DiveCore vs Dive Toolbox

DiveCore — Dive Computer for Apple Watch Ultra DiveCore uses your Apple Watch Ultra's depth sensor, compass, and accelerometer to show your dive on your wrist. It syncs with the iPhone companion app and uses on-device AI to help you review your dives. [ 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 at entry and exit; underwater path estimated from compass, motion and depth, then drift-corrected with the exit fix - 3D route view on iPhone with insights (speed, activity, pattern, current drift) 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 itemized breakdown, stress zones and personal baseline Dive Log + Share - iCloud automatic sync across devices - Logs water temp, gas mix, algorithm, no-fly time; SAC and end pressure are estimated - Infographic share card; entry/exit points 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 (incl. heading), Minimal card slots and MAX ring field 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) - Prices may vary by storefront and currency. - 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 - Privacy Policy: https://furyus.dev/privacy IMPORTANT SAFETY INFORMATION DiveCore is a supplementary tool for trained, certified divers. It is not a replacement for proper training, dive tables, or a backup dive computer. Always dive within the limits of your training and certification, follow your primary dive computer, and carry a redundant device. Diving carries inherent risks, including serious injury or death.

DiveToolbox — Professional dive planning and gas calculation tools for recreational and technical divers. DECOMPRESSION DIVE PLANNER Plan single-level and multi-level dives using the Bühlmann ZH-L16C algorithm with configurable gradient factors. Get detailed ascent profiles, gas switch schedules, and comprehensive safety analysis including CNS, OTU, gas density, and END monitoring. GAS BLENDING CALCULATOR Step-by-step fill instructions for Nitrox and Trimix blending. Supports partial pressure and continuous flow methods with real-time MOD calculations. MOD / EAD / END CALCULATOR Instantly calculate Maximum Operating Depth, Equivalent Air Depth, and Equivalent Narcotic Depth for any gas mix. GRADIENT FACTORS EXPLORER Visualize how GF Low and GF High affect no-decompression limits and decompression schedules. SAC RATE CALCULATOR Calculate your Surface Air Consumption rate from dive data to improve gas planning accuracy. ROCK BOTTOM CALCULATOR Determine minimum gas reserves for safe ascent, including emergency scenarios with configurable safety margins. SUCCESSIVE DIVE PLANNER Plan repetitive dives accounting for residual nitrogen and helium tissue loading from previous dives. UNIT CONVERSIONS Convert between metric and imperial units for depth, pressure, volume, and temperature. KEY FEATURES • Multi-gas support with automatic deco gas switching • Save and organize dive plans in folders • Save tank presets for quick planning • Share plans via link or QR code • Export plans as PDF • Customizable diver profile (GF, SAC, PPO2, speeds) • Dark and light themes • Available in 7 languages: English, French, German, Spanish, Italian, Polish, Russian Terms of Use: https://divetoolbox.com/en/terms Privacy Policy: https://divetoolbox.com/en/privacy
