Here are my conclusions after looking at the data during the trading hours:
The data for Dow Jones Industrials Average Index is not available in Blue stock market app. Futures symbols are used instead and they are one hour delayed, unless you have real time data subscription for CBOT or e-CBOT:
DJIA.CBOT - this is F-DJIA in watch lists pre-installed with Blue.
DJI.CBE - updated only during the night session, no intraday charts.
YM.CBE - 24 hr Globex symbol (mini $5 Dow futures). Less delay than with DJIA.CBOT (full futures contract).
In that case, Bloomberg Mobile seems much better for monitoring US index quotes, as the delay is only 15-20 minutes.
On the other hand, Blue looks ok for watching Canadian stocks and indexes. They have standard 20 min delay.
BTW, if we are talking about stock market apps. There is also a very good website designed by Barchart data service that offers interactive quotes and charts. Here are a few examples:
