Riven: Auto Workout Tracker

Your dream physique is built on muscle failure. We turn your Apple Watch into an automatic workout tracker. It starts your sets, counts your reps, names the exercise and measures how close each set came to muscle failure. No buttons, no phone, no logging between sets. FULLY AUTOMATIC ◆ Starts sets: Riven sees when a set starts and when it ends. Nothing to start or stop. ◆ Counts reps: every rep is counted from your wrist as you do it. ◆ Names exercises: 100+ exercises supported, and the most common lifts are recognized on their own, including bench press, squat, curls, rows, pulldowns and lateral raises. ◆ Measures muscle failure: the moment you rack the weight, your set gets a score from 0 to 100 for how close you came to muscle failure. ◆ Scores every muscle: see which muscle groups reached muscle failure in each workout. ◆ Syncs with Apple Health: sets, reps, exercises and scores are saved on their own. SHARE YOUR WORKOUTS ◆ Post to the feed: share any workout, with the muscles you took to muscle failure, and get kudos and comments from other lifters. ◆ Weekly league: see where your average muscle failure score ranks against lifters worldwide, and join challenges. ◆ Your choice: make your profile private any time, and report or block anyone. WHAT IS MUSCLE FAILURE? It's the rep you can't finish. Muscle grows when you train close to it, but most lifters stop a few reps short and never know it. Riven tells you after every set, in colors you can read at a glance: Red: stopped short Orange: working Yellow: near muscle failure Green: muscle failure HOW IT MEASURES MUSCLE FAILURE Your Apple Watch reads your wrist's motion 100 times a second. As a muscle tires, your reps slow down. Riven measures that slowdown, called velocity loss, which is the best-studied sign of fatigue in strength training. Heart rate is saved to your log, but it isn't part of the score. NOTHING EXTRA No camera, no barbell clip, no chest strap. Works with barbells, dumbbells, cables and machines, using the watch you already wear. REQUIREMENTS Apple Watch Series 6 or later (watchOS 10+), paired with an iPhone on iOS 17 or later.
