iOS 8 is the eighth major release of the iOS mobile operating system designed by Apple Inc. as the successor to iOS 7. It was announced at the company's Worldwide Developers Conference (WWDC) 2014 on June 2, 2014, and was released on September 17, 2014.[2] Billed as "The biggest change to iOS since the introduction of the App Store", iOS 8 builds on the major redesign that iOS 7 introduced, while including many enhancements and interface improvements. As of April 13, 2015, iOS 8 has been installed on 79% of compatible Apple devices.[3] The latest version of the operating system is iOS 8.3, released on April 8, 2015. iOS 8.4 beta 1 was released on April 13, 2015.


iOS 8 Beta 1 was introduced at the company's Worldwide Developers Conference on June 2, 2014, and it was released to developers later that day. From then until September, new Beta versions were seeded to developers typically every two weeks. Each new Beta version contained bug fixes and improvements over the last.

On September 9, 2014, at their 'Wish We Could Say More' event, Apple introduced the iPhone 6 and 6 Plus, a new mobile payment service called Apple Pay, and the Apple Watch. At their event, Apple also announced that iOS 8 would see a public release on September 17. The Golden Master version was seeded to developers shortly after.[4][5]

On October 16, 2014 at their "It's been way too long" event,[6] Apple introduced the iPad Air 2, iPad mini 3, new Mac mini and the iMac with Retina 5K display. At the event, Apple also announced that iOS 8.1 would see a release of October 20. iOS 8.1 saw the return of the camera roll, the introduction of Apple Pay and bug fixes.[7]

On November 17, 2014, at the release of iOS 8.1.1, Apple updated the iOS App Store so that all apps for which there is no charge to download are labeled "GET" instead of "FREE".

On March 9, 2015 at their "Spring Forward" event, Apple announced that iOS 8.2, which includes support for the Apple Watch. It was released to the public within a few hours. Many new products were announced at the event, including the brand new MacBook plus the prices and release date for the Apple Watch.

On March 12, 2015, Apple seeded iOS 8.3 beta 3 to developers. A new iOS public beta program was also announced, allowing members of the public to download and test iOS 8.3 beta.

On April 13, 2015, Apple seeded iOS 8.4 beta 1 to developers, featuring a redesigned Music app.


Photos and Camera[edit]

The Photos app contains more options to edit photos. The cropping feature now enables rotating images both clockwise and counter-clockwise. Furthermore, users can set the desired brightness and colors for photos. In iOS 8.0, the Camera Roll and My Photo Stream albums were removed; they were brought back in iOS 8.1. The Camera app now features a shot timer for the front camera, which can be set to 3 or 10 seconds. The camera also has a new time-lapse mode.

Notification Center[edit]

Notification Center has been redesigned. In the iOS 8 Notification Center, there are two tabs, (Today and Notifications), whereas the Notification Center in iOS 7 had three tabs (Today, All, and Missed). Users can now add or remove widgets in Notification Center with the "Edit" button located at the bottom. This also allows the rearrangement of notification widgets. The "Clear" button that is used to clear notifications, has been tweaked to make it slightly more visible. Users are also now able to reply to text messages directly from the Notification Center instead.


In the Messages app, users can send audio and video messages by holding down the record button. In group conversations, users can add or remove someone from a thread, name a thread, share their location in a thread, view all attachments, and turn on Do Not Disturb to not receive notifications from a specific thread. Users can also set messages to auto delete after 30 days or a year.[8]


iOS 8 includes a new predictive typing feature called QuickType. It displays word selections above the keyboard as one types. The feature can be turned off in Settings, or hidden using a swipe gesture. Additionally, iOS 8 allows users to install third-party keyboards.[9] Many developers have ported their keyboards to iOS, including Minuum, Swype, SwiftKey, Fleksy and Adaptxt.[10][11]

Family Sharing[edit]

New to iOS 8, a user can add five others as family members. Family members can share purchased apps, music, movies, TV shows, and books using the same credit card. iOS 8 can also automatically set up photo streams for all family members. Calendars may be synced between all members. Family members can share their location with other family members.[12][13] You can send iTunes download requests to another accounts for approval through Ask to Buy as long as you are signed up as a child.[14]

iCloud Drive[edit]

Main article: iCloud Drive

iCloud Drive is Apple's file hosting service for devices running iOS 8 or OS X Yosemite. This feature allows users to save photos, videos, documents (Keynote, Pages, and Numbers), and music, and other apps' data to iCloud. Users can start their work on one device and continue on another device.[15] By default, users will get 5 gigabytes of storage for free, but this space will be expandable via subscription.


