Scenic Map vs Avyline

A 3D topo map with coverage of the entire world. The map is streamed directly from Apple's servers and cached on your device for use when there is no cell coverage. Use Scenic Map in a car, a boat, a plane or while hiking. It is like having the entire Earth in your pocket. Satellite image overlays add breathtaking detail and realism to the maps (tap preset 2 or 4). You can use them as you travel to see what is hidden from view at ground level. This takes moving maps to a whole new level. To get started, tap the arrow button in the toolbar to begin GPS tracking and center the map at your current location. The spinner in the status bar shows that the map is being loaded. The spinner stops when the map is fully cached at that location. You can scroll around the map or tilt the map with a two finger vertical swipe to see it in 3D. Use the two finger vertical swipe gesture to tilt the map for a 3D view. Scroll like a map or fly like a flight simulator. Enable Joystick Gestures in the Settings menu and then fly around the terrain using a virtual joystick. Prefer only 2D maps? Enable the 2D Map option in the Settings menu. Scenic Map is simply the best 3D topo map available for a mobile device. You will see incredible detail while scrolling, rotating and zooming perfectly smoothly. You will see every road even if you zoom out to the altitude of a satellite. As you zoom in, you will see every small bump and hollow of the Earth and terrain features as small as ten meters. Unlike old fashioned topo maps, Scenic Map’s roads and trails are up to date thanks to OpenStreetMap.org. It contains polygons for urban areas, shopping malls, an ever growing number of buildings and many other features, The best lake, pond, stream and rivers from the USGS and Canadian public databases are also included. Your tracks can be replayed with video like controls to speed up, slow down, pause, restart or skip to the end. You can display existing tracks while recording another if you want to retrace your route. When online, you can automatically create a route from your current GPS location to any other point on the map. Tracks can be received from or sent to other apps in GPX format. GPS recording stops automatically after you have remained stationary for some time or you can choose to manually stop tracking by tapping on the top track in the Tracks view. Never before have maps been this customizable. For example, you can turn on or off the roads. You can change the lighting direction or remove terrain shading entirely. You can display contour lines even over satellite images. There are five presets which let you quickly switch between map styles. Use Metric, English or Nautical units and choose one of four different coordinate displays including UTM. Want to learn more about a map feature? Tap the target icon and center the feature under the compass rose to display its name, type, urban area, county, state, elevation and coordinates. You will also see a bearing line back to your current GPS location or from your location to a selected waypoint. The status bar shows the bearing direction and distance along with the map and GPS elevation, the track length, and your current speed and direction of travel. In-app documentation is provided in the Help section at the top of the Settings menu. Links are provided in the documentation to detailed coverage maps, tutorial videos, installation guide and blog at ScenicMap.com Map data © OpenStreetMap and contributors under the Open Database License Scenic Map supports GPS tracking while the app is in the background. Caution: Continued use of GPS running in the background can dramatically decrease battery life.

Avyline is an offline 3D terrain planner for backcountry skiing. Draw your line, see how steep it gets and where the steep ground lies, compare alternatives and export the plan — all with zero cell signal. Estimated slope, steep ground ahead and the official forecast, on one map. PLAN YOUR TOUR • Draw a route and read its elevation profile, the share of its length on ground ≥30° (from elevation data) and estimated time (a range, never a single number). • Corridor analysis breaks the line down: continuous steep sections, overhead steep terrain, potential terrain-trap indicators, aspect rose and elevation-band distribution — terrain facts only, never a safe/unsafe verdict. • Compare two routes side by side on the same facts. Add backup routes, typed waypoints (observe / decide / turn around) and No-Go zones. • Simulate sun and shade by date (free). Export the plan as a PDF or image card with map attribution and a timestamp footer (Pro). • Reuse a plan as a template for a new date (forecast and sun reload). Import routes from other tools — GPX free, plus KML, KMZ and FIT with Pro. • Browse curated classic lines and community ski tours and load one into the planner (free where regions have them). FREE TERRAIN BASE, ALWAYS ON • Slope readout estimates the slope around your position from offline elevation data; turn alerts on (off by default) for a one-time warning when you enter terrain steeper than your threshold. • Look-ahead check samples the corridor ahead and flags steep ground before you reach it — it does not detect avalanches, obstacles or snow. • Steep-ground shading colours terrain at or above 30°; when an official forecast exists, its regional band rating only sets the shade strength — an area input, not a per-slope verdict. • Slope alerts, look-ahead check, steep-ground shading, the slope map, terrain exposure and official forecasts are free forever — never paywalled. OFFICIAL FORECASTS, SHOWN HONESTLY • Avalanche danger ratings from official public warning services (avalanche.org member centers, SLF and EAWS partners), broken out by elevation band — in the regions those services cover. • Ratings expire automatically at their validity end. "No rating" is its own state — never shown as "low danger." • Every forecast shows its source and publication time. TRUE OFFLINE 3D • Each region (~5–40 MB, sized to area and resolution) packs high-resolution terrain, aerial/satellite imagery, contours, hillshade and place names — downloaded once, then usable with no signal at all. • Slope, aspect, contours and shaded relief rendered at 60 fps by an in-house engine. • The Terrain Exposure layer classifies avalanche terrain into three in-house grades (1–3), computed on-device and honestly labelled as not an official rating. • Search peaks, passes and huts; save your own waypoints. FREE VS PRO • Free: one downloaded region, the entire safety base above, every map layer, sun & shade simulation, curated classic lines in the planner, and a taste of planning — draw one route with its profile. Safety is never paywalled. • Pro (a single annual subscription, $4.99/year): the full planning toolkit — corridor analysis, A/B route comparison, backup routes with typed waypoints and No-Go zones, plan-card export (PDF/image), templates, KML/KMZ/FIT import, unlimited saved plans and every supported region, fully offline. IMPORTANT Avyline is a decision-support tool, not a substitute for formal avalanche training, a current official forecast, beacon/shovel/probe or your own judgment. Corridor analysis and profiles report terrain facts only — they never assess snow stability or issue a safe/unsafe verdict. Terrain angles come from digital elevation data with finite accuracy, which the app discloses openly. A low ≥30° share is not low risk: overhead slopes and runout zones can lie outside the corridor. Travel in avalanche terrain at your own risk. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
