Postcode Envy for iPhone has just gone live in the iPhone App Store. I really enjoyed doing this app as everything from design to development was under my own control. With the app, you can:

• See house prices for postcodes in England and Wales.
• View area ratings for these postcodes.
• Compare average house prices across postcodes.

There are a number of ways to get the skinny on a postcode. You can look up postcode data for:

• Your current location.
• A postcode you choose.
• A random postcode.

FYI the app only provides house price data for England and Wales.

As with the iCondom, I did the backend of this app in Ruby on Rails with JSON for transport. I’m finding the combination of Rails + ActiveScaffold + ObjectiveResource to be the fastest way to get apps of this sort up and running, much faster than any of the frameworks and tools I’ve tried for PHP and Java.
