61. 30/30

3030
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.

62. Google Authenticator

This one falls under 'essential' rather than 'amazing'. If you've turned on two-step verification on your Google account, chances are it'll regularly ask for a code. You can get this sent to you via SMS, but it's much less hassle to have Google Authenticator instead provide the numbers to type in.

63. Chrome

Safari's a perfectly decent web browser on the iPhone, but Chrome has a couple of particular advantages. First, the card-like tabbing system (technically unlimited, but Chrome does tend to get a bit crashy if you open /too/ many) is really very nice indeed; secondly, you can send tabs to your iPhone from the desktop version of Chrome.

64. YouTube

Apple binned its own YouTube app from the iPhone, presumably because it hates Google far more than it loves online video. Google's own YouTube app works much as you'd expect, enabling you to search and watch an almost limitless number of cats playing pianos, people moaning about stuff to their web-cams, and more besides.

65. iPlayer Radio

BBC Radio was once shoved into a corner of the iPlayer app, despite the brilliance of 6 Music and Radio 4, but now it has its very own iPlayer Radio app within which to dance, shout and generally assault your ears. There's an EPG, an alarm option, alerts for upcoming shows, BBC podcast integration, and AirPlay.

66. Sums

Although we're fond of PCalc, mentioned elsewhere in this selection of apps, there's something really lovely about Sums. The visual design feels sleek and modern, with a handy tape-style path of totals displayed; even better, operations are performed via gestures. This is a bit weird at first, but it soon becomes second-nature.

67. Cards

You might wag your finger at us for including Cards, given that you use it to design cards that then require you to lay down actual money to send to people. But Cards itself is free, and it's actually quite fun to mess around with. As for the cards you send, they cost three quid, but that includes postage and they're of a very high quality.

68. The Onion

There's often a sense with satirical news site The Onion that you can read the headlines and skip the rest, but it's a frequently funny publication that also manages to make some important points on a regular basis. The iPhone app is free and has a 'shake for news' feature for the lazy and indecisive.

69. Photo Editor by Aviary

Another image editor, but Photo Editor is a good 'un. The interface is clear, and it contains all the tools you'd expect: filters, enhancements, cropping, and the ability to fire that picture of your frothy coffee/amusing dog/current skyline to Flickr, Tumblr, Facebook or Twitter.

70. Gmail

"But Gmail works in Apple Mail," you might say. And this is true, but it works really badly, only making accessible recent messages. By contrast, the Gmail app provides a fuller experience, enabling you to search, thread, star and label items to your heart's content.
