Strata – An app that talks me out of dying outdoors

# Strata — know your pitch before you commit to the line Source: [https://strata.highloop.co/](https://strata.highloop.co/) Backcountry trip planning · iOS No spreadsheets, no five\-app shuffle\.

Plan it, track it, and bring your crew home\. Native iOS, offline maps, no ads\.

It makes the call\. Other apps hand you a slope\-angle layer and a weather widget and leave the judgment to you at the trailhead\. Strata weighs the things that actually hurt people — wind slabs on lee aspects, steep rollovers, a forecast turning while you're above treeline — and gives you one verdict you can read in five seconds\. ⛷ Tamarack Peak · N–NE aspect · today Watchverdict · wind slab forming Consid\.Avalanche danger · 9,500 ft and up 34°max slope on the standard line SE <32°Strata's safer alternative ## Works solo\.

Track recording and your planned route keep working long after the bars disappear\. ## Pro: draw lines that snap to the mountain The Pro route builder snaps every waypoint to real trail geometry using a precomputed graph and A\* pathfinding, then vets the line against slope angle, aspect, and today's avalanche danger\.
