If you're planning a big night out, then the first thing you should reach for is your iPhone. In addition to its basic communication functions, by loading it up with the right apps, it can help you with all aspects of entertainment planning.
It will not only help you round up your mates, but also assist in the complicated matter of finding a mutually agreeable time and date for everyone. It can also help find you somewhere to go and something to do, whether you're looking for a huge night out, something a little more sedate or are just happy to go with the flow and see where you end up.
But its talents don't stop there. When you're out and about, your iPhone can help both to keep you safe and keep you entertained. There are apps to help friends and loved ones know where you are at all times. If the conversation ever reaches a lull - or you need to settle an argument - help is just a couple of taps away. There are even apps that will stop you misbehaving when you've had one too many, and to make sure you're sober enough to text that special someone.
Thanks to the combination of always-on internet connection and GPS location, the iPhone even opens up a whole new world of apps that weren't previously possible. These let you check in to specific locations and earn rewards for loyalty, but they also let you see what your friends are up to and where they recommend going - or even in some cases, find out that they're actually at the very same place as you.
Once you're ready to head home, your iPhone's work is still not done. There are apps to help guide you safely home and make your journey as pain-free as possible. The only thing it can't help you with is your hangover!
Arranging to meet up
The first thing you need for the ultimate night out is some people - ideally ones that you know and like. You could, of course, jump straight into the phone app and start calling, but that all feels a little bit 1990s. It's also not exactly time efficient - you'll have to spend a good five minutes per call on idle chat before you can jump to the actual purpose you're ringing for.
Head over to Messages instead and you can tap out your enquiry and dispense with the pleasantries. Even better, you can send group messages so you can organise a whole bunch of people in one go - and if they're all using iMessage, the texts will be free.
Of course, if you're still friends with people that don't have iPhones, iMessage won't work and it will fall back to text message. Instead, try the cross-handset WhatsApp Messenger (69p). This app lets you send free messages between iPhone, Android, BlackBerry, Windows Phone 7 and even Nokia handsets. What's more, as well as sharing plain old text, you can send your location, which makes meeting up with people that are lost much easier.
If you're only dealing with a couple of people, then keeping track of who's coming is pretty simple - but add more than five and it soon becomes unmanageable. Facebook's Event function makes it easy to keep tabs on who's coming and who's a loser.
While there isn't a way to create a new event in the Facebook (Free) app, if you jump over to Safari you can set one up there. Once that's done, you can go retreat back to the safety of app land and see how popular (or not) your event is as the RSVPs flood in. Of course, this is only an option if all the people you're planning on inviting are on Facebook.
Unfortunately, everyone has a friend that's morally opposed to Facebook and refuses to open an account, and occasionally you have to arrange to meet them. For times like these, calendar requests are the solution. Unless your iPhone calendar account is hosted on Microsoft Exchange, however, you won't be able to send them.
But there is, of course, a third-party app solution, this time in the form of iNvite (Free). Simply fill in the details of the event as you would a normal calendar entry, and then add the email address of each recipient. They can then reply with a yay or nay, and it's easy to see who hasn't responded yet.
In addition to deciding who you want to meet up with, you need to settle on when. Managing just your own diary can be problematic enough, but once you add in other people's erratic schedules, nailing it down to a time and date can be nigh-on impossible.
This is where Doodle for iPhone (£1.99) steps in. It's a free web service designed to make finding a convenient time to meet up really simple. The app is a little on the pricey side, but it's very slick and easy to use. Give the event a name, fill in the details and choose a range of dates and times. Participants can then vote on their preferred one and you can schedule the event safe in the knowledge you took on everyone's input before ignoring it and picking the best time for you.
Finding somewhere to go
You've worked out who's coming and what time everyone needs to get there - the next step is to pick what to do. Whatever it is you fancy, the iPhone has an app (or three) to help you narrow down your choices, whether it's catching a movie, having a meal, seeing the newest bands or even finding new things you've never thought of doing before.
If you're looking for a bite to eat, then the two big players are OpenTable (Free) and toptable (Free). They both let you find restaurants nearby and book a table straight from the app. If you think the results look startlingly similar, then it's because UK-based toptable was purchased by US-owned OpenTable a couple of years ago.
However, there's one very good reason to choose toptable, apart from good ol' British pride - the offers. If you're on the lookout for a deal, hit the Offers tab and you can browse discounts available and put the saving towards a second bottle of Prosecco.
