I just completed my first sprint tri using this app as my primary training schedule. I really loved this app! You can adjust your weekly day off as you go and change the schedule if you need to. The only thing that was annoying was that you cant change the workout after the day has passed. So if you change your workout last minute make sure you adjust the schedule in the app before the end of that day! Definitely recommend this for first time triathletes!
