Subjects assigned to this arm will not be offered access to the mobile app during the first 8 weeks of their participation. Subjects will be asked to begin using the app eight weeks after randomization. Subjects assigned to this arm will complete a questionnaire at three times points: the beginning after the subject has signed the informed consent form, at the 8 week time point (just before subject begins using the mobile app) and 16 week time point.

Subjects assigned to this arm will receive mindfulness meditation instructions for 8 consecutive weeks following randomization to this arm. The mobile app contains 14 sessions that subject can participate in at their own pace. Subjects are asked to try and practice mindfulness meditation daily, for a total time of 2 hours per week. Subjects assigned to this arm will complete a questionnaire at three times points: the beginning after the subject has signed the informed consent form, at the 8 week and 16 week time points.

It is hypothesized that participants who are randomized in the app condition will have significantly less anxiety, pain, fatigue, and sleep disturbance than their counterparts in the control condition.

Anxiety will be measured with the GAD-7, which entails respondents indicating how much in the past week they experienced anxiety. Participants are asked to provide their responses on a 5-point Likert type scale, with options ranging from "never" to "always."

Pain will be measured with the PEG-3, a three item measure assessing pain intensity, interference with general activity, and interference with enjoyment of life, with response options ranging from a 0-10 scale (0 being "no pain" or "does not interfere" and 10 being "pains as bad as you can imagine" or "completely interferes").

Fatigue will be measured with the Brief Fatigue Inventory, a 9-item measure where respondents are asked to rate their fatigue on an 11-point scale, with options on three items ranging from either "no fatigue" to "as bad as you can imagine" and options on the remaining items ranging from "does not interfere" to "completely interferes"

Trauma Symptoms will be measured with the PCL-5. This 20-item measure assess for the 20 DSM-5 symptoms of PTSD, which fit into the larger categories of intrusive and avoidant symptoms.

Sleep will be measured by the PROMIS sleep scale, an 8-item measure, with 5-point response choices.

Patient self-reporting through the Mobile Mindful Meditation platform will measure satisfaction via the Five Facet Mindfulness Questionnaire. Successfully completing the 8-week program will also be an indirect measure of patient satisfaction.
