SleepDebtTracker: Cumulative Sleep Deficit Monitor
Tracks sleep debt across weeks and predicts cognitive/health decline for sleep-deprived professionals who need to understand their accumulated deficit, not just last night's hours.
The Problem
People focus on individual night's sleep quality but ignore cumulative sleep debt—the compound effect of chronic under-sleeping. Most sleep apps show yesterday's data, not the dangerous pattern of 5-6 hour nights adding up. Knowledge workers don't connect their foggy decisions, mood crashes, or illness to accumulated sleep deficit.
Target Audience
Overworked professionals (tech workers, consultants, startup founders), shift workers, medical residents—people chronically sleeping 5-7 hours who want objective proof sleep debt is hurting them.
Why Now?
Sleep-tracking hardware (Oura Ring, smartwatches) are ubiquitous, but no app translates raw data into actionable cumulative insights; wellness budgets are expanding post-burnout culture.
What's Missing
Existing sleep apps optimize for single-night improvements but ignore the compounding deficit model that actually drives health outcomes. No app quantifies 'you're down 14 hours this week' or predicts 'your decision-making will drop 23% by Friday.'
