I absolutely love this! Personally I have made a few projects that use google sheets as a backend in order to give the non-dev owners control over their data.

I wonder if in this app you'll have some API access? I can see this a extremely useful to hand non-technical clients a very nice interface (better than a spread sheet) and avoid the user from breaking the app (i.e. "I didn't know that rearranging/changing the name of a column would break the app!")

I'm gonna keep an eye on this product. Thanks!
