Twitxr is a native Twitxr client.

The service Twitxr is quite like Twitter but this service focuses more to Picture sharing than just sending quick updates of what you’re doing like Twitter.
The official statement on there website is:
» Twitxr 0.5-3

Collage is one of the iApp-a-day apps. It is one of the few applications that still receives updates.

Personally i don’t like this tool that much, but if you like sharing a picture or if you like being a voyeur :), then this app is for you.

Collage gives us the possibility to look at other people’s pictures and to upload one of our own to the system.
