I do interval training and needed something to track me, without the need of starting and stopping a timer. I currently have 6 interval timers saved, and this has made all the difference for me! My workouts are more streamlined and I don't need to worry about my heart rate dropping too low between sets. You can set prep time, length of each set, and rest time in between, and you can save each timer by its own name or purpose (ie: Warmups, Warmup Sprints, etc). This app is perfect!

Great timer app! Very easy to set my intervals for weight lifting, battle ropes, kettlebells, jump rope, or any other activity! Definitely worth the money to remove the ads too! Looking forward to future updates! 11/2025: Still love it. Worth every penny. I had to switch phones, and thankfully, logging in to my Internal Timer account brought over all of my saved workouts effortlessly.

Really nice App for me as an athlete especially with interval sprints and other workouts. I recently started doing pool workouts and in order to remember what exercise is next I think it would be cool if you had a way to name the sets for example set 1 would be Tuck jumps and so on and so forth. It'd be really cool if this could be implemented in the future and make the app even better!
