Measure Map is an application that supports a distance calculator to find out the distance between two or more points anywhere on the earth. In other words, the distance between A and B. Click once on the map to place the first marker, and then click again to position the second marker. The distance between the points will then be displayed. You can also build up a series of locations to find the total distance. A minimum of two markers are required to measure distance and a minimum of three markers to measure area. - Distance results will be output in meters, kilometers, nautical miles, feet, miles, and yards. - Area will be output in meters², kilometers², feet², nmi², yards² and acres. - Save and view measurement sessions - Import list coordinates to draw measurements on the map. - Import and export KML, KMZ, and CSV files. - Edit coordinates of measurement and Share them with other devices. + Support to quick change map type: normal, satellite, terrain, hybrid + Support UTM, MGRS, and VN-2000 coordinates. + Support coordinates at your position - The application uses some icons and designs on the website: # icons8.com # freepik.com # clipartbro.com # Pixeden.com # logo reference from alpha.wallhaven.cc/wallpaper/379827 - The Application use third party open source from website: # github.com/scalessec/Toast-Swift # github.com/Alamofire/Alamofire # github.com/volkerv/GeoCoordinateConverter # github.com/AssistoLab/DropDown # github.com/yukiasai/Gecco tutorial # github.com/jonkykong/SideMenu # github.com/groue/GRDB.swift # github.com/CosmicMind/Material # github.com/hackiftekhar/IQKeyboardManager # github.com/tobihagemann/THLabel # github.com/bizz84/SwiftyStoreKit # github.com/Orderella/PopupDialog # material.io/tools/icons/ --- Thank you for using my app!

Verdict
The clearest difference is rating: Measure Map at 4.7 against GCTools's 3.1. Measure Map also leads on review sentiment (79% vs 40%) and ratings volume (5.3K vs 13). GCTools's advantage is ads (none vs shown) and iOS requirement (9.2 vs 16). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. GCTools sells 7 one-off in-app purchases and Measure Map sells 4 in-app purchases, starting at $7.99 per year. Whichever you choose, the download price is not the number that matters.
Measure Map holds the better App Store score, 4.7 against 3.1. That said, the two scores are not equally well evidenced: Measure Map has 5.3K ratings behind it against 13, so its average is the more settled of the two.
