Keeping all of that information organized will be a challenge. Probably the best-known information logging software is Evernote. The software lets you capture darn near all video, audio, images and text with applications that run on your Mac or PC, phone, or Web. Evernote synchronizes all of those, so no matter how you capture the information it’s stored in a common log.

LiveJournal lets you maintain a personal diary online. There are privacy restrictions on everything you post, so you can determine who views the particular piece of content. Share or keep private your thoughts as you see fit.

Still, you can’t display GPS and location-based information easily in this way. The open-source world has done some work in this space, but for the most part it's meant for scientists and developers. Gpsbabel converts waypoints, tracks and routes between popular GPS receivers and mapping programs. SpatiaLite adds spatial data to SQLite, the popular open-source database.

In truth, I haven’t found anyone who provides a comprehensive LifeLogging tool. By comprehensive I mean one that has the following three features:

• A single repository for all of my information—audio, video, images and body characteristics. Such a repository would need the data to be time, date and location stamped.
• An application that presents information in a single comprehensive, searchable timeline.
• An application that gathers all of my information passively.

If LifeLogging is to be effective, it must be made simple. Few of us would be willing to spend the time to record our body mass each day. If we want that at all, we’d like it done automatically. The Flip video camera innovation, for example, wasn’t in taking pictures. I could do pretty much the same from my existing phone. The Flip’s innovation was in making picture and video publishing simple, and it was rewarded by getting acquired by Cisco. The reward will be similar for the company that develops a comprehensive LifeLogging tool.
