After using the scrum app during our match official group sprint sessions, I've made a few tweaks to the app. Update from the stores to get these improvements: Each time you choose a mode, the playlist is now limited to 10. There are more than 10 videos (and next update will include some new ones) but each time you choose a mode you get a random selection of only 10. Text on the answer buttons is now readable on iPhone 6 :) If you haven't tried the app during training yet - I thoroughly recommend it. What we did: Warmed up as usual Paused running and each person using their own phone or tablet, watched a set of videos in normal mode, noting the score. Then we did our sprint session, running till fatigued. Paused again and each person using their own phone or tablet, watched a second set of videos in normal mode, noting the score. Used the score difference as an incentive - If you scored 10 on the first attempt and 8 on the second, you ran 2 more shuttles. This
