Our product roadmap

We make a priority to talk and gather feedback from users continuously.

Our goal is to build a tool you will love and a tool that will help you make better decisions. We are a small team, we work hard, we code fast and we turn around new features quickly. And it's a lot of fun for us to build a useful tool for our users.

These are some of the areas we will be focusing on. Please, get in touch with us and share your wishes, needs, ideas and suggestions.
