My normal bathroom breaks are very long when I'm home and I have my laptop with me, but I can't do that at work (small startup, one bathroom) so my breaks are short and I just sit there collecting my thoughts. Bonus: Alkido. I've installed Alkido and read a bunch of books (epub) on my phone. I read during commute. I haven't found other apps that don't suck (they all ask for way too many permissions, access contacts and information like WiFi, etc, which I find ridiculous).
