Phone Sensors
An Energy Score Built From the Phone You Carry
An energy score app based on phone sensors is for people who want a readiness-style number without a strap. MaxDex estimates capacity from on-device sleep and movement, then uses it in planning.
What the phone can honestly measure
Steps from the device IMU, sleep from inactivity and movement patterns, optional meal logs. That is not HRV from a chest strap. It is enough to stop treating every hour as equal.
Sleep, steps, and food as one picture
People search track energy levels based on sleep steps food because isolated graphs do not change the calendar. MaxDex keeps those inputs on the device and feeds the day plan.
Score → schedule → call
A number that does not change behavior is a widget. The energy score should resize work and change what the morning call emphasizes.
