Version 1.1 of Standup Timer has just been released. This new version stores statistics for your stand-up meetings on a per-team basis. Simply create one or more teams using the new Teams menu option, then specify the team holding the meeting when starting the timer. To view statistics for a given team, use the Teams menu option to pull up the list of teams, and select the team you would like to see statistics for. The Stats tab will display the average statistics for that team across all of its meetings. For a list of the meetings that team has held, click on the Meetings tab. Finally, to see statistics for a specific meeting, simply select the meeting from the list of meetings.
Standup Timer is free and open source. The source code can be found at http://github.com/jwood/standup-timer. Standup Timer can be found in the Android Market.
