v2.2.2 Update · Added support for iPhone Duo · Changed how the surface interval and no-fly time are displayed · Various fixes and improvements

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

v2.2 Update New · Export & Import: export your dives as CSV, UDDF or JSON and import UDDF files. Imported dives are never used for no-fly time, NDL, decompression or CNS · CNS% and OTU tracking on the watch (shown on the Technical gas page), with an early warning at CNS 80% and an alert at 100%, saved with your logs · Trips suggested from your dives, saved only when you accept them · Diver Card with your certification and card photos. A shared card image leaves out your certification number by default · Dives recorded from now on show their time in the dive site's local time; older logs are marked as estimated · No-Fly Minimum Wait and Surface Interval widgets on iPhone and complications on Apple Watch · Freediving: optional depth, dive time and rest alerts (off by default) and a Dive Analysis on iPhone Design · iPhone: a new look with the system tab bar, and a depth chart with its own water temperature strip · Apple Watch: a redesigned Minimal screen that keeps your MAX ring, a pre-dive checklist in Ready Mode, and a choice of Technical bottom bar items, including heading (HDG) Apple Watch · Scuba is now offered only on Apple Watch Ultra; other models keep the freediving modes they support · If the workout briefly fails to start, the watch now retries automatically instead of showing the "workout failed" alert. If the workout recovers after that alert, you see "Dive session restored" · Alarm texts point you to your stops, a shallower depth or your backup computer instead of just saying "ascend" Subscription · All features stay free through the end of 2026. After that, your logbook, existing reports, export and import, iCloud backup, planner, Diver Card, trips and no-fly status stay free. Pro covers new AI reports, new Studio projects and starting a new dive on the watch before Water Lock is on. If the watch is already in the water with Water Lock on, the dive screen still opens without Pro Fixes · Profile and emergency information edits are kept when you go back, the 3D route no longer blocks scrolling, and an earlier dive's log shows the minimum wait still running

v2.1.2 Update Apple Watch · Releasing Water Lock by pressing and holding the Digital Crown now stays released. At the surface, releasing Water Lock now properly ends Ready mode and the dive (underwater it locks again, as before) · Fixed a "Workout failed to start" alert that could appear when opening the dive screen after the app had quit unexpectedly

v2.1.1 Update Water Lock · Water Lock is released by pressing and holding the Digital Crown until "Unlocked" appears. Our instructions said to turn the Crown, which does not unlock on current watchOS — corrected on the watch, in the freediving controls and in the iPhone guide Apple Watch · Releasing Water Lock at the surface ends Ready mode again · A dive started at the surface without entering the water now ends when you release Water Lock. It keeps running while you are deeper than 1.2 m (4 ft) or while a decompression stop is owed · In scuba mode, if the watch app opens while you are already in the water, it now arms Ready, so even a slow descent starts the dive · Dives that never reach 1.2 m (4 ft) are not saved, and the end summary now says "Not saved"

v2.1 Update The iPhone app is now four tabs · Today · Logs · Plan · Me — the screens you use most are at the front · Today gathers your last dive, average heart rate, score trend, the map of your dive sites, average water temperature and average SAC on one screen · In a dive log, the AI analysis now sits directly under the profile chart · A log with anything unmeasured tells you what is missing — route, entry GPS, water temperature, GF — and why Records no longer disappear · Generating a report for an older dive could delete another dive's measured report, on the device and in iCloud · Sync could report itself complete when backup was off or iCloud was unavailable · A manually entered end pressure was not learned into your personal SAC baseline Apple Watch · When the app comes up in the water it opens the dive instrument, not the card menu — there is no longer a screen you cannot leave under Water Lock · Ascent rate no longer stays red at an old value after you stop at the surface, and three-digit values are no longer cut off · If a safety stop is interrupted, the instrument tells you what is left · Freediving: a dip that did not count no longer disturbs the rest timer or the previous profile, and the guidance for ending a session under Water Lock is correct · Metre values that were typed into text now follow your unit setting — the instructions no longer read wrong in feet Display, translation and accessibility · Fixed text that was cut off in all 14 languages — instrument labels, logbook rows, the three-column summary, banners and toasts · Counts now follow each language's singular and plural rules · Lists and summaries were relaid out so they no longer collide at large text sizes · Dive times could print a single-digit minute Also · Report: a dive with no heart rate reading showed "−100%", list order by date, risk chart guidance · Planner: the depth scale shifted when you changed units, and the MOD note now matches the actual limit · The grade symbol beside the score is gone. The grade is still shown as text and as the score itself

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.

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
