Whilst the only bit I tried, MyDocs, worked it didn't take any account of the device screen size and was too small to read. Similarly I had to turn my phone on it's side to get the icons on the first screen to a size I could read.
I was unable to do a lot with this area of the app. I was unable to select any period date end when I tried to enter my time sheet. I think the app has great potential especially if you are able to export the expenses to the portal. I expect to give it a better rating if the bugs get sorted
The only bit I was interested in doesn't actually work
