Usually forget to send feedbacks so writing now when I just started to use it. So it’s just first impression from 1 hour using. Pluses: no ad. No forced registration. You may do it, but it’s not obligatory. It’s opening all standard formats of files like .doc, .xlsx, .pdf. Tried to make changes in MS Word document - no problem. Minus - no function to be able to open documents on the device in this app automatically. But you can download in this app documents from your devise or from cloud and then work with that copy. Didn’t find any bug for now. First app from the last 12 similar I tried which I didn’t uninstalled and going to use. So good start I think ) Thank you guys for good app and wish you will be developing.
