What is the mobile app market in term of downloads and revenue?

App market soars with 13.4 billion downloads in Q1 2013 (Apple’s App Store, Google Play, the Windows Phone Store and BlackBerry World).

11% increase in app downloads over all of 2012 combined. This means a total revenue of $2.2 billion ($0.16 per download).

Apple’s App Store accounted for the largest indexed proportion of revenue between the four stores, at around 74%, while the Google Play store saw the greatest number of downloads, accounting for about 51% of the stores’ collective total, with Apple close behind.

According to the numbers it should be easier to make revenue on iTunes than Google Play. It also depends on your target and their phone usage.
Example with my game, Geogames World Series – iTunes Store:
85,137 downloads
$15,033 sales
$0.18 per download

Top 25 developers make half of all U.S. mobile app revenue including Rovio, Zynga, Electronic Arts, and Disney.

What is the perfect recipe to create and sell successfully an application on the iTunes store?

Having a good idea is great as having an idea that will be easy to develop.

Before starting your app development, make a Google keywords analysis based on your idea to find a popular name for your app and assess thru the competition what is the minimum feature set to provide for version one

Use a marketing budget to write your app description, communicate to press specialists, and initiate reviews by users as soon as the app is published.

Trade marking your app name is highly recommended.

Choose a business model for your app between free app with ads, in-app purchase, and paid app. In app purchase requires more programming.

Propose something different from the crowd (it can be something already existing in the market but you add a value in term of usability / design / functionality).

Find the best people in the community to work with (developers, app marketers, graphic designers, translators).

Understand very well the specificity of your store like iTunes or Google Play (1 to 2 weeks to publish on iTunes, less than 1 day on Google Play – Discount for education in iTunes store).

Localize as much as possible (GeogameÔ World Series translated in 9 languages).

Use iterative project management techniques to manage your software development (Scrum, Extreme Programing XP…).

Use minimal design to fit within your iteration time frame (2 to 4 weeks recommended).

Each iteration should deliver a shippable peace of working software that you can publish as a new version.

Use an online project management tool like Pivotal Tracker to communicate every day with your developers and remove impediments on the go.

What is the minimum investment?

The following example is based on Geogame™ World Series

Video launch 1500 (optional)

App Marketing 2000

Programing by a good developer 10 days x 500 = 5000 by iteration

Graphic design 1500

Translation from 200 per language (optional)

Total minimum cost: 8.5k

How can we assess a very high quality of software source code?

OOP: Everywhere appropriate, favor instance object over instance variable.

DRY: Don’t Repeat Yourself!

Comments: Every function should have a brief explanation. Special routines, important helpers, and workarounds should be explained.

Shorthand: Code will be written in shorthand employing shorthand notation where possible.

Use naming convention shared by the community for clarity of code.

Use design patterns (MVC…) to insure decoupling, reusing and other software virtues.

Use third party source code promoted by the developers’ community.
