I am not a born runner, I hardly even like to jog but Intervals made it an easier transition for me. With the interval timing ability, I can set the time I want to spend running, walking, recovering, and even the total length of time I want the workout to be. It’s so easy to program.

This app stays in sync and is really efficient. It really takes care of your interval needs

With the absence of great couch to 5k apps that standalone on the Apple Watch this app is a godsend and a must have!

Does everything I need for custom interval workouts all on my watch, no phone required.

Works great with series 0 Apple Watch, I am able to run without my phone with Intervals on my watch
