Fervu scores every workout (169 exercises, from lifting to yoga and dance) and puts you on a weekly scoreboard with your friends. On Sunday someone wins; on Monday everyone starts from zero. Then it tracks you against yourself: an activity score from 0 to 100, records per exercise, age-graded running times, VO2 max and resting heart rate from Apple Health or Health Connect. Group vs group duels, 16 levels. Free, no ads, no feed, no tracking. English, Portuguese and Spanish.
