The ubiquitous presence of mobile apps in today’s technology-driven world is undeniable. Towards the end of 2022, there were over 3.55 million apps available on Google Play Store and 1.6 million on Apple’s App Store (source).

Mobile apps have become an integral part of our daily lives, catering to our every need – from communication and entertainment to health and productivity.

However, with such widespread use, concerns have arisen regarding the addictive nature of these apps and their potential impact on our mental health.

In this blog post, I delve into some psychological research on the addictiveness of mobile apps.


  • The Hook Model and Mobile App Addiction
  • The Role of Dopamine and the Brain’s Reward System
  • Social Media Apps and Fear of Missing Out (FOMO)
  • The Negative Impact of Mobile App Over-Use
  • Limitations of Current Research on Mobile App Addiction
  • Strategies to Help Moderate App Usage

The Hook Model and Mobile App Addiction

To understand the addictive nature of mobile apps, it’s helpful to consider the Hook Model, a framework proposed by Nir Eyal in the book Hooked: How to Build Habit Forming Products (2014). Eyal suggests that successful apps are designed to create habit-forming behaviours through a four-step process: trigger, action, variable reward, and investment. By repeatedly exposing users to this cycle, app developers can foster compulsive app usage.

The Hook Model is supported by psychological research on habit formation and addiction. In one study (creatively named “The Candy Crush Sweet Tooth) researchers Chanel Larche, Natalia Musielak & Mike Dixon, found that individuals who scored high on measures of smartphone addiction exhibited stronger habit formation with their devices.

In another study, researchers observed a strong correlation between habitual smartphone use and addiction symptoms. These findings suggest that the mechanics underlying app addiction are closely related to the habit-forming properties of the Hook Model.

The Role of Dopamine and the Brain’s Reward System

Dopamine, a neurotransmitter associated with the brain’s reward system, plays a crucial role in reinforcing addictive behaviours.

Mobile app usage can stimulate dopamine release, leading to the formation of habits. In a study published in the Journal of Psychiatric Research, participants who displayed smartphone addiction symptoms exhibited elevated dopamine levels in response to smartphone cues.

The addictive potential of mobile apps is further exacerbated by the incorporation of variable rewards, which are inconsistent and unpredictable. This aspect of app design can heighten dopamine release, as evidenced by research on gambling addiction. In essence, variable rewards in mobile apps can hijack the brain’s reward system, leading to compulsive app use.

Social Media Apps and Fear of Missing Out (FOMO)

Social media apps are notorious for their addictive nature. One factor contributing to this is FOMO, a psychological phenomenon that describes the anxiety experienced by individuals when they believe they are missing out on rewarding experiences (source). Social media apps are designed to constantly update users on their social network’s activities, exacerbating FOMO and encouraging compulsive app usage.

A study by Ursula Oberst and colleagues in the Journal of Adolescent Health found a significant relationship between FOMO and social media addiction. Furthermore, they observed that individuals with higher FOMO levels were more likely to experience negative consequences associated with excessive social media use. This research highlights the potential dangers of social media apps, which exploit FOMO to foster addiction and compromise users’ mental health.

The Negative Impact of Mobile App Over-Use

Addictive app usage can have severe consequences on our mental and physical well-being. Research has linked mobile app addiction to symptoms of depression, anxiety, and sleep disturbances. In a study by Jon Elhai and colleagues in the Journal of Affective Disorders, a strong association was found between problematic smartphone use and symptoms of depression and anxiety.

Another study in the Journal of Youth and Adolescence revealed that excessive smartphone use at bedtime was associated with poorer sleep quality.

