Headache Relief is a new iPhone app which I developed to help patients better manage their headaches.  The main feature of the app is a headache diary.  A summary of all your diary entries can be emailed to yourself or your doctor in an Excel spreadsheet form.  I find that patients who keep a diary benefit from it in many ways.  The diary makes it easier to figure out what may be causing your headaches, how well the treatment works, and allows you to better control your headaches.  The potential triggers that are recorded in the diary include stress, menstrual cycle, food, sleep, and other.  Weather can be a major contributor and the three most common weather-related triggers are temperature, humidity and barometric pressure.  A unique (and very neat) feature of this app is that if you to enter your zip code these three weather parameters will be downloaded into your diary.  The app also contains an e-book with a wealth of information on headaches, natural and pharmacological therapies.  And the price is right – it’s free.  Please let me know what you think or better still, post your evaluations on the iTunes store.
