FROM (www.misu.app/how-misu-works ):
Throughout the day, Misu automatically tracks your happiness and anxiety index (0-100) dozens of times intermittently. This is done through an emotion detection AI that detects mood through facial micro expressions (such as subtle eye squinting or frowning).
We trained the emotion detection AI from a manual mood tracker we built used by ¼ million people. We asked some of them if we could take photos in the background when they logged their self-reported levels of happiness and anxiety. Thousands of people opted-in (thank you all!) and did this 500k times, giving us sufficient data to train our emotion detection model. More Info »
In Misu, camera data is never sent to our servers, stored, or shared, and photos are deleted immediately after your emotional state is calculated. We take your privacy seriously, read more about it here.
Misu shares this information back to you, making it easy to reflect on your mood throughout the day, and over the past few days, weeks and months.
We’re working to build you the best mood tracker around, helping you become happier and less anxious is what we strive for. If you have any feedback, email Dan (email@example.com).
