A NEW INTERFACE Speed Vario 3.0 opens on a question: what are you doing today? Walking, cycling, driving, skiing, paragliding, flying or on the water - each tile says what the mode does, and the screen that follows belongs to it: its colours, its figures, its cards. Before you start, altitude and heading; during the outing, what matters for that activity - pace and cadence on foot, runs on skis, QNH and airtime in the air. Start, Pause and Stop stay under your thumb wherever the screen is scrolled. LIGHT OR DARK The app now follows the iPhone's appearance, or the one you pick in Settings. Light is drawn for full sun; dark remains the instrument you know. THE LOGBOOK History becomes a logbook: by activity and by period, with the totals up top - outings, distance, flight hours, runs - and the outings grouped by month. A flight opens on its log. SETTINGS Four groups instead of one long list. Whatever depends on an activity - units, vario, pressurised cabin, max HR - is set from its dashboard, behind the activity chip. iCLOUD BACKUP Your outings can now be copied to your own private iCloud space as they are recorded, and synced between your devices. Optional, offered at launch, switchable at any time in Settings. No account to create and no developer server: the storage is yours. Heart rate and active energy never go to iCloud - they stay on the device and in Apple Health, where the app reads them back after a restore. Plus a guided tour rewritten for the new layout, a watch label that no longer gets cut, and an iPad that shows the list beside the outing. Nothing leaves the device unless you ask it to: iCloud backup is optional, and off by default.

ALTITUDE COULD FREEZE The displayed altitude could lock onto a wrong value and stay there for the rest of an outing - 656 m shown on a 1250 m summit. All it took was iOS repeating one cached position for half a minute while you climbed. The GPS reference settled onto it, then refused every fix that came after - including the good ones, and the more correct a fix was, the more surely it was refused. The recorded track and the elevation gain went with it. Between fixes, that reference now follows the barometer: it can no longer fall behind a climb. CABLE CARS AND LIFTS The same fault from another angle. Inside a cabin the altitude could jump by several hundred metres, or slide back down towards the valley station while you rode up. The vertical speed stayed correct from beginning to end - which is what made the symptom so hard to read. Fixed by the same change. Both affected every mode except aviation, whose altitude is computed separately.

FLIGHT LOG An aviation flight now lists every time the aircraft met the ground: takeoffs, landings and touch-and-goes, each with its Zulu time, the airfield, the runway used and the speeds. A touch-and-go gives the three that matter - arrival over the threshold, slowest point of the roll, liftoff - named rather than run together. All of it is worked out on the device from a bundled airfield and runway database: no network, no account. GUIDED TOUR On first launch, a tour in three parts shows where everything is, with an arrow on each real control: the live screen, your history and its four views, the settings worth knowing, and the Apple Watch. Replay it any time from the ? button at the top of the screen. AUTOMATIC LANGUAGE A new Auto setting, on by default: the app follows the iPhone's language, regional variants included, and falls back to English when that language isn't one it offers. An explicit choice is still kept. SPEED AND PACE ON THE WRIST The watch now combines the Doppler's reactivity with the level of the distance actually covered. Walking, the Doppler alone under-read speed by about 16%; pace and displayed speed now agree with the distance. STEADIER WATCH RECORDING When watchOS ended the workout session mid-recording, background GPS stopped without a word and the track was cut the moment you dropped your wrist. The app now restarts the session, and tells you if it cannot. SIMPLER SHARING One button inside a track: the 3D video and the five file formats sit at the top level instead of two menus down. FIXES • 3D terrain: the satellite ground was not drawn at all. • Aviation: landing speeds could be badly wrong - 25 knots reported where the aircraft had touched down at 60. The touchdown is now timed on pressure altitude, which the GPS vertical error does not reach. • Video export could run out of memory on a long track; the terrain caches are now bounded. • The demo track shipped with the app vanished on first launch, deleted by the retention period. • VoiceOver announces the replay scrubber, the heart-rate zones and the share button.

