Freedive Analytics: Apnea Log

Brauchli Services

About this app

Freedive Analytics is a platform designed specifically for the freediving community. From tracking your deepest descents to planning your next record attempt, get the insights, training tools, and community you need to progress safely and effectively.

Key Features:

🌊 SEAMLESS DIVE WATCH INTEGRATION (.FIT & .UDDF)
• Import directly from Garmin Descent (Mk1/Mk2/Mk3/G1), Suunto (Ocean/D5), Atmos, and more.
• Smart duck-dive detection: Trims surface relaxation automatically so graphs start at your duck dive.
• One-tap mobile share from Garmin Connect or your file browser.

📊 MICRO-LEVEL TELEMETRY, ARM PULLS & FUN STATS
• High-resolution curves for depth, ascent pacing, descent velocity, and water temp.
• Heart Rate & Dive Reflex: Overlay pulse to visualize bradycardia onset under pressure.
• Arm Pull Detection: Biomechanical stroke analysis for FIM and CNF with cadence and trust validation.
• Fun Stats & Scale: Compare depth to landmarks (Eiffel Tower, Pisa) and view Boyle's law lung compression %.
• Interactive velocity smoothing slider to filter out sensor noise.

🤖 SMART COMPARE & AI COACHING
• Companion Suggestions: Instantly recommends matching dives by depth, duration, and water temp.
• Multi-dive profile overlay: Align dives on identical axes to refine freefall depth and pacing.
• AI Coach Scoring: Dynamic 0–100 evaluations across Technique, Pacing, Equalization, and Safety with tailored drills.

⏱️ VOICE-GUIDED STATIC APNEA & HEAT TRAINING
• Classic CO2 and O2 tables plus custom breath-hold intervals.
• Spoken Voice Coaching (TTS): Audio countdowns and contraction cues let you train with your eyes closed.
• Contraction & RPE logging: Track first contraction timing and perceived exertion (1–10).
• Heat & sauna adaptation: Log sauna sessions for plasma volume expansion and hypoxia tolerance.

📸 AI WHITEBOARD & PHOTO WORKOUT PARSER
• Snap a photo of a whiteboard, notebook, or paper workout with your camera, or paste notes.
• Multimodal AI automatically transcribes exercises, sets, reps, and departure times into your calendar.

🇳🇴 NORWEGIAN APNEA METHODOLOGY
• AI-generated sessions based on the 80/20 polarized model (80%+ sub-threshold volume at 45–65% PB).
• Contraction-delay protocols: Finish repeats before contractions begin to train autonomic relaxation.
• Tailored variants for Long Fins, Short Training Fins, or No Fins (DNF/FRC).

📅 TRAINING PLANNER & BUDDY INVITATIONS
• Unified multi-sport calendar for depth sessions, pool apnea, static tables, gym, and habits.
• Buddy Training Invites: Tag dive buddies with instant calendar synchronization upon acceptance.
• Reusable Templates: Save and share favorite workouts via compact fda.li shortlinks.

🎒 EQUIPMENT LOCKER & BUOYANCY TUNING
• Track wetsuits, neck weights, weight belts, bifins, monofins, masks, and nose clips.
• Autocomplete gear tagging and buoyancy correlation to find your neutral buoyancy depth.

👥 COACH HUB & ATHLETE MANAGEMENT
• Real-time coach oversight: Review athlete logbooks, inspect full telemetry, and assign training.
• Persistent athlete context navigation for effortless roster coaching.

🌸 MENSTRUAL CYCLE TRACKING
• Auto-predict cycle phases (Menstrual, Follicular, Ovulatory, Luteal) to correlate performance with hormonal shifts.

🔒 PRIVACY FIRST
Your dives are 100% private by default. Keep them personal, share privately with your coach, or inspire the community.