Limitations of Current Research on Mobile App Addiction

While the existing research on mobile app addiction has provided valuable insights into the addictive nature of these technologies and their potential negative impact on users, there are limitations we need to be mindful of. Some of these include:

  1. Cross-sectional design: Many of the cited studies employ cross-sectional designs, which capture data at a single point in time. Such designs can limit our understanding of the causal relationships between app addiction and its associated negative consequences.
  2. Reliance on self-report measures: Most studies rely on self-report questionnaires to assess mobile app usage and addiction symptoms. Self-report measures are subject to biases, such as social desirability and recall bias, which can affect the accuracy of the data.
  3. Small and homogeneous samples: Many studies on app addiction involve relatively small and homogeneous samples, such as college students. Expanding research to include more diverse samples across different age groups, socio-economic backgrounds, and cultures could enhance the generalizability of the findings and provide a more comprehensive understanding of app addiction’s prevalence and impact.
  4. Inconsistent operationalization of app addiction: We don’t yet have a universally accepted definition and diagnostic criteria for mobile app addiction, and this can result in inconsistencies across studies.
  5. Rapidly evolving technology: The rapidly changing nature of mobile apps and technology poses challenges for researchers attempting to study their addictive potential. As new apps and features emerge, it is crucial for research to adapt and investigate the potential implications of these innovations on user behaviour and mental health.

Strategies to Help Moderate App Usage

Armed with an awareness of the psychological research on mobile app addiction, we can all take proactive steps to moderate our app usage and foster healthier habits.

You might find that by implementing the following strategies, you can start to regain control of your digital lives and minimize the adverse effects of compulsive app usage:

  1. Self-Monitoring: Regularly tracking app usage can provide valuable insights into personal habits and patterns. Most smartphones have built-in features that display screen time and app usage statistics. By reviewing this data, you can identify problem areas and set goals for more balanced app usage.
  2. Setting App Limits: Establishing daily or weekly limits for specific apps can help you regain control over your digital consumption. You can set time-based restrictions through your devices’ settings, or utilize third-party apps to create app-specific boundaries.
  3. Consider “Digital Detox” Periods: Designating specific times or days for a “digital detox” can help break the cycle of compulsive app usage. By disconnecting from your devices, you might be able to make time to reconnect with offline activities, such as spending quality time with loved ones, engaging in hobbies, or practising mindfulness.
  4. Disable Notifications: Constant notifications from apps can trigger the fear of missing out (FOMO) and contribute to compulsive app usage. You can disable non-essential notifications or customize your settings to receive only the most critical alerts, reducing the urge to check their devices constantly. Yeah, I know that puppy’s account on Instagram is adorable – but do you need to be alerted every time a new post appears?
  5. Establish Boundaries for Social Media Use: Given the addictive nature of social media apps, think about creating rules for their usage. This may include logging in only during specific times of the day, limiting the number of daily check-ins, or avoiding social media use before bedtime to promote better sleep quality.
  6. Prioritize Face-to-Face Communication: To counteract the negative effects of excessive app usage on social functioning, try to prioritize in-person interactions with friends and family. By dedicating time to face-to-face communication, you create the space to nurture deeper connections.
  7. Seek Professional Help: If app usage is causing significant distress or negatively impacting daily functioning, please consider seeking professional help from a mental health expert. Many therapists and counsellors can provide guidance and support for managing digital addiction and developing healthier habits.

By incorporating these strategies into their daily routines, you can start to cultivate a more balanced relationship with mobile apps and mitigate the potential negative effects of app addiction on your well-being. It is crucial to remain mindful of personal app usage habits and make conscious choices to foster a healthier digital lifestyle.


Mobile apps have become a ubiquitous part of our daily lives, catering to our every need. However, with such widespread use, concerns have arisen regarding their addictive nature and potential impact on our mental health. The psychological research presented in this post highlights the various mechanisms that contribute to app addiction, such as the Hook Model, dopamine release, and FOMO. Despite some limitations in the existing studies, the evidence suggests that excessive app usage can have negative consequences on our well-being. By fostering greater awareness of mobile app addiction and its consequences, we can ensure that these remarkable technological tools continue to enhance our lives rather than compromise them.