However, if your idea of a three-course meal is a popcorn starter, hotdogs, and pick and mix for pudding washed down with a cup of ice and a dash of Coke, then Flixster (Free) is your ideal date for the evening. It will give you the low down on the latest Hollywood blockbusters and where they're showing nearby, so you can whittle down the choices.
And don't forget if you're an Orange customer, and there's a W in the day of the week, to download the Orange Wednesdays (Free) app. This will get you two-for-one cinema tickets, so you can look like you're splashing out and treating someone when it really isn't costing you any extra.
If live music is more your sort of thing, then SongKick (Free) is the go-to app. It'll keep you up to date on when your favourite artists are touring, and the really clever bit is that it scans your music library so it knows what you like (even your guilty secrets). It'll show you an upcoming lists of gigs nearby and you can then add them to your list and even book tickets.
If you'd rather throw some shapes on the dance floor instead, while an overpaid celebrity hits the play button on a playlist on their iPhone, the confusingly concatenated Clubbillboard (Free) is a club rep in app form. You can browse the featured club nights or drill down by date or location to find the perfect party.
All of the options so far are fine if you know exactly what you want to do, but if you're looking for more of a serendipitous experience, then Layar (Free) will show you what's around you right now, with an added drop of Minority Report. By using the compass and GPS in your iPhone, Layar will overlay information on the camera view, giving you your own personal heads-up display. It's a bit like being the Terminator, except without the total disregard for the sanctity of human life.
You can choose different layers (do you see what they did there?) of information, covering everything from restaurants to Tube stations.
Staying safe and getting home afterwards
So you now have the time and the place, but how do you make sure that nothing untoward happens on your night out?
Well, first thing is to make sure someone knows where you are at all times. You could phone in your location every 20 minutes, but there's a more cutting-edge solution. Google Latitude (Free) lets you share your location with your friends so you can keep track of where they are, and vice versa. It can update your location in the background, so you just need to set it and forget it, and your most trusted friends will know where you are at any given time. You can also easily turn it off, for times when you want to disappear off the grid for a while.
Find My Friends (Free) is Apple's equivalent offering, although for some reason someone dressed the app up in faux-leather cowboy hand-me-downs before sending it out the door. Both apps require a huge degree of trust on both sides, so only share them with people you're happy to know exactly where you are any time of the day or night.
After keeping yourself safe, your next priority should be the expensive slab of glass in your hand. Apple's Find My iPhone (Free) service isn't undefeatable by any means, but it will at least give you a fighting chance of getting your phone back if someone nabs it while you're not looking.
If the worst has happened, use this app on someone else's iPhone to log in with your Apple ID. You can then try to locate the device or send a message to it. If you've got information on it that you don't want others to see, you can even wipe it remotely so that your data can't be accessed.
After a long night out, the one thing you don't want is to find yourself out of cash with no way to get home. With that in mind, CashFinder (£1.99) will find the closest cash machine to your location so you can make sure you're not left penniless. It can even tell you which machines charge a fee, so it could actually pay for itself the first time you use it.
Finally, it'll even lead you straight to the machine in question, either sending directions to the built in Maps application or to a satnav app such as CoPilot or TomTom, if you have one installed your iPhone.
Another essential installation if you're going to be out after dark is a flashlight app to turn your iPhone into a torch. Torch for iPhone 4 & 4S (69p) may be more expensive than the freebie rivals, but it's one of the fastest to start up, which could be a life saver. It turns on the camera LED, so you can easily light your way, and there's even a Morse code button for tapping out distress signals. There's also a handy slide-down cover to stop you turning the light off with accidental screen swipes (any torch app has to switch off the light when you lock the screen or press Home).
Let Me Entertain You
Of course, your iPhone is great at rounding everybody up and getting them to the venue, but its uses on a great night out don't stop there. Firstly there's the panicked realisation that you've forgotten to set Dancing on Ice to record just as you're getting ready to perform you own moves that could outshine the has-been celebrity stock.
Fear not - if you're a Sky+ (Free) or Virgin Media TV Guide (Free) owner, you just need to download the appropriate app, link it up to your online account and you can remotely record to your heart's content. The command will be sent directly to your settop box, so it'll be there for you to watch the next day when you're recovering from the night before.
The smoking ban may have curbed the number of people that hold their lighters in the air at concerts, but just because indoor lighting up is now banned doesn't mean a tradition should die out. The Virtual Zippo Lighter (Free) gives you an impressive representation of a real-world item, but without the danger of burning your fingers. It'll sway realistically in the wind, and you can even customise the look and paint job to make it uniquely yours.
