It's UI is simple, clean and straight forward. Never have had any issues with the product.

Clean, simple but powerful UI. Supports most major db types, can have multiple db connections. Switching between data and structure of a table or view very convenient. Custom sql statements can be saved for future use, TablePlus supports multiple statements in the same editor screen. Run statements in different modes: current or execute all. Provides detailed view on table, selected row, and you can see all at the same time: db structure, table, data, selected row content. Provides multiple tabs so you can query, run statements, view contents and/or structure of a table, etc, on separate tabs simultaneously. Overall performance very quick , consumes little memory.

The design is best in class; database managers are usually very techie. This appeals to non-tech users as well.
