Alec Kinnear reviewedFieldbookCreate a database, as easily as a spreadsheet
 RecommendedPros: 

Works basically like a spreadsheet

Cons: 

Basic functions like sum don't work as expected

Fieldbook is obscure enough that it offers more privacy than Google Sheets (data directly linked to your Google profile, directly searchable by CIA/NSA, etc). Unfortunately Fieldbook is also Silicon Valley, ex-Googlers and ex-Grouponers so I wouldn't keep anything too private there. US privacy issues limit its usefulness.
