How Much Should it Cost to Develop a BlackBerry App?


blackberry dev costs

ScreamingToaster has made a few BlackBerry apps that are available in App World they have an interesting blog post on the cost of mobile app development. The post attempts to dispel some myths about the development process as well as shine some light on the costs of developing a smartphone app. One of the more interesting parts of the analysis is a breakdown of the three types of people you will meet as a mobile development shop for hire:

1. People who think that mobile development should cost no more than $5-10K, regardless of what their requirements are (because their requirements are always ‘simple’, so they claim).
2. People who think that web views that pass for mobile apps should cost between $10-20K. These people are being taken for rides by a lot of ‘consulting’ companies.
3. People who think that mobile development should cost over $250K for any mobile project. Some lucky consulting companies (who have very few customers) are getting very lucky from this group of people.

Figuring out what to pay to have your mobile app developed depends on a lot of factors and determining what to charge is equally difficult. Read the post for the full analysis of app development costs and factors.

How to write your first BlackBerry application – Lesson 1: UI fields


software development

This article is the first in a series of articles about BlackBerry development. With App World, third party software vendors and the web, there are a ton of opportunities for an independent developer to make money.

BlackBerry Development in Java – Lection 1: Basic fields in the User Interface

Let’s get right into it. Download the JDE (Java Development Environment) from the BlackBerry website. I personally used the JDE 4.3 for this project but you can also download a newer JDE. For advanced functions like using the BlackBerry Storm accelerometer or touch screen, you have to install JDE 4.7.

For advanced features and other APIs you may want to use, you need code-signing keys from RIM. You can purchase signing keys here. The keys cost $20 which is a bargain considering you can use the keys forever, and they’re going to help you make a great BlackBerry application. Make sure to read more about the keys because they’re an important part of BlackBerry development.

For this introductory application, you don’t need signature keys and the compiled *.cod file can be run on the device (and not only on the simulator).

How to develop and market a 3rd party BlackBerry app

As a BlackBerry developer, I have my own ideas about what makes a great BlackBerry application. I took the time to develop a list of concepts that I believe are important in the development process.

1. The User Interface (UI)

It’s vital to choose an appealing and not too over-done and crowded user interface. For the user it is essential to know from only looking at the interface what he has to do and how he sets the options in the application. Give your fields, check boxes and radio buttons appropriate titles or subjects. Short, descriptive words are a must.

I have already seen some utility apps where the UI is awfully crowded in the main screen. You look at all the options and feel like de-installing it because you will never know what all those buttons and checkbox do. Match similar options and put them into a separate screen with an appropriate title. Think about the novice BlackBerry-user, they don’t know all those settings and what they will do when you select them.

Even though I talked about an appealing and nicely looking UI, you cannot compare the iPhone user interface of applications to the rather sober-looking interface of BlackBerry apps. The BlackBerry OS is not aimed at fancy looking UI-Applications; it keeps the business factor. Personally, I love it!
