Apnio is your personal freediving and apnea training companion, designed for beginners and experienced freedivers alike. SCIENTIFIC TRAINING METHODS Train with proven techniques used by professional freedivers: • O2 Tables — Build oxygen tolerance with progressive breath-hold intervals • CO2 Tables — Build CO2 tolerance with fixed holds and shorter rests • Custom Tables — Design and save your own breath-hold sequences • Square Breathing — Guided breathing exercises to calm your nervous system • Personalized Plans — Smart training plans tailored to your level and goals DIVE LOG Log every dive with location, depth, conditions, and notes. Attach photos and videos, tag your dive sites on the map, and track your SpO2 (blood oxygen) readings over time. Tap any photo for a full-screen view. PROGRESS & HISTORY See your improvement at a glance — streaks, personal bests, weekly trends, and total training time. Browse every past session on a calendar and revisit your training history anytime. APPLE WATCH INTEGRATION Run training sessions right from your wrist. Track heart rate during breath-holds with HealthKit, start and stop sessions independently, and stay in sync with your iPhone automatically. SAFETY FIRST Apnio is a training tool, not a substitute for supervised freediving instruction. Never practice breath-holding alone, especially in or near water. Whether you're preparing for your first static breath-hold or training for competition, Apnio gives you the structure, tracking, and tools to dive deeper, longer, and safer.
