Wearable-Free Energy Tracking
Track Sleep Debt & Daily Energy Phone-Only
You should not need a ring, band, or watch to know whether today is a high-output day or a recovery day. MaxDex is a sleep tracker without a smartwatch: phone sensors plus simple inputs estimate sleep, movement, and energy so planning can follow capacity.
Hardware-Free Sleep Monitoring
MaxDex estimates sleep from on-device inactivity and movement patterns. Hours and rhythm stay on your phone. This is not a clinical sleep study and it is not a hardware-grade Whoop or Oura clone. It is a practical sleep debt tracker for people who want software-only awareness.
If you have been comparing an Oura ring alternative software only, a Whoop alternative without hardware, or how to track sleep debt without an Apple Watch, the job to be done is the same: know when you are running a deficit before you overload the calendar.
Measuring Afternoon Dips via Phone Signals
Energy is not a vibe. It is a pattern: last night’s sleep, today’s movement, and how you have been stacking recovery. MaxDex surfaces those patterns so the 2 p.m. crash is visible instead of surprising.
You can log meals and activity on the phone as well. The point is not a calorie-deficit diet product. The point is a daily energy tracking app without Oura-style hardware, so you stop planning a peak-focus afternoon on a sleep-debt morning.
Aligning Tasks to Energy Scores
A readiness-style score is only useful if it changes what you do next. MaxDex connects phone-only energy tracking to the daily planner: high-friction work when capacity is there, admin and recovery when it is not.
That is the gap hardware brands leave open. They sell the metric. MaxDex uses the metric to time check-in calls and reshape the day.
