DiveCore A real dive computer for Apple Watch Ultra

DiveCore turns your Apple Watch Ultra into a full-featured dive computer. Using the water-resistant depth sensor, compass, and accelerometer, it pairs with the iPhone companion app in real time and uses on-device AI to help you improve your dive patterns.

[ Core Features ]

Dive Computer (Apple Watch Ultra)

• Bühlmann ZHL-16C decompression model with adjustable Gradient Factors
• Real-time 16-tissue compartment computation
• NDL + decompression ceiling display
• Auto safety stop countdown (3 min @ 3-6 m)
• Ascent rate + PPO2 alarms with haptic feedback
• Auto water lock
• HealthKit dive workout integration
• 60Hz smooth digital compass

Estimated Dive Route GPS captured at entry/exit; underwater path estimated from compass + gyro + accelerometer + depth, with drift correction at exit. 3D visualization on iPhone with playback (30/60/120/240x speed) and insights (average speed, activity level, exploration pattern, current drift). This is a sensor-fusion estimate, not real underwater GPS tracking.

No-Fly Timer DAN/UHMS guideline + cumulative tissue load model. Lock-screen and Dynamic Island Live Activity with airplane countdown.

AI Analysis (Explainable, on-device) 100% on-device — no external API. Dive score (0-100) with breakdown across Safety, Efficiency, Consistency, Condition, and Depth Management. Real-time Risk Index with automatic stress-zone detection (HR spikes, rapid ascent, NDL approach, cold exposure, depth oscillation). Personal baseline learning.

Dive Log + Share iCloud auto-sync. Water temp, gas mix, SAC, tank pressure, algorithm, and no-fly time auto-recorded. Customizable 1080x1350 infographic share card. Entry/exit coordinates open in Apple Maps.

DiveCore Studio (Photo Editor) Underwater color correction (Auto / Manual), depth-based red channel restoration, AI dehaze, optional dive log watermark.

Watch Display Customization 6 readability-tested color presets (Classic Dark, Ocean, Sunset, Night Dive, Tech, High Contrast). 3 freely configurable bottom-card slots (water temp / avg depth / heart rate / SAC / safety stop / GF). MAX ring field selection.

iPhone Companion Detailed dive log with depth profile chart, AI report, dive site reverse-geocoding, statistics dashboard, iCloud backup.

[ Required Hardware ] Apple Watch Ultra (1st gen or later), iPhone with iOS 18+, iCloud account + Apple Sign-In.

[ Accessibility ] VoiceOver, Dynamic Type, Korean / English.

[ Safety Disclaimer ] DiveCore is an assistance tool. Diving must only be performed by certified divers trained by qualified instructors. Do not rely solely on a dive computer. Always dive with a buddy, follow conservative profiles, and complete safety stops.
