When it works, it's a great resource for looking up and reserving books throughout the King County Library System. It also syncs audiobooks and ebooks well with Kindle, Libby, or Overdrive. Unfortunately, it routinely signs me out automatically once a week and won't allow me to sign in for an indeterminate amount of time, which is quite frustrating.

New update terrible. App does not save passwords. Not intuitive to find shelves or navigate. Downloads to Kindle TERRIBLE. Once you finally figure out how to even check out the book, you are just put back to the original place to find by random searching what to do next. Then you have to figure out what to click (twice!) to actually download. Then you have to remember your Amazon password. I've given up several times lately and am reading a paper book for a while.

This is a wonderful tool (mobile management of account/holds/book lists/etc), but comes with some quirks. The biggest issue I seem to have is with the search function. When typing, the app seems to have a lag in which one or multiple keystrokes are skipped. It's not like this is due an autocorrect sort of function operating--I am not getting any predictive text suggestions. It just doesn't keep up. I usually have to erase my entire input and start over with very slow and deliberate typing. :-(
