@PurpleCar I have not. I find Overdrive easy enough to manage my holds/downloads that I haven't looked at others. I like how the audio doesn't crash my running apps, something I've had trouble with before with podcasts, Pandora and Spotify.
@susan I had a look at Libby when it first launched and it looked identical to the odious Overdrive. Should I check it again? The classification system is also a joke. I’ve been told Overdrive control this, not the libraries.
@MsPraxis I think the UI is better, and the audiobook player is great - that's really what did it for me, as I listen to a ton of them. However it's still using the Overdrive system, and I think their filtering algorithm is terrible.
