Testing the Adherlo app in real life: what we learned from users
In October 2025, Adherlo commissioned terzStiftung to conduct a real-life usability test of the app. Direct observation helped the team see the experience through users’ eyes: what they understood immediately, where they hesitated, and which improvements deserved priority.

Observe real use, not assumptions
Participants worked through the Adherlo experience in a realistic context. The session examined how they understood the app, navigated its main interactions, and related the digital experience to familiar medication-planning tools.

The most useful signals were not limited to what participants said. Questions, hesitation, successful first attempts, and the need for explanation showed where the experience already matched users’ expectations and where it needed to become clearer.
- First-use behaviour reveals where extra explanation is required.
- Hesitation can expose unclear wording, guidance, or interaction order.
- Successful first attempts show which patterns already feel familiar.
- Observed behaviour and participant feedback together support better prioritisation.
Turn observations into product decisions
The findings helped Adherlo prioritise refinements to software interactions and to the connection between the app and physical medication-planning tools. This was a usability test, not a clinical study: it supports product decisions, not claims about medication adherence or health outcomes.
The clearest lesson was simple: watch how people use the product, then improve the moments where their expectations and the experience diverge.
