This program has been out for a little over 6 months, and has gotten a lot of attention. You may recognize it because it shares a common name with a program that installs on your machine when you install Revit or ACAD, but there are some differences.
Overall, the program is fantastic. I am personally a fan of Design Review desktop, I use it quite a bit to do digital redlines (I believe I posted on this in the past, so check the archives) and like the workflow between the application and Revit (and ACAD) and back and forth. It's great for tracking changes, redlines and giving responsibility to tasks.
Design Review Mobile works essentially in the same way, it provides an ability to view dwfx files on a mobile device, (both android and ios). You use the Autodesk 360 website to upload documents to the cloud, then sign-in to the service on your mobile device to see the same sets of documents, download them and view them. 2D and 3D views are supported, however live interaction with a 3D view is not. You must plan ahead to which views you want to be able to see in 3D and then export those views specifically.
After uploading a file, there is a waiting period as the server process the file and converts is to be able to be viewed, but afterwards it is available on both the website and any device that connects to the Autodesk Cloud. The waiting period can range from almost instantly to 5-10 minutes, I have found that it all depends on the file size, how many 3D views are present and the server load.
Design Review Mobile includes most of the same abilities for markups as it's desktop equivalent, which is great for work in the field, however a large downside to the current technology is that markups done on a mobile device are stuck on the cloud, there is currently no way to download the markups from the cloud to the desktop and save them. I know of some people who have rushed into this technology in the past, not understanding this serious limitation, and after doing considerable work, discover that they cannot get the files off. Needless to say, it left some very unhappy customers.
Where I have found this technology works most efficiently is when you need to reference drawings or pre-set 3D views in the field. Load them up ahead of time (unless you have connectivity on the site) then if you need to look at something in the field, you can pull them up for reference. It's a one-way information transfer, but it is still a valuable tool and it beats carrying around rolls of drawings. Especially since you can have multiple projects (25GB of cloud storage if you are a subscription customer, which is a lot of projects) stored on the cloud for instant referencing anywhere.
The program doesn't always need a live internet connection to work either, you do need one the first time you download the drawings, but it does save them in the onboard memory, so you can open them from the local documents next time you want to access it.
If you develop a workflow that means everytime you update drawings, you export them to a dwfx, you also upload that file to the cloud, then you can be sure that you will always have a recent set of drawings available if you should need to pull them up for reference on a site.
Two features I wish they would add, a direct export and upload tool directly from within revit. It would eliminate the step of having to find the file, login to the website, and upload the file. You can already sign into your Autodesk Account from within the software, so adding this shouldn't be that difficult.
The second feature which is really limiting this app's ability is the fact you can't get markups off the device. You could share the document on the Cloud, but its not the same.
Since I have been paying attention to this app (4 months) there have been 2-3 updates to it, which is to say that Autodesk is committed to working on it and improving it. 6 months ago when it first came out and I was reading of its features, it had half of what it offers today, so I think it's safe to assume that it will continue to be developed in the future.
