As others have said, its got bugs

Two bugs: you cant login with ZombieLink, which isnt that big of a deal if youre just using this for Couch25k. It kinda ruins the potential for me to head over to the Zombies Run app after this though, since all of my work will be nullified.

Second bug: the program stops sometimes. Just keep a mental note of how long 30 seconds is and, if it feels like 30 seconds have come and gone, the app probably crashed :/

Other than that, great concept, great production value, great execution. Just has a few bugs that I wish theyd fix.

I will say this Couch 2 5k is a little less structured than other Couch 2 5k programs; for example, after week 3, it just sets you on Freeform Runs, wherein youre told to just run and walk as much as you feel comfortable doing which, if youre lazy, youll probably not push yourself running as much as you should. The VERY FIRST mission you do, if you select that you havent played a Zombies Run game before is unforgiving compared to Week 1 Workout 1s mission.
