I have one of these, there is an open source project called gshock_api that supports it. I think that makes it a much more interesting device. I don't use the app, I tag alarms in remind, and sync them from cron - works great.

The full lifelog (what Casio calls the steps and other metrics) is an opaque binary blob, but we mostly understand it now, so you can access that too.