Main article: Health (application)

HealthKit is a service that allows developers to make software that integrates with the new Health application. This application allows users to track their steps, oxygen, sleep levels, and other health related data. Additionally, users can enter their medical history, so that the application can help serve them better.[16] In a commercial for the iPhone 5S, the exercise song Chicken Fat is used to promote the new service.[17] The Healthkit application is available on iPhone 4s or later and in iPod 5th generation.[18]


HomeKit is a database similar to HealthKit and PassKit[19] that allows developers to make software that discovers, configures, communicates with and controls devices for home automation. Actions can be grouped together and can be initiated using Siri[20] either when you are at home or if you have AppleTV, from elsewhere .

There are also the option for manufacturers of existing equipment to make gateways that connect equipment using their protocols to Homekit, one of the first to do this is Insteon[21]


A set of tools that were present across OS X Yosemite and iOS 8 were named Continuity. The most popular one of them all is named Handoff.

Handoff allows users to share documents, e-mails, and websites over Wi-Fi or personal hotspot between iOS 8 and OS X Yosemite devices.[22] Handoff also allows all text messages to be read and replied on their Mac and iPad. This also is extended to the uses of the voice function to make and receive call on their Mac and iPad if their iPhone is connected with iCloud.

This feature is supported only by compatible Macs with Bluetooth LE running OS X Yosemite, and by compatible devices running iOS 8. The following devices running iOS 8 will be supported: iPhone 5 or later, iPad (4th generation) or later, all iPad Mini models, and iPod touch (5th generation).[23]


In iOS 8, Spotlight is integrated with a number of web services so that users can search using Wikipedia, Bing, or Google. Other services include: news, nearby places, suggested websites, movie showtimes, and content that is not already on the device from the iTunes Store. Moreover, the enhanced spotlight search is also available in safari browser, so you can have now your own search engine that will find your desired stuff on services linked to spotlight search.[24][25][26][27]

Other updates[edit]

The multitasking screen now shows a list of recently called and favorited contacts, which can be turned off in Settings.

EU Internet has been added in the cellular settings to allow data roaming within the European Union only.[28]

Siri now outputs what users say as they speak for more accuracy and has integrated Shazam support. Holding down the home button will activate Siri, and saying "What's playing?" will identify what song is playing.[citation needed] Saying "Hey, Siri" whenever the device is plugged into a power source will activate Siri if the feature is turned on. Purchasing content through Siri is now possible, and Siri now has support for 22 new languages.

Wi-Fi calling has been added to allow mobile phone calls over Wi-Fi. It is planned to be available for customers of EE in the UK.[29] AT&T[30] and Verizon[31] are going to launch Wi-Fi calling in 2015. According to Computerworld, Vodafone might also provide this service to its customers in Australia.[32] Wi-Fi Calling is available to T-Mobile customers in the US.[33]

Apple used the mobile multiplayer online battle arena game Vainglory (Halcyon Fold map pictured) to demonstrate the graphics capabilities of Metal, iOS 8's new graphics API, at the iPhone 6's September 2014 announcement event.[34]


A study by Crittercism found that the rate at which applications crashed in their tests was 3.56% on iOS 8, higher than the 2% found on iOS 7.1.[35]

On September 24, 2014, the iOS 8.0.1 release crippled iPhone 6 and iPhone 6 Plus of Touch ID and cellular.[36] The update was released at 9:00 AM PST, and approximately at 11:00 AM PST, Apple removed the update due to these problems, as well as other minor issues. A day later, Apple released iOS 8.0.2 which contains all the fixes included with iOS 8.0.1 and also fixes the problems that iOS 8.0.1 introduced.[37]

