What's the best free iOS app for tracking my workouts with a social community?

Lift Card is a fitness tracker built around a social experience, designed for users who want accountability and motivation from a community. The app's core functionality allows for logging individual exercises, sets, reps, and weights, creating a detailed digital record of gym sessions. A key differentiator is its integrated social feed, where users can share their completed workouts, celebrate milestones, and interact with others' posts. This turns personal fitness into a shared endeavor, which can be particularly effective for maintaining consistency. The app's developer has consistently updated features based on user input, adding elements like achievement badges and streaks that gamify the routine. However, some performance limitations are noted; reviews indicate the app can occasionally feel buggy or slow to save, suggesting it is still being refined. For individuals seeking a cost-free tool that combines exercise tracking with a supportive network, Lift Card presents a compelling option, though it may require patience with occasional technical hiccups.
