Displays immersive 3D terrain and satellite imagery, with route planning and simulated GPS for pre-hike scouting. Built by Chess Vortex Games as an Android maps-gps app, it combines OpenStreetMap route and POI data with high-resolution terrain rendering. Key functions include offline map downloads, real-time GPS tracking on topographic maps, and custom rectangular map creation. The app fits hikers, trekkers, and mountaineers who need detailed terrain previews and dependable navigation in areas without mobile data.

What can you use it for without leaving your desk?

Hedda lets you preview and test routes using its simulated GPS mode and satellite imagery, enabling virtual scouting before a trip. The app supports setting a simulated position and viewing the landscape in 3D, which the developer highlights as a way to preview approaches. Users can select a rectangular region anywhere in the world to request a custom map for later field use.

How accurate is the terrain and GPS presentation?

The app combines OpenStreetMap data for routes and points of interest with high-quality 3D terrain and satellite layers, which helps show ridges and valleys visually. It also offers real-time GPS tracking so you can see your exact position on topographic maps while navigating. The reviewer's observation is that the layered presentation prioritizes visual clarity of steepness and ascent for route comparison.

Does it work when you lose mobile signal?

Offline map downloading is built into the tool, allowing you to store specific map regions on the device and use GPS navigation without mobile data. The app is available for Android via the Google Play Store and does not require device modification to download and view offline tiles, which suits field use where connectivity drops are common.

Clear purpose with reliable offline capability; suited to detailed pre-trip planning

Hedda targets outdoor users who need spatial detail and pre-hike verification rather than casual waypoint marking. It supports route analysis and simulated scouting, and users must ensure their chosen use follows platform terms and local regulations. For those who need visual depth in terrain and a way to prepare routes ahead of time, the app serves that role effectively.
