Comics
Comics, Dropbox and eBay

26. Comics

In all honesty, Comics is a little awkward compared to using it on an iPad, but you won't find a better comics experience on an iPhone. The app is free, as are dozens of downloadable comics - and once you run out of those, many more are available to buy. Reading works on a frame-by-frame automated 'zoom' basis, and is surprisingly usable.

27. Dropbox

Plenty of apps exist for transferring content between your computer and your device, but Dropbox is free and easier to use than most of its contemporaries. Dump files you want to sync in a folder on your computer and Dropbox for your device will enable you to access them, download them for offline viewing, and, in many cases, view them.

28. eBay

On using the eBay app, there's a good chance you won't go near the eBay website again. The app is fast, has great saved searches (which flag new finds), and enables you to create listings. The last of those things is also improved by the built-in bar-code scanning.

Evernote
Evernote, Facebook and FindMyiPhone

29. Evernote

Clients to access the popular Evernote service for storing notes and ideas online are available for so many platforms that we half expect a ZX Spectrum app to be announced tomorrow. On the iPhone, Evernote is efficient and usable, enabling you to rapidly scan your notes and also create new ones.

30. Facebook

The world's biggest social network brings a tightly honed experience to the iPhone and iPod touch, but nonetheless still enables you to access your contacts, feeds and other important information. This sense of focus makes it in many ways superior to using Facebook in a desktop browser.

31. Find My iPhone

For the paranoid souls out there (or the unlucky ones who've had their devices pilfered), Find My iPhone is a must-have download. Assuming you've a 2010 or later iOS device, you can set up a free account and locate your devices within seconds. (Note that older devices can also be added to Find My iPhone - you just need a recent one to get things going.)

GarageBand
GarageBand - now free for iPhone

32. GarageBand

Apple's GarageBand turns your iPhone into a recording studio. Previously a paid app, GarageBand now has a freemium model. For no charge, you get full access to its features, including a range of smart instruments, MIDI editing and song arrangement. The only limitation is that relatively few instruments are included, but more are available via IAP.

Google Maps
Google Maps, Google Translate and Groove

33. Google Maps

When Apple removed Google's data from its Maps app, seemingly half the internet went nuts. In hindsight, the decision has been beneficial, because it resulted in Google creating its own mapping app, Google Maps. Bar some mildly irritating signing-in nonsense, this is a first-rate application - the interface is straightforward, the mapping is accurate, and it's also a means of getting Street View back on to your iPhone.

34. Google Translate

Assuming you're online, Google Translate is a great app for translating text between dozens of different languages; handily, the most popular of them enable you to speak into your device and listen to translations. It's also considerably cheaper and more portable than dozens of translation staff.

35. Groove

If you've a large music collection, it can sometimes be difficult to decide what to listen to next. Groove tries to figure out your listening habits and cross-references your collection with Last.fm data. The result is constantly evolving automatic personalised playlists that might just change your iPhone music-listening habits for good.

Instagram
Instagram, iPlayer and Kindle

36. Instagram

Take a photo, smash a filter into it, and upload it. Instagram's service is now used by millions of people to share nuggets of visual loveliness, and the app itself is a pleasure to use, and also to browse during moments when you're not feeling quite so inspired.

37. iPlayer

Watch live TV and browse featured and recent BBC shows in the BBC iPlayer app. There's a favourites section to get easier access to your top shows, and AirPlay support for firing footage at your Apple TV. (This uses the system AirPlay functionality - start playing a show, double-click the Home button, swipe right twice, then choose 'Apple TV' from the AirPlay button.)

38. Kindle

With iBooks on the iPhone, you might wonder why you should bother with Amazon's Kindle. After all, the app's not as pretty as iBooks, nor is there an integrated store (you buy in Safari and sync purchases to the app). However, Kindle offers a massive selection of books compared to Apple's app and the reading experience is great.

Movies
Movies by Flixter, Netflix and Pocket

39. Movies by Flixter

Although some aspects of cinema listings app Movies by Flixter are disappointingly US-centric (notably regarding details on upcoming movies and DVDs), it succeeds where it matters. Select a film and the app figures out where you're located, lists nearby cinemas, and displays times your chosen film is showing. Efficiency can be further increased by pinning favourite cinemas to the top of the list.

40. Netflix

Brits might rightly grumble that the Netflix selection leaves a little to be desired, but it's still a very affordable way to get a ton of TV in front of your eyes. The app works much like you'd expect: browse, watch, realise it's three in the morning - again.

41. Pocket

The service formerly known as Read It Later enables you to save pages from websites, to read them later, bereft of the advertising and other junk on the original page. The service is free, as is the Pocket app, which downloads your articles, so that you can digest them without a web connection.

Remote
Remote, RunKeeper and Shazam

42. Remote

The remote for Apple TV is a bit of a joke when you need to do anything more than play or pause. Remote is a free app which provides much better control and the ability to stop yourself going mad when typing things into search fields. It'll also happily use Home Sharing to pull content from computers on your network to your device, or fire said content at your Apple TV using AirPlay.

43. RunKeeper

The prospect of Nike+ but better and for free might sound unlikely, but that's what RunKeeper provides. Previously split into 'pro' and 'free' versions, the developer now generously includes all the features in one free app.

That means you can spend no money, yet use your iPhone's GPS capabilities to track your jogging and cycling routes, and examine mapping and details of your pace and calories burned. Activities can be shared online, and treadmill runs and other exercise details can be entered manually.

44. Shazam

Shazam is an app that feels like magic when you first use it. It's deceptively simple—hold your iPhone near to a music source, and wait while the app listens and tells you what track is playing. But the sheer technology behind this simplicity is mind-boggling, and while Shazam doesn't always guess right, it's worth a download.

Skype
Skype, TED and 30/30

45. Skype

FaceTime is a great alternative to standard voice calls, but it's no good if you're trying to contact someone without a Mac or compatible iOS device. Therefore, Skype remains an essential download. The interface is simple and usable, enabling anyone with a Skype account to make free calls to other Skype users and cheap calls to anywhere in the world. If you're on Pay and Go, this is particularly handy, but the app also enables iPod touch users to utilise their devices for calls.

46. TED

TED is brain food. The app provides access to talks by insanely clever people, opening your mind to new and radical ideas. You can also save your favourite talks locally, for even easier access, or ask the app to inspire you, based on your mood and available time.

47. 30/30

Timers and task managers are usually designed with extreme efficiency, to the point they practically yell NO FUN ALLOWED in your face. 30/30, however, provides a streamlined, tactile interface that happens to look great, is fun to use, and that makes it a breeze to create lists and define timers. It also enables looping for anyone addicted to the Pomodoro Technique.

TuneIn
TuneIn, Twitter and Wikipanion

48. Twitter

The official Twitter app might lack some of the features found in the likes of Tweetbot, but it does provide a sleek and simple means of using the service. It also rapidly rolls in new features from the website, such as the Connect and Discover views, along with expandable tweets that contain photos and videos.

49. TuneIn Radio

Don't bother buying a DAB radio - just install TuneIn Radio instead and plug your device into a set of speakers. TuneIn Radio has a great interface for accessing over 50,000 digital stations; it also has AirPlay support, and you can use it as an alarm clock.

50. Wikipanion

The Wikipedia website works fine on iPhones, but a dedicated app is a better bet. Wikipanion is a freebie which gives you quick access to article sections, in-article search, viewing options, bookmarking, and the ability to tweet about whatever odd fact you've just unearthed. Also, wonderfully, there are no ads.
