How to make money from app development

Be the next app millionaire
Angry Birds, developed by Finnish company Rovio Mobile, is the most downloaded game on Android Market and Apple's App store

According to the media hype, the new phone app market is like a modern day gold rush.

Headlines like 'Infinity Blade makes $1.6million in five days', 'Make $100,000 a year selling Android apps' and 'Angry Birds makes $2million a month' are enough to make a lot of hobbyist programmers sit up and listen.

Cut the rope

COMPETITIVE MARKET: Cut the Rope was hugely successful, but was eclipsed by Infinity Blade

And here's the crux - half of the apps that make headlines for achieving a million downloads in a matter of days are free. Yes, these people are 'app millionaires', but they won't be seeing a single penny from sales.

Free the adverts

That isn't a problem with foresight. Rovio released a free version of Angry Birds on the Android Market with an advertising bar on it, and the ads are now making the company more per month than the paid-for version - millions of dollars.

This isn't an option for every app, though. This revenue system relies on the amount of time people spend playing Angry Birds - and they play it a lot.

As Rovio spokesperson Ville Heijari told us, "What has been most impressive for us is the estimated 200 million minutes that our users spend on average with the game every day." That's the equivalent of the viewing figures for a small TV channel.

That didn't happen by accident - a great deal of research went into creating Angry Birds. As Heijari said, "Rovio had produced 52 mobile games prior to Angry Birds since 2003, so the core team [already] had a pretty solid experience at developing games."

Rovio specifically concentrated on the retention of users - it didn't want to create an app people would download once then forget about. To help this, every month the Rovio team releases an update for the app (and 80 per cent of people with the game accept that update).

Oddly, these free updates also lead to an increase in new downloads of the app, probably because as the updates encourage people to play it again so new people (users' friends, for example) are exposed to it.

With all this experience and the eight-month development cycle, did Rovio expect the success it got? "When we released the game," said Heijari, "we had a strong gut feeling that we had a hit game in our hands, with the potential for at least 200,000 downloads. So we can honestly say that we did exceed our every expectation."

Rovio may not have expected the response it got, but it quickly turned it to its advantage. Angry Birds is now a brand, and Rovio is examining a whole wealth of possible profit-making spin-offs - keep an eye out for the Angry Birds TV series, board game, soft toys and PC games coming your way soon.

Smaller scale profits

Don't be put off by the Angry Birds figures, though - there are developers out there making a tidy profit from advertising on free apps that are nowhere near that scale.

One of them is Neil Inglis, the creator of Sleeps to Christmas, who took time out of his busy schedule to talk to us. We asked him how he got into developing apps:

"I've been a software engineer for six years, but always on large systems that took months to develop and even longer to deploy!" he said. "The idea of being able to produce a small, self contained app that satisfies the needs of a user and lets you see results instantly really appealed to me."

Inglis has developed a few apps, but what has been his best creation so far? "Sleeps to Christmas has been my most successful. It's a small, fun application that really appeals to children and families. I've had over 1.5 million downloads and [the app has] spent some time as the number one top free app in the UK. The app is ad-supported and brings income in the tens of thousands of pounds a year."

So, is developing apps now his only source of income? "I'm at the point where I could sustain myself purely on developing apps," he says, "but I'm somewhat nervous about the stability of the income so I'm not quitting my day job - yet."

What model does Inglis think works best - selling apps for free with advertising, or just publishing paid-for apps?

"It very much depends on the type of application," he explained. "For apps marketed at the 'mass market', advertising works really well, but you need to ship in large volumes. For specialist apps, you'll never make enough out of advertising, no matter how targeted, so paid is the way to go. There are still issues convincing users it's worth paying the price of a cup of coffee for an app, but I hope this changes in the future."
