Understand weeks of training in one screen. Relm keeps your workouts, recovery, nutrition, and progress in one place, then turns that data into insights you can actually act on. TRACK EVERY WORKOUT Build unlimited routines, log sets, reps, weight, and effort, and keep your full training history in one place. Logging is built to be fast so you can spend less time on your phone and more time actually training. ALREADY TRACKING SOMEWHERE ELSE? Import your Hevy, Strong, RepCount or Fitbod history and pick up where you left off. Your training history and progression come with you. UNDERSTAND YOUR PROGRESS Explore exercise history, personal records, progression trends, and detailed performance for every lift. Relm helps you look beyond a single workout and see how your training is developing over time. TRAIN WITH CLEARER DIRECTION Exercise Insights analyze your recent performance to highlight progression opportunities, repeated weight increases, regressions, and other patterns that are easy to miss in a logbook alone. Your Coach Summary then brings those trends together, giving you a clearer picture of how your training is progressing. SEE WHERE YOUR VOLUME IS GOING Visualize weekly training volume across muscle groups with Relm's interactive muscle map. See which muscles you're training most, which you're training least, and how your volume is distributed across your program. TRACK RECOVERY Relm uses available health data to help you gauge how prepared you may be to train and understand how your recovery is trending over time. LOG NUTRITION Calories, macros, and bodyweight tracked alongside your training, so you can see more of what's driving your results. WORKS WITH APPLE HEALTH Bring supported health and fitness data into one place, and save your workouts back out to Apple Health. YOURS, AND OFFLINE Relm works without an account and without a connection. Your training data lives on your device. Cloud backup is optional and off by default. Whether you're trying to build muscle, get stronger, improve your consistency, or better understand your training, Relm gives you every tool you need to stay on top of your progress. Some advanced analytics, insights, and coaching features require Relm Premium. Relm is intended for fitness and wellness tracking and does not provide medical advice.
