I can do just about anything I or my users can think of. Knack fits perfect for our database needs.

I have used Knack to write two relatively complex database solutions. While I had to get used to some non-standard database terms (e.g. connection vs. join), I found it extremely easy to learn and use. The best thing about Knack is the support. Except for a brief span a couple of years ago, their responsiveness and helpfulness has been superb.

After a short but steep learning curve you become very productive, very quickly. For most common business applications Knack will have a template that can be used to start you off, and even if you start from scratch you're able to create a data model very quickly and then have Knack build your basic pages. It's easy to understand and simple to use. The UI customisation is not perfect yet, but if you have a basic understanding of CSS you can create beautiful user interfaces easily enough. The ability to build in business logic attached to fields, views or forms is very useful and intuitive.
