You have a number. You might not like it. Sleep Toll reads your Apple Health sleep data and calculates one thing: how many hours of sleep you owe your body. Not an estimate. Not a score. A measurement — cold, cumulative, and precise. This is not a wellness app. There are no soothing sounds, no bedtime reminders, no congratulations for sleeping adequately. Sleep Toll exists to confront you with the toll your habits have taken. WHAT SLEEP TOLL DOES • Reads your sleep data directly from Apple HealthKit • Calculates your cumulative sleep debt over a rolling 4-week window • Compares your actual sleep against your biological need • Presents the result as a single, unambiguous number THE NUMBER Your sleep debt is displayed in hours — the gap between what you got and what you needed. The number grows when you undersleep. It shrinks when you recover. It never lies. The interface shifts in severity as your debt climbs. Low debt is quiet. High debt demands attention. The design does not let you look away. SEVERITY LEVELS Sleep Toll assigns a severity level to your debt, from minimal to critical. Each level changes the visual tone of the app — colors, typography weight, and urgency all respond to how deep in debt you are. You'll know at a glance whether you're coasting or drowning. SHARE YOUR TOLL Your sleep debt number is designed to be shared. Generate a dark, clinical share card showing your exact debt and severity level. Post it, text it, or keep it as a private reminder. The number speaks for itself. WEEKLY TRENDS Track how your debt moves over time. See your 4-week trajectory — are you digging deeper, or climbing out? Weekly breakdowns show exactly when the damage happened. WIDGETS Put your sleep debt on your home screen or lock screen. A small widget shows the number. A medium widget adds your trend. No hiding from it. PREMIUM Sleep Toll is free at its core. The number, the severity, and the share card are yours — no paywall. Premium unlocks deeper analysis: • Detailed daily breakdowns • Extended trend history • Advanced share card styles • Priority support Your sleep data never leaves your device. Sleep Toll reads from HealthKit and calculates locally. No accounts, no cloud sync, no data collection. Your debt is your business. Sleep Toll doesn't help you sleep better. It shows you what happens when you don't. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
