### 5/5 — Stress monitoring

*2026-06-01, version 2.0.1*

Started using a few years ago. This really enabled me to recognise when I’m tired, stressed and just need a moment to compose myself. In the beginning I scored really low, and was able to recognise what improved my score and incorporate that more into my life. I’m now able to keep my levels fairly good and the notifications enable me to know it is time to rest. I enjoy having this app.
