Project management isn’t for everyone, but if it is a class of software you like to use then you may well already be aware of Basecamp. If you’ve never heard of it, then hop over to https://basecamp.com for a mooch around and grab yourself a 60-day free trial of the service.
If you are already a Basecamp user, then downloading the app for Android or iOS is a must, and will stand you in very good stead for working on the move because it gives you a link into your complete suite of Basecamp projects. You can see what others on your team are doing, look at documents, get involved in the bits of the project that you are responsible for, comment on this and that, participate in discussions, and so on. You can, in fact, work productively on the move.
OS: Android, iOS
Price: Free (main suite is charged for)
