You can start using the web version of their app right away by going to http://splitterbug.com on your mobile (at least it worked on my iPhone) and signing in with Facebook.
Good eye :) The web version lacks a lot of optimizations we were able to add on the client though. If you're excited to start using the thing now, shoot me an email at support [at] splitterbug.com and let me know what device flavor you prefer (iPhone/Android). I'll get you set up.
