Two more promising apps:
I’m a big fan of noise and music apps and podcasts for focus and sleep. Dark Noise 3 is a great one that was new to me. Especially its Green Noise sound is very soothing to me.
Sequel 2 is probably the first media tracking app, that I am actually using (for a few weeks at least). It’s easy to use and has just the right amount of bells and whistles. This works better for me than, say, Trakt.tv, because I don’t need nor want the social network aspect and I do want to track more than just one type of media.
