Although it won’t appear for a few more days whilst the app goes through Apple’s review, the team behind Geocaching.com have written their own iPhone client. The cost of the application is $9.99 (UK price to be confirmed) and has the functionality you need to look up and seek out caches using the networking and location-based features of the iPhone 3G. It also works with the iPod Touch and first gen iPhone though you will need WiFi for the Touch and the compass won’t work.

The first release will not have the feature to log caches or filter hides and finds, but it will be included as a free upgrade as we add that functionality – hopefully over the next month. We wanted to get the application out as soon as possible since the demand was so high for it.

Some non-obvious features:

• You can look up travel bugs and find out their goal while out on the trail
• Saved Items allows you to save a cache listing and navigate to it, even when you are out of network range
• The application starts in beginner mode which only shows traditional caches. Advanced shows all types
• To help with speed issues on, say, the Edge network, you can restrict the number of results to 5, 10, 15 or 20