VFR STOPS An aviation flight now lists the aerodromes you actually landed at along the way, not just where you took off and where you finished. A landing only becomes a stop once the aircraft has stayed on the ground a couple of minutes, so circuits and touch-and-goes never turn into a string of false entries. The session list shows the chain at a glance; the flight summary gives every field with both its codes. SHARPER TRACKS The map and the 3-D views now spend their detail where the trajectory actually bends. A straight cruise leg used to cost as many points as a turn, which left a two-hour flight with one point every 12 seconds — about 670 m at 200 km/h, so a turn came out as an angle rather than a curve. Turns now keep their shape, and long straights cost almost nothing. WATER MODE Nautical mode is now simply called Water: it fits swimming, rafting and kayaking as well as it fits a boat. On Apple Watch Ultra it now measures what it always promised — water temperature, depth, and how long your wrist stayed under. A dedicated screen appears on its own the moment you go in, which matters because the touchscreen locks underwater, and hands your previous page back a few seconds after you surface. DEPTH, RECORDED Every reading the depth sensor takes is now kept with the track, on the sensor's own clock instead of only when a GPS point happens to land. The whole immersion profile is there as a chart in your history. ON THE WATCH FACE The complication now shows the activity and the running session timer, instead of just an icon to tap. EASIER TO READ • Charts in session details can be played as sound with VoiceOver • Settings, history and several watch screens follow your text-size setting • In Always-On, chronometers drop the seconds rather than show a figure the dimmed screen cannot keep up to date • In Water mode the watch puts D+ and D− on one line, which frees a line for altitude FIXES • A watch recording could come out with its entire altitude track offset by tens or hundreds of metres. The barometer silently re-zeroes itself mid-session; the import now follows that instead of carrying the jump through the whole track. • A CSV exported with vertical speed in m/h read back sixty times too fast. • Water mode remembers the units you pick for it, without disturbing the ones you use elsewhere.

APPLE WATCH COMPANION APP SpeedTracker now includes a full Apple Watch app. Three pages accessible with the Digital Crown: • Page 1: Speed, distance, altitude and vertical speed (Vz color-coded green/red) • Page 2: Elevation gain/loss, duration, heading and GPS quality • Page 3: Activity mode, GPS coordinates, pressure, QNH (aviation) or MSLP (nautical), and session controls Start, pause, resume and stop sessions directly from your wrist. Available in English, French, Spanish, Arabic and Chinese. GPS FILTERING Each activity profile now uses its own optimised signal processing parameters. Vertical speed response tuned per activity: more reactive for paragliding, smoother for aviation, revised for ski. Nautical mode uses a less aggressive noise gate on calm water. BACKGROUND GPS During an active session, GPS runs uninterrupted. Outside a session, GPS stops automatically after 10 minutes in background. The manual Auto-Stop setting has been removed. LIVE SCREEN The activity profile selector is now integrated into the session card. Charts redesigned: three stacked charts replaced by a single swipeable chart (Speed / Altitude / Vz). SESSION HISTORY New cumulative D+ chart mode. Stats row visible below the chart in all view modes. LIVE MAP Zoom level adapts automatically to the activity (walking ~200 m, aviation ~15 km). Playback speed selector (1× / 5× / 15×) always visible. End-of-track marker shown while scrubbing. BUG FIXES • 3D Terrain: relief was displayed mirrored north-south when using a Mapbox token. Fixed. • Live D+/D−: elevation gain was underestimated on gentle slopes. Fixed.

3D TERRAIN VIEW - Resolution picker (512 / 1024 / 2048 px) directly in the view, no more digging into Settings. - Progressive loading: terrain appears instantly and sharpens in three passes. Camera position preserved. - Vertical multiplier (1x / 2x / 3x / 5x) to adjust relief exaggeration on the fly. - Faster and more reliable elevation fetching. SESSION DETAIL - Map overlay now has a single switchable chart - tap spd / alt / vz to toggle. Stats row and scrubber stay fixed while scrolling. LIVE SPEED - GPS signal quality indicator with 5 levels (no fix to excellent). - "GPS speed unreliable" warning when no valid speed source for more than 2.5 s; display fades to zero after 5 s. - Position-based speed fallback when Doppler is unavailable but position accuracy is 20 m or better. - IMU-adaptive smoothing: the accelerometer reduces filter lag during hard braking or acceleration. - QNH display in Aviation mode. ALTITUDE & ELEVATION - Barometric anchor only recalibrated from GPS when vertical accuracy is better than 15 m - urban canyon fixes no longer corrupt altitude. - D+/D- accumulation gated on a noise floor to eliminate barometric drift inflation. - Foreground resume fix: no altitude jumps or vario spikes after returning from background. OTHER - Measurement engine refactored: transport mode now drives outlier rejection thresholds for both speed and vertical speed. - Demo track pre-loaded on first launch. - Map mode selector moved next to the back arrow. - Chinese and Arabic translations added.

3D Terrain Resolution — new setting to choose between Low, Medium, and High texture quality Terrain loading is now more reliable with automatic retries on network errors Hint shown during terrain loading when no Mapbox token is configured Minor localization fixes (EN / FR / ES)