There are unfixed Bluetooth, Wi-Fi, and battery issues. There is still no official statement from Apple about the issues that will be fixed in the future.[38]

On March 9, 2015, the date iOS 8.2 released, many game users mainly from East Asia reported missing characters in their games after upgrading to 8.2. Game manufacturer has no idea about the possible cause, as the characters having problems seems to be arbitrary. The problem was later found to be related to the change of font location, and Unity has got a fix to such problem.[39]

On April 8, 2015, Apple Inc. released iOS 8.3 and on the next day April 9, 2015, hundreds of iPhone and iPad Air 2/iPad mini 3 users are reporting on Apple’s Support communities and Reddit that after upgrading to iOS 8.3, they have completely lost the ability to use Touch ID in the App Store. Instead of prompting them to verify their fingerprint before purchasing or downloading any new app, the App Store now asks users to enter the password of their Apple ID. Even disabling and re-enabling Touch ID for App Store has not solved the issue for the affected users, and at the moment, there does not seem to be any temporary workaround to this problem.


iOS 8 received mixed reviews. Brad Molen of Engadget said, "To be fair, much of the focus on iOS 7 was on getting developers up to speed on the design overhaul; iOS 8, on the other hand, is all about adding functionality to the iPhone and iPad. As a result, you’re not going to see many significant changes to the layout or design of iOS this time around. In fact, you may not even be able to tell the difference between iOS 7 and 8 unless you’re looking closely. But don’t let looks deceive you: There’s a lot of new stuff under the hood."[40] Charles Arthur of The Guardian said, "There’s no radical change in appearance; instead, there are deeper changes, and an overall cleaning up of the interface."[41]

Darrell Etherington of TechCrunch said, "Best for me has been the ability to mute and leave group conversations, which is something I’ve been sorely missing since the introduction of group iMessage conversations. My family can tend to get pretty chatty on these threads, and while that’s generally fun, it can also be a huge distraction during work events, and during other times when I’d appreciate not getting a whole lot of noise mixed in with my signal.[42] Martin Byrant of The Next Web said, "These features won’t set the world alight for everyone, but they work well and they’re nice extras for people who send a lot of iMessages. That’s especially true if you own a Mac as of course messages are synced there too."[43]


In September 2014, a hoax Apple advertisement for an alleged feature called "Wave" of iOS 8 circulated on Twitter. The advertisement promised users that they would be able to recharge their iPhone by heating it in a microwave oven. This feature does not exist, and the media cited numerous people reporting on Twitter that they had destroyed their iPhone by following the procedure described in the advertisement.[44][45]

Version history: Portable iOS devices[edit]

Apple announced iOS 8 on June 2, 2014 at its annual Apple Worldwide Developers Conference (WWDC) event, with release announced for September 17, 2014. With this release, Apple continues the cycle to drop support for older devices. However, unlike past releases, which usually dropped support for two devices, iOS 8 only drops support for one device, the iPhone 4. Supported devices are the iPhone 4S onwards, iPod Touch (5th generation) and all iPad models apart from the first generation: the iPad 2 onwards, and the iPad Mini (1st generation) onwards. The iPad 2 is also the first Apple device to support five major versions of iOS: iOS 4, iOS 5, iOS 6, iOS 7, and iOS 8.

Version history: Apple TV (3rd generation) onwards[edit]

Supported devices[edit]


Since its release, many people have been complaining about the amount of free space iOS requires to install Over the Air. It requires around 5.5 to 6.5 GB of free space for the installation process to complete over-the-air. Once installed, it takes up on average 740 MB more storage on iPhones and iPod touch and 1-2 GB on iPads than iOS 7.[46]

The iOS 8.1.3 update reduced the amount of free space necessary to update a device over-the-air. It requires around 600 MB for iOS 8 users and 3 GB for iOS 7 users to update over-the-air.[47]
