In this day and age, this is one of the few apps with NO security to get into it. At least for the love of all things secure put a passcode to even get into the app. I and many others requested this years ago and they havent done that one simple thing. Cant use it and neither should anyone else, your data simply is not safe. If you connect and cloud services like dropbox, box etc. your data is not secure. Also has issues opening excel files with formulas it doesnt understand, this company is behind the times.
