After a glance on the homepage, it seems that boostnote matches my needs on online notes, maybe I will have a try on it later, cuz I am not in the habit of taking notes :)

Last time I used notion, making a note about money I spend on a travel using its "database", I feel its statistics feature is little bit simple, which I can only do some basic calculation like sum or average on A SINGLE column.

What I want to do that time can be described using SQL like: SELECT sum(cost) FROM trip_cost WHERE tag = 'plane';

Since boostnote is a product facing programmers, implementing a subset of SQL may be not a bad idea if there were some feature about spreadsheets. But implementing SQL seems too heavy for a note app?
