About DiveCore: Dive Computer
DiveCore — A real dive computer for Apple Watch Ultra DiveCore harnesses your Apple Watch Ultra's water-resistant depth sensor, compass, and accelerometer to give divers everything they need right on their wrist. 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 with adjustable Gradient Factors - Real-time 16-tissue compartment decompression model - No-decompression limit (NDL) and decompression ceiling - Automatic safety stop countdown (3 min @ 3-6 m, credited with shallow deco stop time) - Ascent rate alarm + haptic warnings - PPO2 oxygen limit alarm - Auto water lock - HealthKit workout session integration - 30Hz smooth digital compass Freediving Mode - Depth disciplines (CWT / CWTB / FIM), static apnea (STA), dynamic apnea (DYN / DNF) - Automatic dive detection for depth, manual timer with lap entry for pool disciplines - Dive count, max depth, surface interval, heart rate, and a per-session log - A session spans many dives: surfacing starts the rest timer, and you end the session yourself - Freedive mode runs no decompression model and no gas or NDL alarms - It cannot detect shallow-water blackout. Never freedive alone, and always dive with direct, trained supervision Estimated Dive Route - Surface GPS captured at entry and exit - Underwater path estimated from compass + gyro + accelerometer + depth changes - End-of-dive drift correction using exit GPS - 3D visualization on iPhone (depth profile walls, drag-to-rotate, pinch-to-zoom) - Insights: average speed, activity level, exploration pattern, current drift estimation This is not real underwater GPS tracking. It is a sensor-fusion estimate based on the diver's magnetic heading and motion, with both endpoints corrected by surface GPS fixes. No-Fly Timer (Live Activity) - DAN/UHMS guideline tiers (12h single no-deco / 18h repetitive or multi-day / 24h decompression), never shortened by a later dive - Lock-screen + Dynamic Island countdown AI Analysis (XAI — Explainable) - 100% on-device, no external API calls - Dive score (0-100) with an itemized breakdown of penalties and bonuses - Real-time Risk Index and automatic stress zone detection - Personal baseline learning Dive Log + Share - iCloud automatic sync across devices - Auto-recorded: water temp, gas mix, SAC, tank pressure, algorithm, no-fly time - Infographic share card, 1080x1350 - Entry/exit coordinates open in Apple Maps DiveCore Studio (Photo Editor) - Underwater color correction, depth-based red channel restoration, AI dehaze - Dive log watermark Watch Display Customization - Technical bottom bar: choose what it shows, including heading (HDG) - Minimal: 3 configurable bottom-card slots and MAX ring field (dive time, avg/max depth, water temp, HR, GF) iPhone Companion - Detailed dive log with depth profile chart - PADI RDP dive planner, AI report, dive site location, statistics, iCloud backup [ Required Hardware ] - Apple Watch Ultra (1st generation or later) - iPhone with iOS 18+ - iCloud account + Apple Sign-In [ Accessibility ] - VoiceOver support and Dynamic Type - 14 languages [ Subscription Terms ] - DiveCore Pro (choose one; all unlock the full feature set): - Yearly: $29.99/year (KRW 44,000) - includes a 7-day free trial for new subscribers - Monthly: $4.99/month (KRW 7,700) - no free trial - 1-Day Pass: $2.99 (KRW 3,300) - 24-hour access, non-renewing (does not auto-renew) - Local currency may apply; prices are set per storefront. - Payment is charged to your Apple ID account at confirmation of purchase - Yearly and Monthly auto-renew unless cancelled at least 24 hours before the end of the current period - If not cancelled at least 24 hours before the trial ends, you will be charged automatically - Manage or cancel your subscription anytime in your device's App Store account settings - Terms of Use (EULA): https://furyus.dev/terms
What’s new
Version 2.2.1 · Updated October 10, 2026
v2.2.1 Update · On Apple Watch, below 6 m the last measured depth stays on screen between readings; "NO DEPTH SENSOR" appears only after a long gap with no new reading · The "workout failed" message no longer appears when a dive starts · Freediving: dives below 6 m keep recording the depth the watch receives instead of stopping at 6 m · After decompression stops, time at the shallow stops (1.5 to 6 m) counts toward the 3-minute safety stop
