Excellent features and very easy to use. Highly recommend. Suggestion for future would be to allow therapy entries to be entered separately from headache entries ie went to the chiropractor today but didnt have a headache. Having some trouble emailing reports. However, overall app is turning out to be a highly effective product for understanding my headache patterns and triggers. Well done!
