DiveCore vs DivePlot

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) - 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 breakdown (Safety, Efficiency, Consistency, Condition, Depth Management) - 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 - 6 readability-tested color presets - 3 configurable bottom-card slots and MAX ring field selection 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

Turn your dive computer log into a beautiful photo overlay. DivePlot reads a dive straight from your dive computer over Bluetooth and turns it into a clean, professional overlay: your depth profile as a graph, live readouts like a dive computer, or both — on top of your own dive photo or as a transparent PNG for your video editor. How it works 1. Connect your dive computer and pick one of your latest dives. 2. Style your overlay: graph lines, colors, line thickness, text fields and a legend. 3. Export to your photo album or share it directly. Overlay studio • Depth, temperature, deco, pO₂ and tank pressure as graph lines — each with its own color and toggle • Dive computer mode: replay your dive with live depth, time, pO₂, temperature, CNS and tank pressure readouts • Scrub to any moment of the dive — the readouts follow • Add your own photo as background, with zoom, pan, dim and blur • Effects below the depth line: darken, grayscale or blur • Draggable text fields (depth, duration, date, time, your name) with size, color, alignment and outline • Legend, line thickness slider and multiple export formats: 16:9, 4:3, 9:16, 3:4, 1:1 and 4:5 • Save your favorite designs and reuse them on the next dive • No photo? Export a transparent PNG to use as an overlay in any video editor Supported dive computers DivePlot connects to the Halcyon Symbios (handset and HUD) over Bluetooth and downloads your most recent dives — including rebreather data such as cell pO₂ and tank pressure. Support for more brands is in the works. No account, no ads, no tracking. Your dives stay on your device. Free version adds a small "created with DivePlot app" watermark; a one-time purchase removes it.
