The usual caveat applies: it’s just a list, and thus by definition subjective: The 100 Best Android Apps. The selection looks good, though. It lists several of the tools that I installed after a personal inspection of the alternatives: Go SMS Pro, My Tracks, Camera360, Barcode Scanner, Evernote, Google Docs, KeePassDroid, Andricious and Read It Later.
For e-book reading I prefer Aldiko, however – mainly because I use my smartphone to catch up on technical articles, magazines and books that are usually published for free in HTML or PDF format, or that can be easily transformed into epub (Calibre, anyone?). My todo’s are stored in DGT GTD & ToDo which turned out to work quite well, especially for an alpha product. My streaming radio (essential for a commuter with bad FM reception) is handled by TuneIn Radio.
