Trail Trace: GPS Offline Maps

Keep a record of the paths you actually travel. Trail Trace combines a GPS recorder, offline maps, named places and GPX files for walks and trips. RECORD WITH THE SCREEN OFF A foreground location service records GPS points while the app is minimised or the screen is off. The recording screen shows distance, elapsed recording time, point count and reported speed. Pause when you take a break, resume when you continue, then finish and save the route. A resumed recording starts a separate segment, so the pause is not drawn as a made-up connecting line. KEEP CONTROL OF RECORDING With notification permission, the ongoing Android notification offers pause and stop actions. You can always stop inside the app. Precise location and an enabled GPS are needed to record; permission is requested when you use the feature. Denying it leaves your saved maps and history available. Recording does not start automatically after a phone reboot. A WORLD OVERVIEW INCLUDED The built-in world map opens offline and shows an overview of land shapes. Move around it, use pinch zoom or the map buttons, and display a recorded route. This overview is for geographical context. It does not contain the street and trail detail of a regional map. BRING YOUR OWN REGIONAL MAP Download a Mapsforge .map file for the area you need before travelling, then select it with the Android file picker. The app imports a private copy and renders it on your device; after import, viewing that file does not need a network. Regional imports support files up to 1 GB. Downloading the original file or opening the external map website needs a connection. Coverage and detail depend on the file you choose. SAVE PLACES WITH NAMES Save a fresh location with a name: a meeting point or the start of a walk. Your places stay in a list. Open one on the map or share its coordinates using another app. The location panel shows coordinates, estimated accuracy and how long ago the latest fix arrived, so an old location is not silently presented as a new one. RETURN TO ROUTE HISTORY Finish a nonempty recording to save a separate route. Review its date, distance, duration and number of points, give it a new name and open it on the map. Individual removal requires confirmation. Choose one of four track colours and a light, dark or system interface theme. IMPORT AND EXPORT GPX Import adds route geometry to history without replacing the current recording. Different segments stay separate on the map and in the distance calculation. Export a saved route or the current recorded track to a GPX file through Android's file chooser. GPX imports accept UTF-8 files up to 4 MB, 20,000 points and 100 segments. Track and route geometry is supported; elevation, original point times and waypoints are not imported. Imported geometry has no recorded duration. A GPX file contains coordinates, not a complete backup of settings and saved places. LOCAL DATA AND ADVERTISING Routes and places are stored on your phone without a developer account or app-operated cloud sync. Their contents are not supplied as ad targeting parameters. Shared GPX and coordinates can disclose precise places; check the recipient before sending. Export important tracks before clearing app data or uninstalling. There are no purchases or subscriptions. Banner and app-open ads are used outside protected activity; full-screen ads are blocked during recording and its pauses. Optional rewarded viewing can provide 24 hours without ads after confirmation. Core maps, recording and history never require watching an ad. Network loss does not block local maps or GPS recording. GPS reception, device settings and battery restrictions can affect a track. Filtering reduces some implausible jumps but does not guarantee physical accuracy. Trail Trace does not calculate road routes, search addresses or provide turn-by-turn navigation. Lumetra Mobile: https://lumetra-mobile.com/ Support: [email protected]
