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 in-app purchases: PezCA at none against Topo GPS's 22. PezCA also leads on rating (5.0 vs 4.5). Topo GPS's advantage is ratings volume (476 vs 3) and device support (5 vs 2). On price, update cadence, ads and iOS requirement there is nothing between them.
