this app puts everything Google in one place. but there are plenty of glitches. using Drive is really slow to open and when editing, the scroll feature is really laggy and the cursor is never in the right place. it floats "above" where you want to type and theres no easy way to navigate in the document when editing. seems like this wasnt actually made for touch devices.
also, when opening app, password protect doesnt always show up or even work. multiple times when password request had been set, the password screen would appear, but no keyboard! then if you just close the program and reopen, you can bypass the password lock automatically. so as for security, this is not up to any sort of standard.
all in all, it does the job, but really only barely. as far as mobile apps go, this is sadly probably the best around. perhaps one day app developers will truly make mobile computing a priority instead of an after thought.
UPDATE: down from 3/5 Stars to 1/5
now the app is slower than ever! stupid ads every time you open the app and the push notification NEVER works properly anymore. doesnt notify when theres mail and if it arbitrarily does, wont get rid of the badge after Ive read it. obviously the developers have abandoned this app. junk! better off using actual gmail app even though you have to have a separate app for Drive & Google+. this app is not worth the stress.
