Is there an app that tracks cabin availabilities?

For example if a preferred suite is sold out on an upcoming desired cruise, is there an app that can track that for you?  

 

Thanks in advance.

Asked many times. 

Short of doing a mock booking for each class of cabin no.

One UK company has the capability to do a "Scanner" for cabins.  But even that site cannot sort cabins in a group block that are sold vs. unsold.  A US large TA has a slightly more cumbersome website.

Pretty much I look to see if my company still has group block cabins available and can see how they are booking.  Then at final.payment date you can see how many cancelled their bookings - often 10%+.  If prices then drop bookings are down. 

Last, today demand is very high.  Especially for cruises that vary from the usual week in the Caribbean or Alaska.
