Has regular access to the Internet via cellular data plan and/or wifi. Exclusion Criteria: A participant will not be eligible for study entry if any of the following criteria are met: History of basilar migraine or hemiplegic migraine. Active chronic pain syndromes, such as fibromyalgia, chronic pelvic pain, or complex regional pain syndrome (CRPS). Other pain syndromes (including trigeminal neuralgia), psychiatric conditions (such as major depressive episode, bipolar disorder, major depressive disorder, schizophrenia), dementia, or significant neurological disorders (other than migraine) that, in the Investigator's opinion, might interfere with study assessments. History of, treatment for, or evidence of, alcohol or drug abuse within the past 12 months (48 weeks) or having met DSM-V criteria for any significant substance use disorder within the past 12 months (48 weeks) from the date of the screening visit.

Currently taking a prescription anti-calcitonin gene-related peptide (CGRP) for either episodic or chronic migraine. Post-traumatic headache, persistent post-traumatic headache, or post-concussion syndrome. Other significant episodic or chronic medical condition(s) that in the opinion of the Investigator, may confound the interpretation of findings to inform PDT development. Failure to adhere with or inability to complete Study App inputs and onboarding activities during the run-in period. Participants who are not adherent during the run-in period are not eligible for study entry. Previous enrollment in any digital therapeutics pilot or pivotal study for a migraine indication.
