I love zombies, and Ive been trying to motivate myself to run regularly since I first did C25K last year. I had a bit of a gap so I picked up this and the companion Zombies Run 5K app (which could use some updates to bring it up to iOS10 and integrate with HealthKit, but is still useful). The story is a good way to zone out and get your run (or walk) in. The main app does integrate well with HealthKit. The watch app just had an update to make it a little more feature full. I love all the geeky references as you go through the missions.
