The smartphone has become a regular part of my daily workflow, and I find myself using it regularly for To Do lists, email, reminders, and keeping up to date on news and such. Recently, I've found a couple of apps that have been particularly helpful in keeping me on track, so I thought I'd share them with you all. There are some similarities in these apps: they all do one thing and one thing only, and they place a premium on doing those things as quickly as possible, so you can spend less time on your phone, and more time doing other things. Also, most of them have reminder systems built in, so you don't forget to use them to do the things you want to do. As a side note: I'm an iPhone user, and I've done my best to find alternative apps for other smartphones. Please use the comment field to add any useful alternatives for other platforms!
