Slopes is optimized for the iPhone Duo! Use a compact interface with a smaller map when the Duo is folded, or open the Duo to take advantage of much larger full-screen maps.

- Quick fix for a crasher where bad recordings that had been silently failing to upload in the past were now crashing the sync engine.

Previous release notes for our iOS 27 release:

- Huge improvements to the recording engine moving Slopes beyond just lifts & runs at resorts:
- When you start in uphill/skinning mode, Slopes now shows live ascent stats.
- A new dedicated cat ski mode for the backcountry that's tuned specifically for identifying cat rides vs skiing.
- In regular downhill ski mode, hiking is detected separately from lifts. Hikes show live ascent stats, and post-recording totals them separate from lifts.
- Better suppression of "phantom runs" during small uphill segments of runs. We'd merge them back into the main run in the end, but your run count could look inflated mid-run if you checked your stats.
- Improved our "trim the fat" logic we apply to the start/end of runs to better cut out lift-lines & time waiting for friends at the top of the lift.
- Slopes now works in landscape on iPhone, with a wider layout that makes the most of the extra room.
- The Overview / Analyze / Vitals switcher is back on the playback card instead of only being accessible under the "..." menu.
- You can now pinch to zoom into live photos.
- Slopes will now use the heart rate zone ranges in Apple Health when available (iOS 27+).
- Fixed a case where drive-away detection could fire if you were bombing a run mid-day.
- Fixed searching for seasons, where '2025' only matched '2025/25' and not '2024/25'.
- Fixed several peak altitude issues: the value in your season summary now matches the activity and the 3D scene shows the right peak.
- Fixed "solo days" counting individual solo recordings instead of actual solo days, and a streak day-count that could be off by one for skiers outside GMT.
- Fixed snow conditions where "dumping" and "fresh powder" could get swapped.
- Offline map fixes: updating a digital map no longer forces a full re-download, "Erase all" now fully clears your paper maps, and we resolved a couple of related crashes.
- Fixed an upcoming trip itinerary that could stay stale after you edited it.
- Fixed Logbook lifetime stats not counting up on first appearance, and missing run-number indicators during playback on iOS 17/18.
- Fixed some cases where the map could get stuck in a loading state, never showing activity data.
- Fixed a case where trip attendees could appear duplicated.
- Squashed several crashes.

Going forward Slopes now requires iOS 18 or watchOS 11.

Going forward Slopes now requires iOS 18 or watchOS 11 (Watch Series 4 is the only hardware dropped as a result of this).

- Lots of UX improvements for the timeline editor:
- Added a movement heat-bar to help you set the start/end of lifts/runs and avoid including time in lift lines.
- Added labels ("Run #1") and duration to the lift/run blocks.
- Live-updating of the lift/run's GPS path on the map while you drag the start or end to a new time.
- Higher contrast for the full day's GPS path and the action you're editing.
- Switched to Slopes's custom resort maps so it is easier to snap to lifts.
- UI tweaks to modernize the screen and bring it more inline with iOS 26.
- Slopes will no longer re-open to a recording or resort you looked at days ago. Instead we now only restore the last thing you were doing if it was within the past 10 hours or so.
- Improved GPS recovery logic for rescuing briefly-lost location points.
- Fixed multiple crashes on launch, including one that was sending some iOS 26 users into a crash loop.
- Fixed a couple of crashes that could happen during or at the end of a recording session.
- Fixed a crash for Ask to Buy users: if a parent approved an in-app purchase while you were waiting, the app could crash.
- Fixed several crashes that could happen seemingly at random — loading resort details, network activity, and smart recording reminders.
- Fixed crashes in the daily AR playback scene on iOS 26, usually related to opening and closing it multiple times.
