Guru Maps vs AviNavi

Explore the world offline with Guru Maps — detailed maps, turn-by-turn navigation, and GPS track recording that keep working when you have no signal. Download maps once and use them anywhere (powered by OpenStreetMap). Plan routes, record adventures, save favorite places, and sync everything across devices. OFFLINE MAPS • Download maps for countries or regions and use them fully offline. • Rich detail and millions of places. Monthly map updates. NAVIGATION THAT WORKS OFFLINE • Voice-guided, turn-by-turn directions with automatic rerouting. • Lane guidance for clearer driving in complex junctions. • Modes: car, bike, truck, walk, plus straight-line navigation (great for sailing or off-road). ROUTE PLANNING • Build multi-stop routes with custom waypoints. • Choose fastest or shortest route and save your plans. • Export routes to GPX/KML to share or back up. TRUE 3D RELIEF & TERRAIN • Preview hills and valleys in True 3D Relief. • High-detail terrain: contour lines, hillshade, and topographic overlays. • Elevation profiles and slope charts for smarter planning. GPS TRACK RECORDING • Record tracks with one tap (even in the background). • Live stats: speed, distance, time, altitude. • Analyze tracks with interactive graphs and export to GPX/KML. FAST OFFLINE SEARCH • Search by name, address, category, or coordinates — offline. • Instant results as you type, with multi-language support. POI & ORGANIZATION • Save places with custom pins and icons. • Organize everything into folders and share with friends. OPENING HOURS • See opening hours for places when available.

AviNavi is a VFR pilot's companion built around a single live map. Four tabs — Radar, Plan, Fly, Setup — share one view so context never resets between phases of flight. RADAR • Live ADS-B traffic with aircraft icons, callsigns, altitude and ground speed. • Tap any aircraft for a detail panel with route, photo, telemetry and recent flight history. • Airspace polygons with altitude limits, centroid and boundary labels, AUP activations under each airspace. • ATZ polygons turn red when their aerodrome has an active NOTAM — at-a-glance heads-up for current restrictions. • Airport runways drawn to scale, with METAR, frequencies and NOTAMs in the side panel. • Optional GDL90 broadcast feeds the live ADS-B picture to SkyDemon, ForeFlight and other compatible apps over Wi-Fi. PLAN • Tap to add waypoints; they snap to nearby airports, navaids or obstacles. • Long-press to drag waypoints or split a leg. • Cruise speed, altitude and fuel consumption from your active aircraft profile drive ETA and fuel-required-at-each-waypoint. • Save and load flight plans — synced across your devices via iCloud. FLY • Cockpit HUD: ALT (MSL), AGL with terrain lookup, ground speed, vertical rate, QNH from nearest METAR (within 150 NM). • Heading rose, own-ship track vector with 2/5/10-min ticks, coloured by the airspace each segment passes through. • Vertical proximity warning shades the top edge of the screen when you're approaching the floor of an airspace above. • Nearby-airspace alert engine with proximity distance to polygon edges (not just vertices). • Active flight-plan overlay with live distance and ETA to the next waypoint. • GPX track recording with start / pause / save controls; files saved to Files and iCloud Drive. • Display never dims while on this tab. WEATHER & NOTAMs • METAR, TAF and SIGMET from aviationweather.gov. • NOTAMs through Autorouter (EUROCONTROL EAD) with FIR-level fallback so warnings filed under the FIR but mentioning your aerodrome still surface. • Daily Czech AUP integration for temporary TRA/TSA activations. AIRCRAFT PROFILES • Multiple profiles with callsign, ICAO24 hex, type, cruise speed, cruise altitude and fuel consumption. • ICAO24 hex filters your own ship out of the ADS-B feed and identifies you on the GDL90 broadcast. • Profiles, saved plans and API tokens all sync via iCloud and iCloud Keychain. OFFLINE • Cached airspaces, airports, obstacles and terrain elevation continue to work without a connection. • Network errors are silenced when offline; a single banner tells you the state. AviNavi is intended as situational awareness for VFR flight. It is not a substitute for official charts, briefings or AIP publications.
