Transform your website or app from good to great. Our audit will help you understand where to focus to improve conversion and usability.


Our team will help you redesign your app or website to give it a new look and optimize it for your business goals.


Think of it as an expert review that gives you actionable suggestions on how to improve your website, app or platform. During an audit we look at every aspect of user experience. So not only design, but also flow, text and technical performance.

You’ll receive a report, highlighting the issues we’ve found. We prioritize these issues so that the final result is as actionable as possible for you.

The audit is based on UX best practices and heuristic principles. If you go for the tactical package, we also interview users for usability testing.

Usually we uncover around 4 to 12 issues per page we review. We weight them by priority (high, medium, low) to help your team decide where to start. We don’t want the issues to be too many because we want to focus only on what has an impact.

We look at different aspect of your product, not only design, but also copy and technical performance. So you won’t necessarily need a designer. However, should you need design capacity, we’re happy to offer it as well.

It can be any digital product: website, app or platform. We have reviewed fintech SaaS platforms, charity websites and even wearables. The review can be done on a live product or even on Figma.

We can audit products in any language. For audits with European languages, we pride ourselves of using local users to review the usability.
