Its great because the story line is suitably distracting from your newly running misery. My only issue is that if you go into screen lock mode often the app will go silent. You may find yourself dying/ running for the designated 8 minutes only to find its been 10-15 without a word. the app will play all the story line bits youve missed to catch up- but its fairly frustrating/ exhausting! hope they fix this bug soon!
