Google Drive/Dropbox: As cloud computing takes over harddrives or portable storage. With usb sticks and harddrives is that there is always one horror story of how viruses ,physical damage or both have lead to ost data. Drive and Dropbox eliminate that make those nightmares a thing of the pass 5-15 GB of free storge plus the much storage supplied after a small fee. I would recommend Google drive as a better application as it has a better sync with your gmail and chrome.
Wunderlist : This is a brillaint To-do list for organization probably the best out there on the app store. Can be sync with your phone and tablet. Notes and collab with college mates on possible project this is excellent , although sync with a IOs,Android,PC,MAC and chrome.
Google Keep/ Calender : Once again Google productive power comes out with a new organising tool , but keep appears like sticky notes to been messy and not as co-ordinated . Keep is relatively new so more feature are yet to come , such an app for a tablet . The sync with gmail as ever is handy for keeping thing to one account meaning less login details to remeber. Google Calender another tool for scheduling.
Evernote. : This was designed specfically in mind for college/students in mind . It great for question papers with out using paper ( great for the enviroment) . A stylus for ipads or samsung takes some getting used to but eventually starts to feel like a pen.
Anydo . This To-do although not as detail as wunderlist . Its beter run on lower androids OS
and straight foreward it also syncs with chrome ,phone and tablet.
My Google basis is strongly sense but from experience this works syncing make things a lot easier and saves on space . Also Google updates keep the apps running smoothly.
