Apple has approved FRC Tracker 2009 version 1.3. It should be available from the App Store within 24 hours. This version is a static representation of the results from the 2009 competition. It will ignore tweets from this year's competition. Before the 2010 game details were available, I wanted to work on new features so I just added them to the 2009 version.
New Features
---------------
OPR/DPR Ranking: If you go to an event, then tap on the Rankings button, you'll see the teams for that event in rank order. A new control at the top lets you choose between sorting by FIRST's qualifying round rank, Offensive Power Rating or Defensive Power Rating. If you're not familiar with OPR/DPR, they are explained in various places including
this post that explains what it is and how it is calculated. The little triangle gizmo will reverse the order. I'm going to make a change to how the reverse order button works, for now just keep in mind that large OPR values and small DPR values are good.
Robot Photos: FRC Tracker can download robot photos from TheBlueAlliance.net. For the ideal appearance in FRC Tracker, the robot photo should be 320 pixels wide and 367 pixels tall, or larger in approximately that same ratio. Really, anything that's approximately square will be fine. Photos that are really tall and narrow don't look nice, and photos that have been letterboxed with black bars don't work well. If your robot is tall and narrow, you can make your photo more square by adding team members or field elements on the sides.
Bug Fixes: A couple of minor bugs were fixed.
FRC Tracker 2010
-------------------
The 2010 version is making good progress, I hope to submit it to Apple soon.
In addition to the features in 2009, the 2010 version will have support for sorting by approximate rank when the official FIRST ranking data isn't available. This is especially handy when the FIRST rank data isn't available and there haven't been enough matches to calculate OPR/DPR.
As soon as I have a usable version, I'll submit to Apple. You never know how long it will take to get approval, and I want to be sure there's a version available for the Week 1 regionals.
After the initial version is done, I've got some other features I'd like to add, most notably the ability to add robot photos via the camera and photo library on the iPhone or iPod Touch.
