Ask Different is a question and answer site for power users of Apple hardware and software. It's 100% free, no registration required.

What are your "must-have" iPhone or iPod touch apps—the ones you can't live without? (Figuratively speaking, I hope.) Please omit apps that come pre-installed.

Rules

  • One app per answer.
  • Use this format for the first two lines of your answer:
    ## [app name](link to website)
    [App Store](link to appstore)
  • Include short description.
  • Check for duplicates before adding new answers.
  • If you find a duplicate, vote it down and encourage its poster to upvote the original entry instead (and remove the dupe).

Please exclude iPad-only apps from here; there's Great iPad Apps for those.

Disclaimer: I know this type of question is controversial. However, great many people do find that properly implemented and curated CW polls can be useful. (If you are one of those who do not, could you simply consider ignoring this?)

Why do people insist on downvoting in these types of questions. That's really in poor taste, I think. If you don't like something, just leave it alone. –  Philip Regan Aug 31 '10 at 20:39

Hmm.. the price probably depends on the Apple store (e.g. for me prices show in Euros) Which price should we note? –  Juan A. Navarro Aug 31 '10 at 20:56

Cheaper alternatives exist, but I haven't regretted buying Things (having used it for almost 2 years). I like the simple yet powerful UI. –  Jonik Aug 27 '10 at 9:52

Facebook

App Store

If you're into Facebook, their official iPhone app is pretty good for staying connected with people.

Reeder is truly what an RSS reader should be. I wish I could find a desktop counterpart that matched it. –  Bryson Sep 15 '10 at 22:28

@Bryson there's Reeder for Mac. madeatgloria.com/brewery/silvio/reeder –  Eugene Bujak Feb 21 '11 at 11:14

Twitter

App Store

The official Twitter client. Previously known as Tweetie 2.

Server Remote

App Store ($3.99)

Simple app to monitor servers, including uptime, running commands, load levels, and memory. Really worth it.

share|improve this answer

OmniFocus

App Store

Task management application that uses the Getting Things Done (GTD) organizational method. Also available for Mac and iPad.

share|improve this answer

Remote

App Store

Wifi remote control for iTunes music library (or Apple TV). This is made by Apple but doesn't come pre-installed.

(Some have pointed out that Remote's development has stagnated, but personally I don't mind that much, as the app works as great as ever, and all major features are already there.)

Safety Light

When it comes to flashlight apps, you get what you pay for. I've tried a number of these, and the interface and technical capabilities are just right. Much, much better than the free ones. Also, it somehow manages to get the screen super-bright, lighting up an entire room without draining the battery like the new LED-using apps that have flooded the App Store. No battery warning to is this one.

share|improve this answer

Simplenote

Note-taking in a better interface than the default Notes application (no Marker Felt) and notes are synched to a server for easy backups and viewing elsewhere.

This is awesome. There's an OS X app called Notational Velocity (that's also open source) that also syncs with Simplenote, and can be set to store notes in my Dropbox. This keeps my notes backed up locally, in the cloud, and in Simplenote's server as well as being editable across any platform. Such a great app/service. –  Bryson Jun 3 '11 at 17:33

Byline

App Store ($4.99 / 3.99 €)
App Store (Byline Free) (free; with ads)

Google Reader on the go. Byline will automatically bring you new content, putting thousands of RSS and Atom feeds at your fingertips. Even when you have no internet connection, Byline gives you instant access to complete web pages. It automatically analyses your feeds so that it can cache the ones with truncated content. This means all your news is there in full when you’re offline, and blazing fast to load when you’re online to boot.

Is this better than the official Wikipedia app? –  mipadi Sep 27 '10 at 16:36

I would say yes, but this of course is subjective. –  Marc Sep 29 '10 at 9:17

Pulse

App Store

Reeder is the best RSS reader for Google Reader. But Pulse is much nicer to randomly read various feeds.

Prizmo for iPhone

App Store ($9.99)

Though it is expensive (compared to other apps that is), this is OCR done right. Works great to capture some texts, quicker than using a scanner and can also be used to import business cards.

StreamToMe

App Store ($2.99)

Streams almost any video or music from your Mac or PC to the iPhone and iPad. The Mac/PC is converting the source file on the fly. Playback generally starts after 5 seconds.

share|improve this answer

Shazam

App Store

Records a few seconds of what you're currently listening to and then shows you information about this song. Shazam is quite old by now, but still an amazing piece of software that's always useful from time to time.

share|improve this answer

Colorendar

($0.99)

Simple calendar app that let's you create a "color diary." Also shows you phases of the moon.

share|improve this answer

OPlayer

App Store (€2,39)
App Store, Lite version (Free)

Plays almost every kind of video format, without having to transcode first. Transfer via iTunes sync or stream right from a web server. There's also an iPad version.

share|improve this answer

ComicBookLover

App Store (free)

Read .cbr and .cbz format comic books. All sorts of transfer options, including iTunes sync. Good, intuitive page flipping. Great in combination with the desktop version, which allows you to add all sorts of metadata to maintain your collection.

Works best on the iPhone's 4 retina display - no need to zoom!

Profanity

App Store ($0.99 / £0.59)

The best (and only) profanity generator in the App store. Always useful in the pub. Otherwise completely pointless but great fun.

Dictionary.com

App Store

Comprehensive, yet free, dictionary & thesaurus. Key features:

  • All word definitions come with the app—no internet connection needed
  • Decent UI with autocomplete (no need to type in the whole word)
  • Audio pronunciations (internet connection required for this)
share|improve this answer

Echofon

App Store (free)
App Store ($4.99)

A great twitter client with synchronization between the desktop version for Mac and the Firefox extension

@Jonik: It's just designed much better and easier to read tweets. You can click links without having to click the tweet and loading it first. Plus on the trending topics you can see explanations, which I like. –  DisgruntledGoat Dec 16 '10 at 15:10

Pocket

App Store

Pocket lets you save webpages to read later, even without an internet connection. Ideal for those who have iPod touch but don't have access to Wifi. Also while travelling in subway, where 3g always goes haywire.

share|improve this answer

Doodle Jump

App Store

Doodle Jump™ is THE MOST ADDICTIVE GAME on the App Store. Enough said :)

share|improve this answer

Prowl

App Store ($2.99)

The app itself is ultimately a "dumb client" for sending push notifications to your phone. Prowl is a service used to push arbitrary text to you. There are numerous services in the wild for leveraging it to send you NAGIOS and other alerts from monitoring software, Prey Fetcher exists to push posts, @'s, DMs, and list updates to you, and anything else you're capable of dreaming up.

Spotify

App Store

For listening to music off the internet (directly on wifi/3G or via offline playlists).

NB: Spotify is only available in certain countries, and Spotify Premium (€9.99 or £9.99 per month) is needed to use the iPhone app.

Now with iOS 4 + iPhone 4 (unlike with my unjailbroken iPhone 3G earlier) the experience is really good, as you get background play and ability to use normal iPod playback controls (e.g. the headphone remote). In other words, it's similar to using the built-in iPod app, except that you have approximately 10 million tracks available at your fingertips.
