Pretty detailed, right? Sure... as long as you have no interest in how Oakland scored those five runs in the first inning or how Jason Bay is faring in that game. To get that kind of data, you've got to launch the in-app browser, which takes you to a slightly more detailed view of what you've just seen. (It adds pitcher and batter stats, and tracks pitches of the current at bat.) But you were looking for a scoring summary--you've got to tap on a separate tab to get that and yet another tab to confirm that Jason Bay is O-for-1 with a strikeout.
To be fair, SportsTap and Sportacular don't cram all that information into a single screen. But they also don't force you to launch a separate in-app browser and then fumble around for tabs to find the information you're looking for. Tabs for scoring summaries and team stats are visible from the main game page in both apps. I suppose ScoreCenter's GameCast approach makes it easier to get live updates as they happen--the browser view periodically updates--but the price you pay is a cluttered interface that makes it difficult to find what you're looking for.
When I looked at scoreboard apps last year, I gave the edge to Sportacular, though many of my colleagues here at are full-throated fans of SportsTap. I have to admit, I'm gradually inching toward their way of thinking. I still find SportsTap's interface a little too spartan for my tastes, and I don't care for its behavior of automatically launching to the last page you had open, even if it's a game that was completed yesterday. (In fairness, you can go to Settings to turn off the Last Viewed Page feature, but that means you land on the home screen each time you launch--during baseball season, I'd like the app to open on the baseball page.) But I absolutely love SportsTap's use of the iPhone's Location feature--a LocalTap icon shows you the scores of any team located in a 50-, 100-, or 200-mile radius.
What's more, since my last review, SportsTap has added an alert system that helpfully lets you get notifications when games start, stop, and change scores. You can set alerts for specific teams or that day's games. (The feature is limited to in-season sports leagues--Major League Baseball and the Canadian Football League--but SportsTap promises to add NFL, NHL, and NBA alerts in the future.)
The implementation is not exactly perfect: I can't seem to find a way to alter the notification so that only a text alert pops up instead of the default alert featuring both text and a rather loud chime. Also, I tried turning off the alert feature once, but it didn't take the first time; I had to go back and disable it again. These hiccups aside, score alerts are a great addition to SportsTap--one other apps should adopt themselves. The feature really bumps up SportsTap in my estimation.
