerged underwater up to a depth of 50 metres - so there's no need to leave it by the side of the pool when you go for your morning swim.

Write your name

The watchOS 3 update included the Scribble feature, which allows users to write messages with their finger and send them to their contacts.

This proves very handy when you need to send a message but don't fancy speaking into your watch special-agent-style.

Talk to Siri

Siri can be activated by simply saying "Hey Siri" into your Watch.

Just like on the phone, Siri can handle a number of tasks, from searching for pictures to finding you store locations.

Unlock your computer

If you have a Mac with recent software updates, you can unlock your screen without needing to type your password.

You simply need to go into your computer's System Preferences, select Security and Privacy, and then tick the box that says "Allow your Apple Watch to unlock your Mac".

As long as you are wearing your watch, whenever you wake your Mac up from sleep mode, you won't need the password anymore.

Order your dinner

Just like your phone, the Apple Watch supports a number of apps that allow you to order food on the go.

Some even allow you to save recent orders or favourite dishes, making it quick and painless to fill your belly faster.

Tickle your sense of direction

While using the Maps app on your Watch, the device can tell if you are going the wrong way, giving you a little buzz each time you are supposed to turn.

Two short buzzes means left, a long stream means right.

You'll never have to wander down the street staring down at your map like a lost tourist again.
