How to use Siri on an Apple Watch

5. Send an SMS

Another essential: sending messages dictated through Siri. Just say 'send a message to ...' and Siri will take you through the rest.

Try it with an email, though, and you'll be prompted to carry on with an iPhone.

6. Unit conversions and your maths homework

Need to do a sum? Or convert a Euro figure into pounds? Siri can handle all of that, no problem.

Any calculations like this are simply shown on-screen. Any currency conversions are handled by Yahoo, so you can be sure you're getting up-to-date rates.

The Apple Watch can also convert different kinds of units, not just currency -- weights, distance, whatever you need.

7. Find the nearest Burger King, and get there

By hooking into the Maps app, you can look for nearby shops, restaurants (any location) with Siri. Just tell her to "find the nearest X" and the Watch will zip over to Maps and find whatever you ask for.

Then tap the screen and you'll be able to get directions, on foot or by car. Remember: you can also use the crown to zoom in and out of the map to get a clearer view of where you are.

We tried finding the nearest Burger King and it worked a treat, but you can also ask for vaguer things like the "nearest pizza place".

8. Launch an app by name

Don't like the fiddly apps menu of the Apple Watch? You can also load up apps using the power of your voice.

Just say "Launch" and then name of an installed app, and the Apple Watch will fire it up.

With the apps menu being one of the less intuitive-feeling parts of the watch, this one can come in surprisingly handy.

9. Look up film reviews on Rotten Tomatoes

One of the Siri features you might not expect is being able to look up the critical reception of movies.

The Apple Watch hooks up with Rotten Tomatoes to let you find out whether a film is pure gold or a flop.

You can't read full reviews on there, but you can see the classic per cent 'freshness' rating of Rotten Tomatoes. This tells you what proportion of pro reviewers gave a film a rating of 6/10 or higher. That's what the site classifies as a positive review.

To look up this info, just ask Siri "what were the reviews like for film X". It'll need to get the movie name right to avoid ending up baffled, so make sure you speak clearly.
