I'm catching up with several of the iOS app updates which dropped during the first part of this month in one post:
Groundspeak's Geocaching App for iOS was updated on the seventh. Version 4.2.2 addressed several issues in the app but doesn't add anything new. Sadly I've not been able to find release notes on the Geocaching forums for more information than was provided in the update screen.
PiGo was updated to version 1.2.1 on the eleventh. This version simply contained a work-around for the web site login issue.
The new "CacheMe" app also saw an update on the eleventh. This is the first time I've written about this new app which connects with Garmin's OpenCaching.com site.
The iOS app simply titled "Caching" also has received an update to version 2 on the seventeenth. It now features file transfers within iTunes, Geocaching.com compatible field notes, information about travel bugs within a cache, iPhone 4 support, and more.
MotionX GPS version 15 also dropped. I've been ignoring many of the subtle updates this app has received, but this is a major release with several new features. The full version is still $2.99 for new users, and the lite version is still free to everyone.
