App\u2010based technologies permit the collection of real\u2010world data over time and between countries that can help assess true burden of headache. This study used a mobile phone application to collect information on the real\u2010world burden of self\u2010diagnosed headache and to describe its impact on daily life in headache sufferers who do not routinely seek medical advice.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This retrospective, non\u2010interventional, cross\u2010sectional study analysed self\u2010reported data from users of the \u2018Migraine Buddy\u2019 app. The main objective was to describe self\u2010reported characteristics of headache and migraine (triggers, duration, frequency), treatment patterns and impact on daily activity in headache sufferers from Australia, Brazil, France, Germany and Japan. Data including demographics, self\u2010diagnosed episode type (headache\/migraine), duration, potential triggers and impact on daily activity are reported.

Approximately 90% of users were females; &gt;60% were aged 24\u201345\u00a0years. Over one\u2010third of users reported having two to five episodes of headache or migraine per month; impact included impaired concentration, being slower and missing work or social activities. Variations across countries were observed; within countries, episode characteristics were very similar for self\u2010diagnosed headache versus migraine.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Headache tracking was used to describe the experience, impact and self\u2010management approaches of migraine and headache sufferers in a real\u2010world setting.
