I ran into Graham Dawson at Barcamp, on the weekend, and was really pleased to hear about his his Oz Weather iPhone app getting to number 7 on the Aussie iPhone app list. Even more exciting to hear, however, was that he planned to release information on just what that meant in terms of distribution and dollars.

For those who don’t recall, we did an article on Graham and his experience building the Oz Weather iPhone App, a little while back. It was (and still is) a great resource for people considering moving into iPhone app development.

Now, Graham has gone and completely opened up the books and put it all in a post over at the Ajnaware blog.

He covers the costs, the sales volume, the revenues and the projections.

Interesting bits include:

• The cost of development was equivalent to approx. $15500
• The ad supported web app brought in approx $50 in revenue whereas the native iphone app at $2.49 has brought in approx $2500 in revenue (post GST and Apple’s 30%)
• To get to number 7 he’s sold 1586 units in 14 days.
• Break even point, if the current rate of approx 140 units per day is maintained, would be 2-3 months.

I won’t put anything else because I highly recommend you pop over and check out the original blog post, yourself.

Kudos to Graham for being so open. Hopefully others will follow his lead and help the developer community decide whether or not developing for the iphone is a useful way to spend their time.
