I needed a decent reader which I could simply upload my pdf and epub books, with my own directory structure to it and not using tupid internal collection concept. JUST PLAIN FOLDERS full of books from my computer.
After testing nearly every app I must admit "TotalReader Pro" is the one that does exactly what I need.
"tiReader" was also good but trust me "TotalReader Pro" is much faster with heavy 100MB+ books.
