Half-Life: Substance Telemetry

Stop guessing when your supplements kick in. Half-Life brings real-time pharmacokinetic telemetry to your training, focus, and recovery. Most supplement apps are basic reminders. Half-Life is an engine that models blood plasma concentration curves in real-time. Whether you are timing a high-stim pre-workout for maximal vasodilation or calculating caffeine clearance before bedtime, Half-Life gives you continuous physiological visibility. KEY FEATURES • REAL-TIME COCKPIT TELEMETRY Visualize continuous absorption and elimination curves across four primary bio-pathways: CNS Drive, Nitric Oxide (Pump), Cellular Fuel, and Recovery. Drag across the chart to inspect your exact circulating levels at any minute of the day. • CHRONO-PLANNER: PEAK AT WORKOUT START Tell Half-Life when you start lifting. The algorithm calculates your staggered ingestion schedule so vasodilators (Citrulline ~60m), stimulants (Caffeine ~45m), and neuromuscular buffers (Beta-Alanine ~30m) peak simultaneously on your first working set. • DEEP SLEEP PROTECTION Caffeine has a ~5-hour half-life. 200mg at 3 PM leaves ~50mg in your system at 1 AM, degrading deep restorative slow-wave sleep. Half-Life projects your clearance curve against your target bedtime with real-time threshold warnings. • STACK LAB & SYNERGY DETECTION Build custom multi-compound stacks or use evidence-based presets (Clean Focus, Nitric Pump, Deep Recovery, Pre-Workout). Get automatic alerts for concurrent vasodilators, excessive stimulant load, or late evening dosing. • COMPLETE PRIVACY BY DESIGN Your health and supplementation data belongs exclusively to you. No account required, no ads, no trackers, and zero cloud transmission. All logs are stored securely on your device with SwiftData. EDUCATIONAL & MEDICAL DISCLAIMER Half-Life is an educational and informational simulator that models typical pharmacokinetic curves based on published scientific literature.
