Makes from your iPhone, iPad, Apple Watch and/or Macbook a complete GPS device with detailed topographic maps. Viewed maps will be stored on your device so that Topo GPS can also be used offline. Why should you buy an expensive GPS device if you can install Topo GPS? Topo GPS contains all functions of a regular GPS device for less money, has a much more detailed map, and is more convenient to operate. The accuracy of the position determination is in favorable conditions about 5 m. Ideal for walking, hiking, cycling, mountain biking, sailing, horse-riding, geocaching, scouting, trail running and other outdoor activities. Also suited for outdoor professionals. - Map * To use Topo GPS you need to buy a map. * Official topographic maps of many countries, including Great Britain (OS Explorer), New Zealand and Australia are available as in-app purchase. * Topographic maps are very detailed maps, include height contours and are very suited for outdoor activities. * All maps of a certain region can be made offline accessible using the map download screen. * Easy switching between maps. - Routes * Recording routes, with pause and restart possibility. * Planning routes via route points. * Generating routes * Editing routes * Synchronization with your other devices via iCloud. * Searching routes with filters. * Routes can be organized into folders. - Waypoints * Easy adding by pressing long on map. * Adding waypoints through address or coordinates. * Sharing waypoints. * Editing waypoints. - Layers Layers contain information that can be added to and removed from the map. * Long distance bicycle routes * Mountainbike routes - Coordinates * Easy entering coordinates * Scanning coordinates * Supported coordinate systems: WGS84 decimal, WGS84 degree minutes (seconds), UTM, MGRS, and other country specific coordinate systems. * Coordinates grid layers - Intuitive interface * Clear menu with most important functions. * Different dashboard panels with distance, time, speed, altitude and coordinates. * Clear manual at www.topo-gps.com - Supported file formats: * gpx, kml/kmz, geojson (all also zip compressed), WFS, csv If you are recording a route, the GPS will run in the background.

Verdict
The clearest difference is rating: Topo GPS at 4.5 against mAPP's 3.0. Topo GPS also leads on update cadence (every 3 weeks vs every 5 months) and ratings volume (476 vs 2). mAPP's advantage is iOS requirement (8.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Topo GPS sells 18 in-app purchases, starting at $18.49 per year and mAPP sells 12 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Topo GPS holds the better App Store score, 4.5 against 3.0. That said, the two scores are not equally well evidenced: Topo GPS has 476 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 70% of Topo GPS's written reviews are positive against 48% of mAPP's.
Topo GPS ships an update every 3 weeks, mAPP every 5 months. The most recent releases landed on October 29, 2026 and October 21, 2026 respectively.
