Mood tracker apps help a person monitor their mood over time and learn how external factors, such as their diet or lifestyle, affect how they feel. Some are free, while others are upgradable or require a subscription.

Mood tracking could make it easier for a person to monitor their progress in therapy or the effects of taking medication. Furthermore, understanding how and when mood shifts happen could help a person identify important patterns in their behavior.

In this article, we discuss the best mood tracking apps and what to expect when using them.

Please note that the writer of this article has not tried these apps. All information is purely research-based.

Mood tracking offers many benefits. For instance, it may help a person:

  • identify triggers for bad moods, self-harm, and negative behaviors
  • create strategies for managing low moods and harmful impulses
  • monitor the extent to which medication or therapy is working

Research suggests that mood tracker apps are a helpful and safe way of offering support for young people to manage their thoughts of self-harming and develop a strategy to avoid this behavior.

Some mood tracking apps to try include:


MyTherapy makes it easy to identify exactly what actions help improve a person’s mood. A person can log their moods alongside the interventions they are using, such as medication, exercise, or eating and sleeping well.

From the inputs, a person can see how all their actions correlate with their mood. For example, someone could discover a link between exercising and feeling good afterward.

MyTherapy is free to download from the App Store or Google Play.


Breathe2Relax has an easy-to-use interface that allows people to enter mood information. Drawing upon this information, the app provides actionable steps for managing anxiety and depression. The user can then rate how well the intervention worked and get customized feedback for subsequent negative moods.

MoodKit supports mood tracking, but it also provides actionable feedback based on the principles of cognitive behavioral therapy (CBT). The app displays a person’s moods in week- or month-long charts, potentially making it easier for them to identify specific interventions that are effective in managing difficult moods.

MoodTracker has a free version, but people can pay for a version with additional features should they prefer. It is a web app, which means that it is not downloadable. Instead, a person logs into their account online.


Daylio expands beyond mood tracking, allowing people to jot down a few thoughts or keep a detailed private journal.

People who struggle with anxiety may feel overwhelmed with thoughts that they cannot control. Worry Watch tracks these thoughts and feelings over time, then categorizes them based on CBT principles.

A number of studies suggest that mood tracking apps could improve well-being over time. For example, a 2018 randomized controlled trial found that MoodKit and MoodMission reduced symptoms of depression.

However, mood tracking is no substitute for quality mental healthcare. If a person finds that mood tracking does not help them better control their moods, the support of a therapist or psychiatrist may be necessary. As mental illnesses are medical conditions, an app — even a well-designed one — can only be a useful tool rather than a cure.

Everyone experiences bad moods from time to time. However, when negative moods affect a person’s ability to function, it may be time to seek help. A person should see a doctor or mental health provider if they are:

  • experiencing more bad moods than good ones
  • not seeing improvements after making lifestyle changes
  • experiencing negative moods even after taking medication
  • developing new symptoms with medication
  • having thoughts of suicide or self-harm

Suicide prevention

If you know someone at immediate risk of self-harm, suicide, or hurting another person:

  • Ask the tough question: “Are you considering suicide?”
  • Listen to the person without judgment.
  • Call 911 or the local emergency number, or text TALK to 741741 to communicate with a trained crisis counselor.
  • Stay with the person until professional help arrives.
  • Try to remove any weapons, medications, or other potentially harmful objects if it’s safe to do so.

If you or someone you know is having thoughts of suicide, a prevention hotline can help. The 988 Suicide and Crisis Lifeline is available 24 hours a day at 988. During a crisis, people who are hard of hearing can use their preferred relay service or dial 711 then 988.
