Rest Timer is a free Android app developed by Lucidiem, designed to help you time the rests in your fitness routine. Whether you're weight-lifting, training, or doing High Intensity Interval Training (HIIT), this app allows you to adjust the amount of time and sets to suit your specific needs.

With Rest Timer, you can easily customize your rest periods, reps, and sets. For those focusing on hypertrophy, the app recommends rest periods of 1 to 2 minutes between sets to help you get bigger quicker. If you're aiming to increase muscular endurance, the app suggests rest periods of 45 seconds to 2 minutes between sets.

One of the key features of Rest Timer is its flexibility. You can adjust the number of sets and rests, set a custom interval time, and even modify the timer while it is running to give yourself extra time if needed. The app also offers background notifications and optional notifications, so you'll be notified when it's time to begin your next set.

Rest Timer is the perfect companion for your gym workouts, whether you're at home or in the gym. It provides a simple and convenient way to time your rests, reps, and sets, helping you stay on track with your fitness and training routine.
