About this app

TrekMe is an Android app to get live position on a map and other useful information, without ever needing an internet connection (except when creating a map). It's ideal for trekking, biking, or any outdoor activity.
Your privacy is important as this app has zero tracking. This means you're the only one to know what you do with this app.

In this application, you create a map by chosing the area you want to download. Then, your map is available for offline usage (the GPS works even without mobile data).

Download from USGS, OpenStreetMap, SwissTopo, IGN (France and Spain)
Other topographic map sources will be added.

Fluid and doesn't drain the battery
Particular attention was given to efficency, low battery usage, and smooth experience.

SD card compatible
A large map can be quite heavy and may not fit into your internal memory. If you have an SD card, you can use it.

Features
• Import, record, and share tracks (GPX format)
• Plan your hikes by creating and editing tracks on the map
• Visualize your recording in real time, as well as its statistics (distance, elevation, ..)
• Add markers on the map with optional comments
• See your orientation and speed
• Measure a distance along a track or between two points

Premium features

• Be alerted when you move away from a track, or when you get close to specific locations
• No limit for the size of maps
• Edit existing tracks (extract or remove segment)
• Fix your maps by downloading missing tiles
• Update your maps
• Use the HD version Open Street Map, with a twice better resolution than standard and better readable texts
• France IGN maps with the "IGN option"
..and more

For professionals and enthousiasts
If you have an external GPS with bluetooth*, you can connect it to TrekMe and use it instead of the internal GPS of your device. This is especially useful when your activity (aeronautic, professional topography, ..) requires better precision and updating your position at a higher frequency than every second.

(*) Supports NMEA over bluetooth

Privacy
During a GPX recording, the app collects location data even when the app is closed or not in use. However, your location will never be shared with anyone and gpx files are stored locally on your device.

Ratings and reviews

Just an amazing app, if it's free maps are enough for you. It let's you download maps for area, and allows you to specify zoom levels, which can save some 80% of space! (I chose only the closest zoom levels, for example). Custom treks work great, and are fully customizeable, gps is also good. The app itself is super lightweight and responsive.

It is not possible to acquire the extended version once and for all, only to rent it by paying recurring subscription fees ad infinitum. In light of the fact that there are competitor products out there that can be bought instead of rented, this milkingware has been replaced with a functionally superior alternative and is consequently being uninstalled as we speak.

Brilliant for France, limited use in UK. IGN make their maps available free-of-charge and a 40km x 40km square can be downloaded into only 300 MB of storage, and that's a super-detailed map that will zoom in to a scale of 1:15000 so shows all the farm tracks. Brilliant value at GBP 13.99 for a year. Doesn't access the OSMaps with footpaths, only the v basic OS maps, so for UK walkers it's best to stick with the OSMaps app and subscription (GBP23.99 pa)
