PilotSense is a science-backed fatigue management platform for pilots and flight organizations. Get a readiness score before every flight based on your sleep, reaction time, circadian rhythm, and biometrics — grounded in validated aviation research. HOW IT WORKS Complete a quick daily check-in combining: Apple Health sleep data (duration, efficiency, fragmentation) Psychomotor Vigilance Test (PVT-B) — the gold standard for measuring alertness, available in 30-second screening or 3-minute validated modes Karolinska Sleepiness Scale (KSS) self-assessment Circadian phase and jetlag tracking Wearable biometrics (HRV, resting heart rate, respiratory rate) Your readiness score is computed using peer-reviewed fatigue science frameworks published by the FAA (AC 120-103A) and EASA (ORO.FTL.120), with transparent weighting: Sleep 47%, Circadian 22%, PVT 22%, KSS 9%. FIVE-BAND READINESS SYSTEM SHARP (88–100) — Peak alertness READY (75–87) — Good to go CAUTION (55–74) — Fly with awareness ELEVATED (35–54) — Reconsider if possible REST (0–34) — Do not fly PRE-FLIGHT BRIEF Integrated decision support covering pilot readiness, weather (live METAR/TAF), currency compliance, aircraft status, and environmental factors — all on one screen. IN-FLIGHT MONITORING Minimal, glanceable alerts during flight. One-tap "I'm feeling tired" button with tailored countermeasure recommendations. Window of Circadian Low (WOCL) warnings when your body clock dips. SAFETY TOOLS BAC Calculator — Widmark formula with 8-hour bottle-to-throttle enforcement (14 CFR 91.17) FAA Medication Database — 2000+ drugs with impairment classification Digital Logbook — GPS auto-detect takeoff, auto-log from scheduled flights, export to CSV/PDF Circadian & Jetlag Tracker — Know your body clock before you fly Currency Tracking — §61.57 day/night/instrument currency, medical, and BFR monitoring FOR FLIGHT SCHOOLS & ORGANIZATIONS Admin dashboard with real-time fleet oversight: Fleet readiness distribution — see your organization's safety posture at a glance Time-sensitive safety alerts when a pilot checks in at risk with a flight scheduled Check-in monitoring and missed check-in alerts Safety override logging Instructor-student management with solo endorsements Privacy-first: pilots control what data their organization sees through three tiers (Status Only, Score, Full Details) BUILT ON SCIENCE Every score is informed by peer-reviewed aviation fatigue research including Basner & Dinges (2011), Van Dongen et al. (2004), Dawson & Reid (1997), and FAA/EASA fatigue risk management frameworks. PilotSense is a screening-grade decision-support tool, not a certified FRMS or medical device. PRIVACY BY DESIGN Mental wellness screenings stay between you and the app — never shared with organizations at any tier Pilots choose their privacy tier — admins see fleet aggregates and safety escalations by default, not individual health data Raw sleep, KSS, and self-report data stays private unless you opt into Full Details No tracking, no ads, no data sold Free for all pilots. No subscriptions. No paywalls.

Verdict
The clearest difference is in-app purchases: PilotSense at none against CaffeineLog's 2. CaffeineLog's advantage is update cadence (every 2 days vs fortnightly) and iOS requirement (17.0 vs 26.2). On price, ads and device support there is nothing between them.
