Explore places and navigate safely during your outdoor adventures and travels around the world. The app offers unlimited map downloads and biweekly updates. OpenStreetMap-based, volunteer-made, privacy-first, 100% offline, and 100% free. OFFLINE: The app works 100% offline — including search and navigation. You can explore the map and navigate without an internet connection, saving on mobile data and roaming fees. And with no background data transfers, your battery lasts much longer. FAST: Zooming, search, and route calculations work noticeably fast. DETAILED & UPDATED: The maps are rich in detail and refreshed twice a month to reflect real-world conditions. Unlike many well-known competitors, they include building labels, benches, hiking paths, and other helpful information. OPENSTREETMAP-BASED: OpenStreetMap is a wiki-style world map built and maintained by millions of volunteers — locals who know their areas best. This community effort results in highly detailed maps, often more accurate than commercial ones in less-mapped regions. Organic Maps updates its data from OpenStreetMap every two weeks, keeping your maps fresh and reliable. And if you notice something missing, you can add it to OpenStreetMap and help improve the map for everyone. PRIVACY-FIRST: We don’t collect any data or identifiers. This means there’s no risk of data leaks and no distractions like ads or noisy notifications — just a clean, private map experience. IMPORTANT FEATURES EXPLORE PLACES: Search by address, name, or category, discover millions of POIs, and view detailed information such as opening hours, Wikipedia articles, wheelchair accessibility, and other helpful details. All available offline. GPS NAVIGATION: Enjoy voice-guided, turn-by-turn directions. Create walking, hiking, cycling, or driving routes — including routes between cities, countries, and multiple waypoints. Find the best routes for your metro journeys and commutes. CarPlay is supported. HIKING & CYCLING TRAILS FROM AROUND THE WORLD: Enable special map layers to discover popular hiking and cycling routes worldwide, all sourced from OpenStreetMap. Switch between layers to see colored bike and MTB routes, as well as official hiking paths. PUBLIC TRANSPORT: See public transport route numbers at stops. Live transport schedules and routing are currently in development. MAP STYLES: Choose map layers that fit your activity — Outdoors, Contour Lines, Hiking, Cycling, or Metro/Subway. TRACK RECORDER: Record, import, export, and share your routes and favorite places. Supports KML, KMZ, GPX, and GeoJSON formats. WIKIPEDIA ARTICLES: Explore Wikipedia articles for places you discover on the map. Type “?wiki” in the search to find all places with Wikipedia articles. MAP EDITOR: Contribute to OpenStreetMap by adding missing places or editing the map directly from Organic Maps. DARK MODE: Switch to a dark theme for comfortable viewing at night. iCLOUD SYNC: Easily back up and sync all your bookmarks and tracks via iCloud. Try the app — it’s 100% free, ad-free, fast, and fully offline. Enjoy a fast, reliable, and private map experience, and share it with others!

Augview Compass is a high-accuracy compass application supporting: • Compass Deviation Error measurement & correction • Map navigation compass • Augmented Reality compass • Map marker tracking • Works in all orientations Have you been frustrated by Compass apps that claim to be accurate, but turn out to be hopelessly inaccurate or not work at all in certain device orientations? This was one of the drivers for us to create the Augview Compass app - a compass app that is more accurate, that works in all orientations and that provides both a map view and an Augmented Reality (AR) view for ease of use. The accuracy improvement is achieved by first measuring the Compass Deviation Error, and then deriving a function that provides a correction for any observed bearing. Compass Your phone or tablet incorporates various sensors that may be used to determine its location, its orientation and the way in which it is moving. We can compute the compass orientation by using a combination of these sensors. The magnetometer is the primary sensor used to detect magnetic fields. It measures the Earth's magnetic field in three dimensions (X, Y, Z axes) and helps determine the direction relative to Magnetic North. However, the Earth's magnetic field is relatively weak, and the magnetometers used in our phones show high levels of signal noise, when compared with the Earth’s magnetic field strength. To reduce noise in the outputs, filters and smoothing algorithms are used. To improve the accuracy, outputs from the accelerometer and gyroscope are also integrated using a technique known as sensor integration. Using the outputs from these three sensors, filtering algorithms and sensor fusion, we can determine a bearing relative to Magnetic North. The Magnetic North Pole is the point on the earth’s surface at which the planet's magnetic field points vertically downward. The magnetic north pole moves over time. As of 2024, its location is 86° N, 142° East and modelling predicts that by 2025, it will have drifted westward to 138° East. True North refers to the geographic North Pole, the point at the top of the Earth’s axis where all lines of longitude converge. This is the northern point of the Earth’s axis of rotation. True North is essential for mapping and GPS systems, as it provides a consistent reference for determining direction regardless of magnetic variations. The angular difference between Magnetic North and True North is called magnetic declination. This angle varies depending on where you are on Earth and because the north and south magnetic poles move, magnetic declination at a fixed point on the earth’s surface changes over time. Fortunately, there are formulae and web sites that can provide the declination value for any given date and geographic location. To indicate whether a bearing is relative to True North or Magnetic North we use the symbols °T or °M. Compass Calibration The operating system running on your device, allows you to Calibrate the magnetometer, to help reduce error, and to compensate for: • Sensor Drift • Local Magnetic Interference • Sensor and phone manufacturing issues To help reduce these issues, manufacturers recommend rotating the device about each axis, and/or rotating the device in a figure of 8 motion. Augview recommends a systematic approach where you: • Face north to be parallel with the earth’s magnetic field flux lines (to get maximum and minimum magnetic field strengths) • Rotate the device slowly about each axis twice • Hold the device flat and rotate about the vertical axis twice Calibration should be performed regularly, and especially after charging the device or leaving it near other electrical devices. Compass Deviation Error This is the error remaining after magnetometer calibration has been performed. The Augview Compass app incorporates a procedure for measuring and compensating for compass deviation error.
