My favorite app gets better and better FBReader keeps surprising me with new features (PDF and multi-window support!)  listening to user input  and frequently updating with fixes big and small. Minimal permissions needed (like most apps *ought* to have). No intrusive ads. No constant pop-ups asking for 5-star ratings on the Play Store. And--most importantly--it just does what you want it to do  bells and whistles optional. If only all my apps were written by FBReader's authors!
