4 stars: It does very well for a complex software on a small screen. My biggest gripe, though, is that it doesn't use my default keyboard. I therefore have no autocorrect feature and have to make sure all text is spelled perfectly using the keyboard. Also, I would like the ability to jump to the end of a line of text when editing.
5 stars: As I'm a bit of a spreadsheet freak, I use this for my personal needs every day. Works perfectly! May be a little inconvenient to use if compared by desktop version, but that's expected for mobile devices.
3 stars: Need to be able to print and save pdf selection only. Printing the whole sheet is useless. Unable to do this from android device or even through chrome after forcing it and deleting the app. Surely you can handle such a small request!
4 stars: For Google sheets on the phone it's pretty good. I can't think of anything to make it better but won't give it 5 stars because I don't want people to think it's absolutely amazing. It works well, works how it should and is usable. If you're used to Microsoft it can take a bit to figure out the differences. Good app for phone. Couldn't be better but don't expect an incredible excel sheet, I don't think that's possible on a phone.
4 stars: Works great and regularly receives updates. However, I think something is wrong with the latest update concerning downloading a sheet and sending one. It seems to corrupt and wont open and also tells me that there's an incomplete upload but ...
