Senzu is a fitness tracking app built around one idea: Training is not just about pushing harder. Recovery matters too. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://senzu.online/privacy We believe progress comes from rhythm, not pressure. That means recording your workouts, understanding your trends, and leaving room for recovery when life gets in the way. With Senzu, you can: Log strength workouts quickly Track exercises, sets, reps, and weight with a clean and simple flow. Record cardio sessions Log duration, average heart rate, and distance for running, cycling, rowing, and more. See your training trends clearly Follow workout frequency, focus distribution, strength progress, and cardio insights over time. Generate shareable training reports Create polished training report images by month, year, or custom date range. Protect your rhythm with Senzu Days Inspired by the Senzu bean from Dragon Ball, a Senzu Day helps keep your training record going on days when you do not work out. It does not count as a workout. It is not something you can buy. It simply makes room for recovery. Senzu is not here to push you harder every day. It is here to help you build a rhythm you can actually live with. Train well. Recover well. Live well.