If you find the conversation dries up at any point down the pub, then you can suggest an impromptu singalong session with the Glee Karaoke (Free) app. It provides plenty of tracks in the library to sing along to, but you have to pay for each one with tokens. You get 100 to start with, which is enough for a cheaper song, but after that you need to buy or earn extras to carry on making selections. The best bit, however, is that it includes Auto-Tune, so unless you're particularly bad at singing, this app will make you sound like a chart sensation. Worth the entry price alone.
Another app you should pre-load onto your iPhone ahead of any night out is Wikipedia Mobile (Free). When the point comes when the conversation turns to ridiculous statements made without any basis in fact - like whether Ronnie Hazlehurst, composer of the Last of the Summer Wine theme, also penned S Club 7's seminal 2000 hit Reach (he did not) - you can prove them instantly wrong and prevent any further unnecessary debate. No one will thank you in person, but they'll all secretly be grateful.
There is one big problem with taking an iPhone out with you on a night out - the more you drink, the bigger the temptation to contact someone inappropriate. Exes, secret crushes, old teachers you thought were hot back in the day - people you're only able to communicate safely with when 100% sober.
Textalyzer (69p) to the rescue! This app will prevent you texting a particular contact until you've passed a series of mental and physical tests. Simply flag contacts before you go out, add three reasons why it's not a good idea to text them, and you're good to go. When the urge hits, Textalyzer will then make you perform the tests, while reminding you of the reasons it's not a good idea to contact them in between each one. If you pass the challenges, then you're (probably) sober enough to text. If not, then it's best left for another day.
Finally, if there's any better use of technology than using it to order a takeaway on your way home so it arrives just as you get to your front door, we've yet to see it. The Domino's Pizza (Free) app lets you create your dream pizza by dragging and dropping toppings on the screen, and then you can order it straight from the app, ready for delivery.
Location, location, location-based social networks
With its built-in GPS sensor so it can pinpoint your precise location on the earth, the iPhone has opened up a whole new category of apps that let you share your location with your friends and acquaintances. Because you can't fool the GPS, apps can offer rewards to people that go to a particular place most often.
The current king of the location-based app game is foursquare (Free), which rewards users with badges and mayorships if they check in at locations enough. On the face of it, it's completely pointless, but yet it's also strangely addictive. Turning checking in into a game, so you win or defend the mayorship, makes people do it. It's only when enough people you know are using it that the service actually becomes useful.
If you're out and you want to know where to go next, just check the map and see where most of your friends are congregating. You can also see if people are at the same gig or event as you, which you wouldn't know unless you'd spoken to them specifically about it beforehand. It creates a whole new method of connecting with people, and it's very much about being in the right place at the right time. Facebook lets you check into locations too, and other apps are also adding location features to their roster.
Both Qype (Free) and Yelp (Free) offer user-generated reviews of pubs, clubs and other venues, but they've added check in facilities so you can see who's at the same place as you or nearby.
You can't expect these location services to pay off immediately - if you only know a handful of people on them, then the chances of your paths crossing are minimal. But make checking in at a location when you arrive second nature, add a few people you know (and would be happy to bump into out of the blue) and further down the line it will pay off.
So you've had a great night out, been to some amazing places, had the odd chance encounter and everything has run like clockwork. It's now time to get yourself home, and as you might expect, your iPhone's work is not yet done.
If you're in the capital, you're spoiled for choice for transport apps. If you've made it out of the pub before the last Tube train goes, London Tube by Embark (Free) is a beautifully designed app that will help you navigate the Underground. It's a really helpful app whether you're just visiting the capital for the weekend or are simply too, uh, 'tired' to remember your route home.
Leave it too late and you'll be needing a bus. This inevitably involves waiting in the cold for three clichés to come along at once. Slap the BusMate (69p) app on your iPhone, however, and you can wait in the warm somewhere nearby until your bus arrives. Not only will it tell you where the nearest stop is, but it uses live GPS bus data to work out when your bus will arrive. You can then set a reminder and it will tell you when you need to go to the stop to catch the right bus. No more guess work.
If you're partying in the wide world outside the M25, or just want the fastest way to your bed, then a taxi is often the best option. Instead of trying to flag one down or find a minicab office, get Call a Taxi (£1.49) to do the hard work for you. It'll bring back a list of cab offices closest to where you are, and you can call one straight from the app, so you'll be on your way home in comfort before you know it - hopefully just in time for when your pizza arrives.
