● Problem ● Our Solution ● Market Solution ● Constraints ○ Technical ○ Practical ● Approach ● Progress ● Timeline Topics

Problem ● Cost effective fitness band ● The SMART Band should not be too complex ● Creating a device that will compete with similar devices i.e. Fitbit, Tom Tom Runner ● Create a product that is different from gadgets already on the market

Our Solution ● easy to use ● affordable ● rechargeable ● counts steps taken ● location services ● pulse reading ● temperature sensing ● storage of data ● Graphical User Interface (GUI) for customization and data dump ● ability to track trends

● Similar products already on the market ○ Apple Watch ○ Fitbit ○ Tom Tom Runner Cardio Market Solution

Similar ProductsWhat they offerWhat SMART BAND offers Apple Watch Goals for workouts Workout Applications Heart Rate monitor Mainly a phone on your wrist GUI to track progress and customize GPS for tracking Pedometer for step count Pulse sensor Ambient Temperature Sensor Fitbit Different devices for different ablilties Basic model only offers steps, calories, and distance Have to spend more for more options All options/sensors offered on one device at one price Tom Tom Runner Cardio GPS Heart rate monitor Workout application GUI to track progress and customize GPS for tracking Pedometer for step count Pulse sensor Ambient Temperature Sensor
