The app maps your sessions and you can post to social media. It’s free, though there’s a $5 per month upgrade (Zen Unlimited Pass) which adds additional features like curated playlists and the ability to track calories and distance. While you can optionally play music, because there are lots of empty spaces between the voice acting, this app is best for folks who like listening to podcasts while they exercise. What’s nice is the exercise instructions are integrated into the narrative. The app is free, but a $6 per month subscription gets you additional zombie adventures after reaching your first 5K milestone. And while there are no in-app purchases or ads, the interface is bare-bones and boring, with no visual flourishes or extra features. And there are no tracking or mapping features to chart your progress. Unfortunately, every workout within a level is the same, with the same mix of walk and run intervals from the first day to the last, so it doesn’t really build you to your goal in an incremental way. On the other hand, you can tweak the plan on the fly during a workout; you can skip the walking intervals with a tap if you want more running, but you can’t skip the running intervals. For a one-time fee, you can unlock more features like the ability to make custom workouts and see more stats on your progress. Here can pick a general plan, like the 4-week Get Started plan, and customize it with details like how often you can run each week. In addition to the Coach, there are guided runs narrated to help you get better and try different kinds of runs. The actual runs are repetitions of walking and running with a steady throttling until you are running for 20 minutes or more. The actual interface is plain to the point of downright ugly, but it’s functional, and you can skip any interval (walking or running) at any point. When the workout is over, the log tracks a slew of information including a graph of your pace.
