You Need A Map vs Avyline

If you get lost or in an emergency, YOU NEED A MAP! A map that covers the entire USA, all 50 states. A map that works everywhere even without a cell phone signal. A map that shows not just roads but also terrain, streams, lakes and other landmarks. Note: If you would prefer a small app that caches online maps covering the entire world, please see the More by GrangerFX section below and try the free Scenic Map app. Get You Need A Map if you want an offline map the entire USA as a single large download. The paid apps have built in maps with full resolution terrain. Your iPhone has a great online map but all it takes is one wrong turn and you could find yourself lost with no cell phone signal. What is the fastest way back to the highway? Should you go forwards or back? Is there a better road just a short distance away? Is there a raging stream or an steep cliff between you and the road? YOU NEED A MAP! You Need A Map is a huge application. It has to be. It contains every mountain, hill, stream, lake, pond, freeway, highway, local road and track. In addition it contains many buildings, trails, railways, points of interest and polygon features. It has everything you need to find out where you are and what is around you anywhere in the USA. Most navigation apps on the iPhone and iPad must transfer all their maps from servers on the internet. This can be slow in areas with only 2G coverage or completely unavailable in wilderness areas where a map would be most useful. You Need A Map solves this problem by storing maps directly on your iPhone or iPad. This extremely fast high quality software renderer is the first of its kind for mobile devices. If you do have a cellular or WiFi internet connect, Satellite image overlays add breathtaking detail and realism to the maps (tap preset 2 or 4 when Online Map is enabled). 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. Tap the arrow in the toolbar to enable GPS tracking. As you move, you will generate a track file which you can replay. You can also import GPX tracks generated in other programs and play them. While recording or playing a track, the map will be centered on the current location and rotated towards the direction of travel and rendered in 2D or 3D with silky smooth animation. When playing a track, you can speed up, slow down, pause, restart or skip to the end. Send your GPX tracks to other apps or email them. Want to learn more about a map feature? Click the target icon and center it under the compass rose to display its name, feature type, urban area, 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 will display the direction and distance along with the map and GPS elevation, the track length, and your current speed and direction of travel You Need A Map uses the same code as Scenic Map and has most of the same features. These include many map customization options, customizable waypoints, direction and bearing information, a smooth scrolling moving map display while driving or flying, city search and much more. You can also get the full feature set of Scenic Map with an in-app purchase including the new online maps of the entire world. Documentation, detailed coverage maps, installation guide and blog are available on ScenicMap.com You Need A Map covers the entire USA including all 50 states Map data © OpenStreetMap and contributors under the Open Database License You Need A 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/
