Heuristic mobile analysis

A qualitative and evaluative method.

360º Expert App Audit is a heuristic evaluation process that relies on Nielsen Norman and Rolf Molich usability principles enriched with custom categories from a broader user and business perspective.

Heuristic evaluation is a structured approach to testing the apps' usability by considering known heuristics.

We use it to eliminate significant usability and growth issues without involving real users.


You will need at least 3-5 experts to do the 360º Expert App Audit. It does require at least one experienced evaluator. From the Infinum team, you are looking for Product Strategists, growth, QA, and other UX specialists. From the client's team, you are looking for a marketing specialist, product manager, content specialist, etc.

To prepare for the analysis, we suggest you get acquainted with 10 Usability Heuristics for User Interface Design by Jackob Nielsen.

360º Expert App Audit and Website heuristic analysis are the only two user research methods we conduct — without users. This is because they rely on frameworks that consider well-tested and proven usability principles (heuristics). So the focus is still on the user's reality.


You can do the 360º Expert App Audits in any phase of the app's lifecycle. For example: use it in the wireframing phase as a checklist to make sure all the usability principles are being taken into account or in the optimization phase of an existing app with active users.

Examples of use cases for the 360º Expert App Audit:


Part 1 — preparation (4-8h/person)

Do the research regarding the app you will evaluate - what is the app's goal, the main functionalities and features, and target audience/personas.

Once you know everything about the app goals, organize the heuristic analysis workshop. Schedule two hours to do the workshop and invite all the stakeholders that will participate in the audit.

Decide who will be facilitating the workshop, and prepare the sheet framework and the FigJam board. We suggest that every evaluator does the work in a separate sheet, as we all like to adjust to others' opinions.

Part 2 — the session (3-4h/person)

So, this is what the sessions look like:

After the analysis using the questions stated in sheet, you will have a quantitative overview of how well your app performs in these 10 categories:

The most probable outcome is that you will wrap the analysis up by realizing the app has some potential for improvement. And you will ask yourself — what do I do with these results now?

Part 3 — make it actionable for homework(2-3h/person)

End the session by giving the homework to the evaluators.

Guide them back to the FigJam template you have prepared. Split the categories among yourselves. Show the basics of FigJam to the evaluators and tell them their homework will be to:

Part 4 — prioritize & wrap up (2-3h/person)

Meet again and:


You can do the 360º Expert App Audits whenever you want to test the UX, content, design, or growth opportunities of an app. You might notice that you might test the same thing by doing usability testing. So, what's the difference between usability testing and heuristic analysis, and why would we ever use heuristic analysis?

Well... Usability testing will only get you the answers about people's reactions and behavior they are aware of. They don't always tell you much about deeper, subconscious principles.

Moreover, the fact that the people know they are being tested changes their behavior and answers. The discrepancy between people's socially desirable responses and their real behavior might lead you to make faulty assumptions and build a product that isn't what you looked for.

The advantage of heuristic analysis in this context is that it considers subconscious principles. It relies on a structured, tested, and proven heuristics framework.
