MindShift advertises itself as a free anxiety resource. It offers a wealth of coping skills and supports that anyone can use.

When you sign on to your account, you can track your feeling that day: Awful, Bad, Ok, Good, or Great. This is a bit vague, but this can be helpful for people who might not always have a feeling word for how they are doing.
When you have tracked your feelings for several days, you can review the data to find patterns. You can also learn about different kinds of anxiety, including General Worry, Social Anxiety, Perfectionism, Panic, and Phobias. The app also has tools for changing thought patterns, calming down, and changing behaviors.

The app lets you set goals for yourself and helps you create measurable, attainable goals with specific steps for how you will achieve them. It even prompts you to decide when you think you can reasonable reach your goals!

The blue smiling face at the bottom of the app offers “quick relief” for your anxiety symptoms: Take a breath, Shift your thinking, Ground yourself, Take a small step, and Get help. These quick coping skills can help in a pinch to de-escalate yourself, as well as resources for immediate crisis if you are in the United States or Canada.
If you are dealing with anxiety and need another app in your toolbox, this is a great one to check out.
