Why We Chose It: MapMyWalk is one of the most comprehensive free apps online. With features like audio feedback, labeled routes, easy-to-see maps, metrics tracking, and data analysis, this app is one you should try.

The Walkmeter app is available for GPS-capable iPhones and iOS devices. The basic version is free, with Elite upgrades and different voices for a small charge. Many of the advanced data features require the Elite upgrade. There are no additional membership fees required.

Walkmeter is the most advanced application for walkers and hikers. Built for iPhone, iPad, Apple Watch, and iCloud, it makes your iPhone a powerful fitness computer — with maps, graphs, splits, intervals, laps, announcements, zones, training plans and more.

The Health app gathers health data from your iPhone, Apple Watch, and apps that you already use, so you can view all your progress in one convenient place. Health automatically counts your steps, walking, and running distances. And, if you have an Apple Watch, it automatically tracks your Activity data.
