Pacer Pedometer Step Counter

A dependable all-around choice for walkers who want a daily step count and the occasional challenge in one place. Setting up a challenge takes about a minute: you create it, send a shared link to friends, family or coworkers, and everyone follows the same leaderboard. No wearable is needed, though Pacer also connects to Apple Watch, Fitbit and Garmin. The step counting and challenges are free on iPhone and Android; Pacer Premium is an optional paid extra for further features and content, so it is worth ignoring the upgrade prompts until you know you want more.
