What is the Clear Fear app?

The Clear Fear app by stem4 provides ways for children and young people to manage symptoms of anxiety. Developed by Dr Nihara Krause, a Consultant Clinical Psychologist, together with ideas from young people, the Clear Fear app uses a Cognitive Behavioural Therapy (CBT) framework to help change anxious thoughts and emotions, alter anxious behaviours and calm fear responses.


The Clear Fear app also has helpful descriptions of the different ways in which anxiety shows, resources and a ‘grit box’ to boost resilience.


The Clear Fear app is a self-guided tool that uses an evidence-based treatment approach called Cognitive Behavioural Therapy (CBT). It is not a substitute for the assessment and treatment of a mental health professional.

Who is the Clear Fear app for?

The Clear Fear app is recommended for the ages of 11-19 years. Younger users can work on several of the tasks with the assistance and support of a parent/carer or teacher.

How does the Clear Fear app work?



‘The fear of threat or anxiety is like a strong gust of wind, it drags you in and makes you want to fight it or to run away. Instead, face your fear, reduce the threat and glide.’


The Clear Fear app uses a Cognitive Behavioural model developed by a clinician in collaboration with Children and Young People (CYP). Cognitive Behavioural Therapy (CBT) is an evidence-based treatment to help anxiety disorders and is the first line treatment recommended by the National Institute for Health and Care Excellence (NICE).


The Clear Fear app helps users to manage anxiety symptoms by learning to regulate physiological responses through graded relaxation and breathing; to challenge anxious styles of thinking; and overcome behaviours associated with anxiety disorders such as avoidance in social anxiety and phobias and over-checking in obsessive-compulsive disorder.


There are also opportunities for emotional expression through journaling and self-monitoring through progress graphs. An Immediate Help section is available to help manage extreme anxiety or feelings of panic. Each user is encouraged to set up a ‘safety net’ when they download the Clear Fear app, which provides an opportunity to note anxiety-reducing thoughts and coping behaviours as well as list helpful contacts.


For those with severe symptoms of anxiety, the Clear Fear app can be used in conjunction with a mental health professional. Whilst Cognitive Behavioural Therapy (CBT) underpins the Clear Fear app, the app has been developed co-collaboratively with young people and clinicians. The Clear Fear app is password-protected and confidential.


Further detail


The Clear Fear app offers a selection of tasks, based on Cognitive Behavioural Therapy (CBT) and other evidence-based approaches that have been shown to reduce symptoms of anxiety (references available below). Tasks are accomplished in the following ways:


Goal Setting and Behavioural Experiments

Exposure based challenges form the foundations of Cognitive Behavioural Therapy (CBT). The Clear Fear app includes behaviour change techniques such as identifying specific goals, tailoring each goal to suit each individual, barrier identification, breaking long term goals into short term challenges, accomplishing easier challenges first, prompts/cueing, reinforcing success, social support and tracking personal information to enhance self-directed learning.


Cognitive Restructuring

These include identifying three common types of automatic negative thoughts together with self-monitoring, seeking evidence and restructuring thoughts. Therapeutic gains may include symptom relief and an increased sense of control over anxiety.


Strategies to Reduce Physiological Responses

Mindfulness-based exercises are available in both visual and auditory format to improve low self-esteem, emotional reactivity and improved functioning (Goldin and Gross 2010).


Emotional Expression and Regulation

The Clear Fear app provides children and young people with the opportunity to express their emotions through note keeping, find alternative ways of emotional regulation through a range of tasks, or to substitute negative emotions for positive ones through the use of humour or by selecting provided gifs.



Psycho-education is provided in the information section as well as in optional notifications sent to users in order to support their momentum in reaching personal goals, guiding them through the Clear Fear app as well as providing valuable psychological insights.


Among the suggestions provided are opportunities to learn to set realistic goals, overcome fears and increase motivation.


Information about Anxiety

The Clear Fear app provides information on the different ways in which anxiety may present, provides in-app task suggestions to help as well as books and resources.


