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.
This app is great - I'm pretty bummed to just have found out about it now, while they're in the process of turning off the service in June 2018. Hope there's another app i can find that works similarly... AirTable is great, but I can't use it for a full database for certain projects because of their freemium account limits.
This app is simply amazing! I have been using this as my replacement to Google Spreadsheets. The features inside of this amazing service are endless. If you have lots of data and want to organize it efficiently, this is the app for you :)
We started using Airtable to manage our content projects at work. After using it for a month, I decided I liked it so much that I signed up for Zapier and Airtable to manage my personal projects as well. It has completely changed everything.
