What's New in DiveCore

2.0.2

September 19, 2026

v2.0.2 Update - Apple Watch: nitrogen loading during a lost-sensor hold is now applied when the dive ends, so no-fly time and the next dive's no-decompression limit are calculated more conservatively - Apple Watch: NDL stays on screen during decompression and the stop is shown in one place (STOP AT). Crossing the ascent ceiling now shows CEILING ↓ - Apple Watch: fixed surface pressure staying at sea level after an underwater restart on altitude dives - Apple Watch: the Minimal layout now shows sensor lost and sensor delay states - iPhone: the Dive Display settings show a preview of your watch screen - iPhone: dive logs without a recorded end pressure can now be edited and saved, and dates in the log list are no longer cut off - iPhone: emergency numbers in international format (+) now dial correctly, and subscription details are no longer shown incorrectly during the free promotion - General stability and UI refinements (Previous) v2.0.1 Update - Scuba on Apple Watch: at the surface, releasing Water Lock with the Digital Crown now ends the dive, as does about 2 minutes out of the water. The countdown that reopened each time your wrist left the water is gone. Doesn't apply underwater, in freediving or with a decompression obligation - Fixed false "NO DEPTH SENSOR" warnings below 6 m, at a 5 m stop, on repeat dives and after leaving the water - Depth sensor lost: the Action Button now shows the instruments while the warning continues. SENSOR DELAY now appears on the default screen - Fixed an OK summary after surfacing with a decompression obligation, and sea-level pressure on altitude dives started straight from Ready - Freediving: at the surface under Water Lock, press the Action Button twice to end a depth session. Instrument labels are now localized - Logged water temperature and the low-temperature alarm now use sensor readings only - iPhone: the depth profile and exit location sent after each dive now reach iCloud backup - Planner tank warnings no longer count the gas reserve twice; AI dive reports use your real surface interval - The emergency number follows your iPhone's region; Studio's dive log watermark no longer adds your location - General stability and UI refinements (Previous) v2.0 Update - New freediving mode: depth disciplines (CWT/CWTB/FIM), static apnea (STA) and dynamic apnea (DYN/DNF), recording dive count, max depth, surface interval and heart rate - A new freediving instrument screen. Turn the Digital Crown through three instrument pages plus a control page; each discipline has its own colour - A freediving session does not end when you surface. It keeps recording across dives and rest, and releasing Water Lock with the Digital Crown asks whether you are finished - Freedive mode runs no decompression model and no gas or NDL alarms. Please read and accept the updated safety notice — this app cannot detect shallow-water blackout. Never freedive alone - Entering freedive mode soon after a scuba dive now tells you that you still carry residual nitrogen - The Apple Watch scuba dive screen was redesigned: pure black with hairline dividers and five Crown pages (hero, compass, stop guidance, info list, gas/tank) - Fixed a bug where relaunching the app during a dive showed "depth sensor not supported" and left the app unusable - Fixed the decompression first-stop reference so the plan the app gives you no longer trips the app's own ceiling alarm - Corrected display and stepping for yard pools and feet depth settings - General stability and UI refinements

다이빙하면서 사용해보았는데 전체적으로 편의성이 정말 좋았습니다. 처음 실행했을 때부터 화면 구성이 깔끔하고 복잡하지 않아서 필요한 기능을 바로 찾을 수 있었어요. 메뉴 이동도 직관적이라 처음 사용하는 사람도 크게 어렵지 않게 사용할 수 있을 것 같습니다.

특히 다이빙할 때 확인해야 하는 정보들이 한눈에 보기 쉽게 정리되어 있어서 좋았습니다.
시인성도 좋아서 다이빙 중 도움이 많이 될 것 같다는 느낌을 받았어요.

로그 기록 기능도 만족스러웠습니다. 다이빙 후 기록을 남기고 다시 확인하는 과정이 편리하고 정리가 깔끔하게 되어 있어서 로그북 관리하기 좋았습니다.

전체적으로 실제 다이버 입장에서 필요한 기능들이 잘 담겨 있다는 느낌이 들었고, 디테일도 신경 써서 만든 앱이라는 인상을 받았습니다.

다이빙 컴퓨터로는 최고에요!

오셔닉만 사용하다가 이거 처음 써보는데
가격도 저렴하고 워치에서 다이빙 인터페이스를 바꿀수있는게 신기합니다..!

인터페이스 변경이 조금 더 자유로우면 더 좋을거같아요
