I've been using this running app for a while now and I have to say it's one of the best out there. The concept of being chased by zombies while running is really unique and helps to keep me motivated. The app itself is easy to use and the in-ear audio prompts are clear and helpful. I definitely recommend trying Zombies Run! if you're looking for a fun and immersive running experience.
