SugarStats is a hawaii-based startup inspired by one diabetics’ unfulfilled need to manage his disease data better. Marston Alfred (the site’s creator) found the online diabetes management solutions boring and inaccessible, so he embarked on crating a clean, user-friendly website where diabetes could track their sugar levels and network with other affected individuals.
They have various analytical graphs and trends, messaging, mobile edition and even twitter integration. I think the concept would have been much more powerful if there was a way to eliminate manual data entry by patients. So integration with blood glucose monitors that can sync data to the website would be great- perhaps using platforms like Healthvault?
Side note: Diabetes is perhaps one of the most well-represented diseases online. There are a ton of resources out there- David Mendosa has a good list here.
