Manage your time wisely at the gym. That "two-minute rest" turned into five. Again. Research shows rest duration directly determines whether you're training for strength, hypertrophy, or endurance — and most people just wing it. Complex fixes that. SCIENCE-BACKED REST TRACKING Pick your training goal — Strength, Hypertrophy, or Endurance — and Complex sets your optimal rest window based on peer-reviewed research. During your workout, the timer shifts color in real time: green when you're in zone, amber when you're drifting, red when you've over-rested. No guessing. No scrolling. Just data. EIGHT PURPOSE-BUILT TIMERS One app for every training style: Set Workout — Dual-clock system tracking workout time and rest periods with live drift detection and post-workout consistency scores. Intervals — HIIT and Tabata with customizable work/rest/rounds and preset configurations. EMOM — Every-minute-on-the-minute with configurable intervals and work windows. Rounds — Boxing round timer with fight/rest cycling for boxing, speed rounds, and Muay Thai. Countdown — Simple countdown with quick-select durations and custom wheel picker. Stopwatch — Count-up timer with centisecond precision. Lap Timer — Split recording with fastest and slowest lap highlighting. Yoga/Flow — Sequence-based pose holds with named poses, adjustable durations, and calm transitions. POST-WORKOUT INSIGHTS After every Set Workout, see exactly where discipline held and where it slipped. Average rest, zone hit rate, rest period bars color-coded against your goal. Two lines of data, not a lecture. COMPLEXES — SAVE YOUR SETTINGS Finish a workout and tap Save as Complex to capture your exact configuration as a reusable template. Organize templates into folders.
