Know before you drive. ClimbShade shows whether your climbing area will be in sun or shade, whether the rock will be good, and whether wildfire smoke will spoil the day. Built for sending season: crisp mornings, cold shade, warm sun walls and smoky afternoons. Pick the right wall at the right time. SUN & SHADE MAP Real terrain shadow simulation on an interactive map. Scrub through the day and watch shade move across the wall. Chase shade in summer heat or sun on cold winter mornings. SEND CONDITIONS Temperature, humidity, wind and recent rain, combined with your rock type's friction profile, become a simple green / amber / red score. Granite on a crisp morning? Green. Sandstone after rain? Red. AIR QUALITY Hourly Air Quality Index during daylight, color-coded by EPA category. Your climbing recommendation accounts for smoke, so you'll know when to stay home. 7-DAY CLIMBING FORECAST Hourly temperature, humidity, wind, precipitation and AQI in a glanceable chart made for climbers. THOUSANDS OF AREAS & ROUTES Search areas and routes from OpenBeta, the open-source climbing database. Filter by grade for boulder, sport and trad, with V-Scale, YDS and French grades. APPROACH NAVIGATION Trail-following approach routes from the right trailhead and parking, with elevation-aware time estimates. WORKS OFFLINE Download areas by state. Saved areas, routes, maps and approaches work without signal. Less guessing, more time on rock. ## Is ClimbShade safe? Not enough ratings yet to assess ClimbShade. ## Is ClimbShade legit?

FORECAST & CONDITIONS • New hourly table with temperature, feels like, rain, gusts, humidity and air quality • Redesigned 7-day forecast: tap a day to see its hours • Air quality (AQI) added to recommendations • Gust-based wind warnings and a new "muggy" caution • Set your own heat limit from the recommendation card • Fixes for the "Best conditions" time and the forecast staying on yesterday after midnight OFFLINE SAVED AREAS • Saved areas work fully offline, including approach and shade • A status icon shows when each area is ready offline • Find Shade works offline for saved areas MAPS & SEARCH • Directions from area details now work on iPhone and iPad • Blue "my location" dot and familiar directions icons • Search shows distances, ranks exact matches first, and adds "Search here" • Same-named areas in different regions now all appear ### 1.2.9 — 2026-10-03 NEW: AIR QUALITY Wildfire smoke can turn a perfect send day into a bad one. ClimbShade now checks the air for you. • The Forecast tab shows the daytime peak Air Quality Index (AQI), color-coded by EPA category • Pick any hour to see its AQI next to temperature, rain, wind and humidity • Your climbing recommendation now accounts for air quality. At AQI 101–150 it says "Proceed with Caution", with advice for climbers with asthma or heart or lung conditions. Above 150 it says "Not Recommended", because hard climbing means heavy breathing for everyone • Only sunrise-to-sunset hours count, so an overnight smoke spike won't write off your whole day SHADE IMPROVEMENTS • Fixed cliffs wrongly switching from sun to shade when zooming in • Find Shade now shows shade times for many more routes, including routes outside the US that used to show none • Fixed unshaded gaps along the edges of the shade overlay ### 1.2.8 — 2026-08-03 We rebuilt ClimbShade's shade engine from scratch — replacing a third-party SDK with a custom shadow engine that's faster, more accurate, and works reliably on iOS. Also included: sharper shade at popular crags, a new time scrubber to watch shade move through the day, more reliable maps, and a fix for Navigate occasionally showing the wrong approach distance/time. ### 1.2.3 — 2026-07-15 This update focuses on more reliable navigation and offline support: • Approach routes now pick the correct trailhead and parking location far more reliably, and follow real trail paths with elevation-aware time estimates instead of straight-line guesses. • Offline downloads are more robust — route counts, map pins, and elevation data now stay accurate when you're out of signal. • Area and route search is faster and no longer returns duplicate or mismatched results. • Refreshed app icon and splash screen. • Numerous stability and navigation fixes throughout the app. ### 1.2.1 — 2026-06-18 Grade Filters Find your next climb faster. The route list now has per-style grade filters with chips that match the grade system for each style. Dial in your range and see only the routes that fit. Faster, Smarter Search Search results for both areas and routes come back faster and more relevant. Nearby areas load from your GPS location directly. Offline Support ClimbShade works better without a signal now: - Saved areas and their routes are instantly searchable offline - Approach routes cache after your first visit — Navigate works even when you lose signal on the drive in - The navigation map loads without a connection - Downloads by state are now available — no areas go missing Navigate Tab Switching between areas no longer reloads the map. Approach distances and trailhead detection are more accurate, and the selected area pin stays visible after you dismiss the area detail sheet. Bug Fixes - Fixed GPS location not updating - Fixed routes appearing empty on first load - Fixed search results not opening the area detail - Stability improvements throughout ## Apps similar to ClimbShade | App | Rating | Price | Category | | --- | --- | --- | --- | | [Shadō: Climbing Conditions](https://appshunter.io/ios/app/shado-climbing-conditions/id6748621552) | 5.0 (5) | Free | Sports | | [Nivocheck 1.0](https://appshunter.io/ios/app/nivocheck-10/id6443719048) | 2.0 (1) | Free | Sports | | [Atlans](https://appshunter.io/ios/app/atlans/id6714484925) | — | Free | Sports | | [Boulder Trainer: Hangboard](https://appshunter.io/ios/app/boulder-trainer-hangboard/id770657161) | 4.6 (860) | Free | Sports | | [Gora - Find climbing partners](https://appshunter.io/ios/app/gora-find-climbing-partners/id6761748578) | 4.8 (4) | Free | Sports | | [hang! - hangboard timer](https://appshunter.io/ios/app/hang-hangboard-timer/id6476608721) | 5.0 (30) | Free | Sports | ## More apps by SummitFlow, LLC - [Topo360](https://appshunter.io/ios/app/topo360/id6754182552) - [onBelay Partner Finder](https://appshunter.io/ios/app/onbelay-partner-finder/id6760911332) All apps by SummitFlow, LLC: https://appshunter.io/developer/1846962764 ## Related topics [climbing weather](https://appshunter.io/ios/topics/climbing-weather) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
