Good, but has plenty of issues.

This is definitely my go-to twitter app, but it hasn’t kept up with upgrades to the Twitter service, so I frequently end up viewing tweets in a browser anyway. A few examples:

The native image viewing only supports the first picture on a tweet and doesn’t give any indication that there are more.
If an image is animated, the native viewer only shows a single frame and doesn’t give any indication that it’s an animated picture.
Twitter’s new retweet functionality (where you can add a comment to the retweet) means you have to view the tweet in the browser to see the context, since Night Owl just shows the comment and a link to the original tweet.
