achu is the first ever sickness tracking and predicting mobile app made for use with fitbit bracelets. achu is designed to predict if a user will get a cold by analyzing the day to day patterns in their fitbit data. achu uses a pattern recognition algorithm to give users health predictions based on their past and present data.

In order for achu to know what health patterns constitute for the user being sick, the user must first calibrate the app by entering that they are in fact sick. Once the user calibrates the app with a sickness, achu will begin to look for similar trends and patterns that match the sequence of data in the aforementioned sickness calibration. The user can calibrate achu with as many sicknesses as they like and achu will generate a unique algorithm for each of them.

Take control of your reoccurring symptoms by letting achu track them and predict the likelihood of them happening again so you can proactively defend against them. Once installed and calibrated, achu will notify you each day on the probability of getting sick!
