Excellent symptom tracker
For us self diagnosing types and for those trying to unearth the causes for a syndrome or interaction of factors and symptoms, this is a great tracking app that should address nearly all your needs.
Id love to see a simple implementation of the tracker for Apple Watch, and it would be great if it imported/exported data from HealthKit, and it would be great if there were some smarts behind the data to unearth the more complex statistical relationships between factors.
