Gowalla has released a major update to its location-based social networking application for the iPhone and iPod touch adding integration with competing location-based networks and a number of other significant new features and enhancements. Gowalla 3.0 expands its services to include Facebook Places and Foursquare, allowing users to connect to their other accounts to check-in and view friends’ check-ins across all three networks in one place. Check-ins can also be posted to Twitter and Tumblr for sharing. Users can now leave personal notes at a location for their Gowalla friends who will receive the note when they next check-in at that location and bookmark specific spots for later. Other improvements include faster check-ins based on user history, the ability to add and browse highlights for a city and the ability to flag spots to report problems or closed locations right from within the app. Gowalla 3.0 also sports a completely re-imagined user interface design to improve the user experience and makes uploading photos, creating spots and browsing friends much easier than in the previous version. Gowalla is available from the App Store as a free download. An iPad version is also available however it has not yet been updated to include these latest features.
