Good log - cant email

This app works well for logging blood sugars, meals, weight, and meds. Also provides graphs to review trends, and can set alerts for your own custom measures based on timing of blood sugar monitoring.
However, I am unable to export logs via email. Without this function, the app is essentially useless as it makes it much more difficult to share the information with my provider.
I have tried to contact the developer/provide app feedback twice without any response.
