Introduction
The iPhone 6, 6 Plus, and iOS 8 represent tremendous
opportunities for mobile apps. At Appsotrophic, we’re excited
to help you explore the possibilities.
According to Apple CEO Tim Cook, Apple’s recent release of the iPhone 6, the
iPhone 6 Plus, and iOS 8 represents "the next chapter in Apple's story.” Launch
sales of the iPhone 6 and 6 Plus soared to a record-breaking 10 million+, the
iPhone 6 Plus sold out, and both of the new iPhones received rave reviews.
In this white paper, we explore the most important and exciting updates for the
iPhone 6, 6 Plus, and iOS 8.
Whether you have an app to update, or are planning a new one now, Appostrophic
can help you dive into mobile innovation.

New Screen Sizes
Why you need to modify your designs to accommodate
the larger iPhone screens?
The iPhone 6 screen is an increase in real estate over the current generation of
iPhones. With such massive screens, you have the opportunity to make your
content more beautiful and to enable your user to do more, faster.
The UI elements are spaced out more comfortably, easier to interact with, and
have more area for content. As a result, it’s important to consider how content in
your app is represented.
Questions to Ask
1. Does your app content have enough value? Does visual placement reflect this?
2. Is your app using the new screen real estate effectively?
3. Should you consider enlarging or modifying your content?
4. Should you modify your UI controls to benefit users?

Sensors
How 4 new sensors - M8, HealthKit, NFC and the Barometer -
can lead to hundreds of new features
Barometer
This allows us to measure the device’s altitude
above sea level. Although the most straightforward
uses will be in sports/fitness apps, there are
creative opportunities.
Ideas for Use
For fitness enthusiasts—especially for hikers,
bikers, or mountain climbers—the barometer can
be useful to detect changes in elevation and air
pressure and provide accurate weather
information.
NFC
Near-Field Communication is essentially the
foundation of the upcoming Apple Pay platform.
Looking at how Apple has introduced similar features
in the past, it is reasonable to assume that with iOS
8, developers will get access to the NFC chip.
Ideas for Use
For now, Near-Field Communication is just being
used for Apple Pay’s mobile payments, but in the
future it can have a myriad of uses, such as pairing
devices or sharing files.

Sensors
HealthKit
HealthKit API combined with the M8
motion coprocessor, developers can build
apps that utilize and exchange a plethora
of health-related data.
Ideas for Use
Tracking daily nutrition information, sleep
length and quality, and exercise is simple
with the HealthKit API. Information can be
pulled from any fitness or health app of
your choosing and be stored in one
centralized location.
M8
M8 motion coprocessor allows for more
accurate and energy efficient motion
tracking with additions like a barometer,
gyroscope, and accelerometer.
Ideas for Use
Activity tracking apps like Argus or Nike+
can track your steps and tell the
difference between running vs. riding a
bike. The improved M8 motion
coprocessor has its own dedicated CPU
(central processing unit) which uses less
battery power. What motions could your
app benefit from tracking?

New APIs
5 of the coolest new APIs (out of 4,000+ available) to consid-
er for your app
Touch ID
This fingerprint-based authentication method introduced with iPhone 5S is finally
available for third party developers.
Ideas for Use
Touch ID has many potential and massively useful applications, such as one-touch
Amazon and PayPal purchases.
HomeKit
A foundation for a centralized platform which allows iOS devices to control
supported home devices and appliances.
Ideas for Use
For example, Nest thermostats are controlled through HomeKit. Third party tools
may also use Siri to control a smart home’s lights, locks, and temperature settings.

New APIs
Continuity
Perhaps the best proof of Apple’s dedication to seamless user experience,
Continuity is designed to allow users to switch between devices and painlessly
pick up their workflow where they left off. Documents, settings and features are
seamlessly carried over, allowing users to continue their work without disruptions.
Ideas for Use
Apple’s goal of interconnecting devices is admirable, especially if your products
are present on multiple platforms. If you start typing an email on your laptop, you
can switch to your iPhone and continue writing it.

New APIs
Camera
Developers gain a much deeper integration with the iPhone’s cameras. You will be
able to build much more precise and professional-grade photo and video editing
tools. Combined with the hugely improved camera hardware and the new large
screens, suddenly the iPhone becomes a viable semi-pro photo editing platform
Ideas for Use
You can adjust all the usual manual controls, such as shutter speed, exposure,
and filters, without leaving the app you’re using.

New APIs
Gaming
Developers should be aware of SpriteKit, SceneKit and Metal: three new
frameworks which enable deeper integration with device hardware, better tools for
meeting gaming-specific requirements, as well as much more refined visual and
physics-based effects.
Ideas for Use
Even if you don’t have a game app, these API’s can also improve the
responsiveness of your graphics processing unit (GPU) and the potential of your
photography, video, and audio.

Interactive Notiﬁcations
Better Connect With Users with Actionable Notifications
Prior to the release of iOS 8, Apple’s push notifications were simple messages
that occasionally popped up, informing you of a Facebook message, for
example, or inviting you back to a game you hadn’t played in a while.
Although push notifications are reasonably successful for app marketers—one
study showed a 278% increase in ecommerce app launches in phones with app
notifications enabled—acting on them required a user to launch an app, quitting
whatever they were currently doing in the process. Because of this, many iPhone
users found the alerts intrusive and disabled them altogether.
Actionable notifications, however, solve the
app switching problem by allowing users
to interact with an app within the
notification. Each notification, whether it’s
displayed in the Lock Screen, Notification
Center, or as a pop up banner, can offer
users specific actions they can take
immediately – without leaving what they’re
currently doing.
As a result, iOS 8 users can now take
actions such as commenting on Facebook
or making a purchase without needing to
cycle between apps.
Idea in Use
The new functionality of actionable
notifications should go a long way in
reducing the annoyance of pop up
notifications and, in turn, the number of
users who disable them. They’re now
excellent tools for retargeting and
engaging with your users.

Widgets
Stay Top of Mind with Widgets
Arguably one of the biggest changes to iOS 8 is the introduction of widgets.
Already popular on Android, widgets allow any app to display information and
limited functionality in the notification center (think of the existing weather and
stock widgets).
For example, widgets can bring users the latest news or sports scores, or invite
them to interact with an app or accept an invitation
Ideas for Use
The key to success with widgets is striking
the right balance. You want to offer users
the convenience of easier access to
relevant information while at the same time
enticing them to further interact with your
app.
Like actionable notifications, widgets
should be thought of as means to further
engage with your user base and remain
top-of-mind. They won’t necessarily help
you bring in new users, but they can help
you retain the ones you have, which is a
real benefit in an increasingly competitive
app environment.
