Already this week, we showed off a collection of , took a look at , and let you know about ; over at TechHive, we told you about the updates to .

Here are other new and updated apps that caught our eye this week:

: We admit to being fond of this for iPhone and iPad, and this week's update made Feedly even better: In addition to being optimized for iOS 6--a week ahead of time!--the app has been redesigned and loads faster than previous versions. The app now has both "day" and "night" themes, and it supports both Pocket and Instapaper. Feedly also contains a feature we'd love to see in Flipboard itself: A "save for later" button that lets you revisit stories within the app itself, instead of having to shift to another app for those rainy-day longform stories.

: When Facebook bought Instagram earlier this year, the idea was that the picture-sharing service would be more tightly integrated into the larger social network. That's happened, but the new app for iPhone suggests that that Instagram might be sustaining its own independent network. While Instagram lets users publicly comment on each other's photos, InstaMessage offers them the opportunity to chat privately. There must be an audience for that feature: As of Friday, InstaMessage was already at No. 2 on Apple's chart of most-downloaded free apps.