Grit Box

Based on the concept that ‘grit’ is a necessary factor in resilience, the Clear Fear app contains a range of motivational statements, positive quotes, information on resilient and inspirational people generated by young people.


Dealing With Worries

The Worry Box provides containment of anxiety for the user, whilst the Worry Ladder helps the user prioritise anxieties together with problem-solving.



The monitoring section includes an anxiety profile and anxiety tracker to help the user self-monitor across every task. Therapeutic gains may include increased self-reflection and understanding, feelings of hope and increased control and confidence in the ability to regulate anxiety symptoms and a reduction in secondary anxiety.  Reviewing levels of anxiety helps make anxiety feel less threatening and therefore more manageable.  Learning what is a helpful strategy will also become clearer.

Is the Clear Fear app suitable to use for pandemic related anxiety?

Anxiety and anxiety disorders have increased considerably as a result of the pandemic. In order to support children and young people affected, stem4 has created an animated video and user booklet on how to use the Clear Fear app. This includes specific anxieties that may have increased during the pandemic, for example,  health-related anxiety or obsessive-compulsive symptoms and also outlining pandemic safe tasks which abide by safety guidelines such as social distancing.


The Clear Fear app use has increased by 40% subsequent to the pandemic and stem4 will endeavour to use the feedback we receive from our users and our focus groups to update the app.

What were the aims of developing the Clear Fear app?

To develop an evidence-based, widely accessible digital tool to help children and young people (age 11-19) manage their anxiety symptoms (younger with parent involvement). This includes reducing the intensity of anxiety symptoms, reducing the frequency of anxiety symptoms and helping identify underlying trigger factors together with learning alternative positive coping strategies.


To devise an anonymised analytical model to evidence effectiveness and inform future development.


To comply with NHS information governance requirements.


To raise the profile of stem4 and its work to support teenage mental health.

What evidence is there that the Clear Fear app works?

Pilot study:


14 young people attending a psychology service with moderate symptoms of anxiety were given the Clear Fear app to use alongside standard Cognitive Behavioural Therapy (CBT) treatment. They were assessed at baseline and given two screening questionnaires and their attitude to the Clear Fear app use assessed. The screening questionnaires were the Beck Anxiety Inventory for Youth (BAI-Y; Beck et al 2001) and the Strengths and Difficulties Questionnaire. The Clear Fear app was used in between treatment sessions for four weeks.


Acceptability (wanting to use the Clear Fear app) was 100%, Reported help with reducing anxiety symptoms after each use 96%. Overall statistically significant reduction in anxiety levels. The most popular category was ‘dealing with your emotions’ and ‘safety net’ followed by immediate help, information on anxiety types.


Whilst this is a non-control pilot study with a very small sample size, the benefits of having an ‘at hand’ prompt and support were highly valued by the young people who felt that they could both consolidate what they were learning in terms of anxiety management as well as have a ‘personal companion’ in terms of the Clear Fear app to help manage their symptoms. In addition, they were very positive about the fact that the Clear Fear app came from a scientific source and their parents were equally supportive of the fact that this could be a prompt they could use to benefit their children.



Clinical study:


A clinical study to evidence the Clear Fear app effectiveness is currently being carried out. Having received ethical committee (IRAS) approval in 2020 the study is being carried out by Informed Thinking, an impartial clinical research organisation for stem4. The research is part-funded by stem4 and a Nominet #RESET grant.


This quantitative and qualitative study uses questionnaire, interview and observational approaches to evidence symptom change in 50, 16-21 year-olds, monitoring symptoms over a 9 week period to compare pre and post measures of anxiety together with a range of other measures including their evaluation of the Clear Fear app features and usability. A peer-review paper will be prepared and submitted subsequent to the completion of the study.



Analytics from the Clear Fear app:


Latest Clear Fear app analytics data (up until the end of Dec 2023) tells us:

There have been over 820,000 downloads of the Clear Fear app to date.

92% of the individuals who used the Clear Fear app reported that an activity helped to reduce their anxiety.
