Migraines really, really suck, and treating them is difficult due to the fact that we really aren’t sure what causes them. Fortunately for sufferers of this disease, migraines can still be prevented in most cases and a startup out of Singapore known as Healint has a mobile app that can help you do just that. Using various sensor readings, the app is able to predict when users will have a migraine with somewhere around 90% accuracy and can use this information to help them understand the disease.
