Mental health apps: stress, anxiety and mood

A mental health app can help you calm down in a hard moment, notice patterns and build small daily habits. It cannot replace a psychologist, a psychiatrist or emergency help. Mental Health SOS has quick calming tools, HMARA helps you talk a feeling through, and synappro breathe guides breathing.

How we picked: apps from the Censuus catalogue whose own store description is about stress, anxiety, mood or therapy support. Features come from each developer’s description. These apps are not medical treatment. If you are in crisis or thinking about harming yourself, call your local emergency number or a crisis line now.

Calm in a hard moment

Mental Health SOS has quick tools with breathing and grounding for anxious moments, plus guided meditations. Pixel Thoughts is a short interactive exercise: type a worry into a star and watch it shrink. synappro breathe guides breathing with an animation you follow. More in anxiety relief apps and breathing exercise apps.

Everyday stress and mood

StressLess combines meditations, breathing and mood check-ins. HMARA lets you talk through a conflict or a fear and, over time, shows recurring themes. Keeping a simple daily record helps too; see how to keep a mood diary and meditation apps.

Alongside therapy

Marram is a diary card for dialectical behaviour therapy, and Steadyline records both low and elevated moods for a psychiatrist; see bipolar mood tracker apps. Both are made to support work with a specialist, not to replace it.
