Sleep-2-Peak is a highly sensitive scientific tool developed by sleep specialists that will show you your best sleep and work/activity schedule by measuring your alertness variations. No other device or wearable required. Figure out your unique circadian rhythm and how to be most alert during the day. Use sleep-2-Peak to demonstrate to others your sleep need and ideal work/activity schedule contributing to your wellbeing. Your alertness variations are measured with a scientifically validated, short and simple reaction time test and/or through Text-Speed able to track your texting speed variations (patent pending). Your results are linked to your previous night bedtime/out of bed time to see what sleep schedule allows YOU to be at your BEST the next day. Your reaction time variations throughout the day are also demonstrated on a second graph to see what time of day is associated to your best performances. Ideal for high performance athletes, executives, and anyone else who wants to know the best time to sleep, workout, and even engage in analytical and creative activities. Researchers can also use sleep-2-Peak in their studies of fatigue and alertness as its reaction time test is proven to be as sensitive as the widely used PVT or even more sensitive for some aspects (sleep-2-Peak compared to the gold standard PVT-192). It is also more practical as every subject can have their own measuring device and transfer their data if desired to the researcher. Developed by a neurologist specialized in sleep medicine, cognitive psychologists with expertise in sleep and alertness and experts in digital health. Our fatigue measurement reaction time task is scientifically validated in a peer reviewed publication: Brunet, J. F., Dagenais, D., Therrien, M., Gartenberg, D., & Forest, G. (2017). Validation of sleep-2-Peak: A smartphone application that can detect fatigue-related changes in reaction times during sleep deprivation. Behavior Research Methods, 49, 2, 1460-1469. >10 poster publications that validate the use of the app for measuring physical and cognitive states. Your data is YOURS. You can export your data to your computer and select data you would like to export to others. Your data could also contribute to a global database to allow a better understanding of circadian rhythms and what can be done to improve schedules and wellbeing. In this event, your permission will be required to have your data entered in the database. The application was developed to be sensitive to detect: - Sleep need - The circadian rhythm (alertness variation with time of day and body rhythms) - Mental and physical performance variation (correlation with reaction time test) - Influence of substances By using sleep-2-Peak, you will become aware of alertness variations beyond what you can feel. You will discover how powerful your schedule choices can be to boost your performances naturally.

PRECISION. PERFORMANCE. PROTECTION. PilotPeak is the advanced Fatigue Risk Management System (FRMS) engineered for the modern aviation professional. Bridging the gap between regulatory limitations and human physiology, PilotPeak empowers pilots with data-driven situational awareness. Designed for high-reliability environments, our platform integrates proprietary biomathematical models with Apple HealthKit data to provide a comprehensive analysis of your fitness for duty. THE PILOTPEAK ADVANTAGE: Enterprise-Grade Fatigue Analytics Move beyond simple flight time limitations. Our "Bio-Metric Engine" processes sleep quality, Heart Rate Variability (HRV), and circadian rhythms to visualize your Alertness Index. Anticipate performance dips before they occur. Secure & Anonymised Data Architecture. PilotPeak employs enterprise-grade data handling protocols. While the system processes biometric and operational data to generate analytics, all processing is performed using de-identified methodologies. Your fatigue metrics are utilized strictly for analytical performance and are never linked to your personal identity or user profile on our servers. Intelligent Roster Digitization (OCR) Streamline your administration. Our advanced Optical Character Recognition (OCR) module instantly converts physical and digital rosters into actionable data—automatically logging Flight Duty Periods (FDP), Block Times, and Rest intervals. Microsleep Risk Assessment Utilizing probabilistic modeling, the system identifies patterns correlated with lowered alertness states. This predictive layer supports your decision-making for strategic caffeine intake or controlled rest planning. GLOBAL COMPLIANCE SUPPORT: • Digital Logbook: Generates reports compatible with FAA, EASA, and ICAO formatting standards (PDF/CSV). • Currency & Type Rating: Automated tracking for validity and recency requirements. • Faith & Flight: Integrated high-precision prayer times and Qibla direction for global operations. • Offline Sovereignty: Full analytical capabilities at 40,000 ft without internet dependency. CRITICAL OPERATIONAL DISCLAIMERS NON-MEDICAL DEVICE PilotPeak is a data visualization and tracking utility. It is NOT a medical device and is NOT intended for the diagnosis, cure, mitigation, treatment, or prevention of any disease or medical condition. The "Alertness Index" and "Microsleep Risk" are probabilistic estimates for educational purposes only. REGULATORY STATUS PilotPeak is an independent support tool and is NOT certified by the FAA, EASA, ICAO, or any aviation authority as an official Flight Time Limitation (FTL) calculator. It does not replace your operator’s approved Operations Manual (OM/A) or official rostering system. PILOT IN COMMAND RESPONSIBILITY The user assumes full responsibility for all "Fitness to Fly" decisions. Compliance with applicable aviation regulations (e.g., FAR Part 117, EASA ORO.FTL) remains the sole obligation of the pilot. Do not rely exclusively on this application for safety-critical decisions. LIMITATION OF LIABILITY By using this platform, you acknowledge that PilotPeak and its developers are not liable for any direct or indirect consequences arising from the use of this software, including but not limited to operational incidents, regulatory fines, or scheduling errors.
