Easier to get around • A back arrow now reappears whenever you scroll up, so you're never stranded partway down a long page. • The Privacy Policy and Terms of Service now open inside the app and follow your chosen display theme, including Tactical Red for night vision. New tools and reference content • UV exposure estimator with burn-time guidance. • Storm turnaround timer for alpine days. • Snow blindness and lightning safety entries. • Wildlife list reorders to the region you're in. • Copy or share your GPS position for a rescue call or satellite messenger. • Swipe from the left edge to go back. Reliability • More dependable SOS flashlight beacon and clearer GPS accuracy reporting. ### 1.6.2 — 2026-06-01 This update hardens the app for backcountry use: • SOS strobe now uses your iPhone's camera flash (torch) on multi-lens models, so the distress signal is far brighter than screen flash alone. • "Return to Camp" GPS now shows how accurate each saved waypoint is (±meters) and warns you when a fix is weak — so you can re-mark before you rely on it. • New Lightning Safety guide (NWS/NOLS based): when to seek shelter, the "if you hear thunder" rule, strike avoidance, the 30-minute wait, and strike first aid. • Reference diagrams (knots and more) now show a clear "unavailable offline" notice with a Retry button instead of a blank space. • Added native haptic feedback — the breathing exercise now buzzes — for eyes-free use. Note: this version now requires iOS 16 or later. ### 1.6.1 — 2026-04-09 Accessibility & quality improvements: • Focus trap on check-in dialogs: keyboard and assistive technology users can now navigate Check-In cognitive tests and emergency overlays without focus escaping • Tactical Red night-vision theme: fixed invisible text on toast notifications (warning, info, success messages now readable) • Pedometer: screen reader announces step count and distance when tracking stops • Fixed a timer cleanup issue in the Check-In cognitive test ### 1.5.5 — 2026-04-05 • Waypoint Photos — Attach a photo to any saved GPS waypoint for visual confirmation when you return. Perfect for camp, water sources, and trail junctions where terrain looks uniform. Photos auto-resize and stay on-device (no cloud). • Camera Heart Rate — Fixed finger placement instructions with an iPhone-specific diagram. The measurement now correctly tells you to press your fingertip diagonally across the Main 1× lens AND the Flash (they're at opposite corners of the camera plateau). Much more reliable pulse readings. • Safety Banner — Swipe left to dismiss the safety notice at the top of pages. Visible hint added so the gesture is discoverable. • Under the hood — 22 new tests, atomic photo storage with LRU eviction, orphan cleanup on app launch. • Waypoint Photos — Attach a photo to any saved GPS waypoint for visual confirmation when you return.

Slope Inclinometer — Measure slope angle in real-time using your device's motion sensor. Color-coded avalanche risk zones (low, moderate, high, extreme).
