The Rise and Rise of Mobile Phones

A while ago, a software developer friend told me about a PC fighter plane game he was working on. He was literally spending thousands of hours researching game engines, polishing scenarios, making the graphics as realistic as possible.

So I decided to help him with a demonstration.

Next time we were out with some other friends, I asked everyone “What was the last PC software package you bought?”.

Everyone looked at me blankly.

Then I asked “What is your favourite mobile phone app?”

Everyone pulled out their mobile phones and started talking at the same time.

My software developer friend leaned forward quietly and said “you b*stard” – but he took my point.

Last I heard he had converted all his software to run on a mobile game engine, and was busy making it all look good for a mobile environment.

PCs still have their uses – as Steve Jobs, the legendary ex-CEO of Apple once said, a PC is good for content creation. I usually use a Mac laptop to create new entries for this blog.

But mobile devices – phones, iPads, tablets – have come to utterly dominate content consumption.

Next time you think up a great idea for a PC application, take the thought a little further, and consider how your idea would work in a mobile phone environment. Because the chances are it would work well – and Mobile is where the action is.

The New iPhone – What You Need to Know

Time to review your apps – Apple has officially announced two new iPhones – the iPhone 5S, and the more budget oriented iPhone 5C.

Both phones will run iOS 7, and iOS 7 will shortly be offered to existing phones – which could potentially break existing apps.

A new mobile operating system is an exciting opportunity to offer new products and services – but for mobile app development, it also presents risks to the stability of existing mobile apps.

While Apple operating systems are highly compatible with each other, every new version of the operating system comes with new rules, new ways of doing things. Sometimes these new rules break existing apps, often in subtle ways.
The key areas to watch in iOS 7 apps appear to be further tightening of the rules regarding access to iPhone contacts, and changes to how apps access internal identifiers.

While most of the pain of changes to address book access occurred with the upgrade to iOS 6, there are still likely to be apps caught out by the iOS 7 rule changes.

Similarly, a number of games will potentially be affected by the internal identifier rule change. In iOS 7, Apple have removed access to an API which a lot of game developers use, to uniquely identify a device – especially with multiplayer games. So quite a few games will simply break when the phone or iPad is updated to iOS 7.

There are also changes to screen layout rules, which might catch a few apps.

My advice – make sure your developer is available, to help you if you hit problems. If you are especially worried, for example if you have a profitable app which you want to protect, your developer can assist you with testing your app using a pre-release version of iOS 7, to minimise the risk of embarrassing failures when people try to use your app on an upgraded phone.

If you have any questions about how the imminent shift to iOS 7 might affect your app(s), please leave a comment, or contact me for more information.

A Deep Linked Facebook Mobile App

I recently released RubyApp, a deep linked Facebook App.

RubyApp allows users to send a bouquet of pictures, and a short love message. You can tag the recipient of your message (which prompts the recipient that they have been tagged), make the message public, or both.

Facebook Deep Linking is a feature provided by Facebook to make your mobile app an extension of the Facebook experience. When a user clicks a Facebook news feed message associated with the deep linked app, instead of opening a website, Facebook opens the mobile app, and passes information about the clicked message to the mobile app, so the mobile app can immediately present the media associated with the message.

If the deep linked mobile app is not yet installed, Facebook prompts the user to install the app.

As you can imagine, this is a terrific way of driving viral mobile app installation – people see a Facebook post which interests them, click the post, and painlessly download and install yet another copy of your app. They then use the app to post their own media, which all their friends can see – and so on.

And this is exactly what is happening with RubyApp. A few people tried the app, loved it, and it is now spreading throughout the Facebook community – with no publicity effort from me whatsoever.

What happens if a user is not using an iOS device? For them, there is the RubyApp website – https://apps.facebook.com/ruby__app/.

Why build a deep linked Facebook mobile app, if you already have a Facebook website? The rationale for building a deep linked Facebook mobile app was that I wanted to include a soundtrack with the bouquet of pictures. iPhones do not automatically play sounds presented by websites – so the solution to creating a high quality user experience for iPhone and iPad users was to bypass this limitation, by creating RubyApp.

Apple iWatch Delayed?

The Register printed an interesting article today, suggesting that the Apple iWatch will be delayed, citing as evidence Apple’s aggressive iWatch team hiring spree.

What does iWatch mean for app development?

When the iWatch arrives, it will present an entirely new vector of customer requirements. Assuming Apple opens iWatch to developers (and there is no reason to think they won’t), iWatch will be an opportunity to give prominence to your offerings. If your competition only has a phone app, the iWatch presents a few seconds convenience – if consumers choose your app, they save a few seconds of their life, by engaging with your app on their iWatch, rather than having to pull their phone out of their pocket.

Do a few seconds matter?

The answer is an unequivocal YES. The world’s premier search engine, Google, have calculated that improving response times by just a tenth of a second produces a measurable change in customer behaviour.


Average increases in response time of only a tenth of a second have a negative effect on search usage.

The downside is what works on a phone is unlikely to work, unchanged, on a watch size display. No rework was necessary when iPad Mini was released, because iPad apps worked, without modification, on the iPad Mini platform. But a watch size device will be not be able to display content designed for a phone size display. In addition, a watch size device is likely to be heavily constrained, in terms of processing power and battery life, even when compared to a phone.

so watch apps will be new. They will be lean, mean and clean – apps cut back to the bare essentials. But in terms of user interaction, a good watch app will be first in the queue – people will use their watch, if it saves them pulling out their phone. When iWatch is released, getting in first with apps which fulfil user’s needs will be your key to beating the competition.

The Third Dimension

When will my phone produce true 3d images – images with depth, like a 3d Television?

The answer – phone size 3d devices are already appearing.

Wikipedia provides a list of 3d phones which are already, or soon will be on sale. My experience with such phones is current generation 3d phones are power hogs – if you want to play a 3d game, you need to plug the phone charger in, otherwise the 3d display will flatten your battery in minutes.

Normal phone displays are power hungry. If you stop touching the phone, normal 2d phones dim the backlight within a minute or two, and switch it off completely a few minutes later, to preserve battery life.

The reason 3d displays are so power hungry is that 3d displays produce two display images – one for each eye. So a 3d phone consumes battery reserves at least twice as fast as a normal 2d phone – even faster once you include the additional computation required to keep both displays coordinated.

What we are looking for then, is not a new type of display – 3d displays are already available. What we need, to make 3d displays practical, is a leap forward in mobile battery technology.

There is good news – we probably won’t have long to wait. And when true 3d displays become mainstream, most of the games and apps constructed by developers like me will be able to use the new technology, without modification.

Under the hood, games and other advanced apps are already 3d. When you see photo realistic space ships, monsters, or other 3d components of app games, what you are seeing is actually a computerised 3d shape created by app developers and artists, projected by software onto a 2d display. No tricks – phone apps and game consoles are already 3d under the hood.

Will the next iPhone, iPhone 6, be true 3d? Probably not. But my prediction is iPhone 7 might be.
