Intervals Pro: HIIT Timer

I was using this app with its original settings of 3 minutes fast and 3 slow and it would tell me when each sessions started and stopped but now it keeps saying adding extra time to each interval and counts up. I can’t get it fixed and have asked for help. I paid for the app too

HIIT is the way to go for fitness for the maximal benefit for the minimal time, and you can combine short bursts of cardio with short bursts of weight. You can designate intervals and rest periods as you like, designate number of intervals or overall time, and can make anything in your home work with this. I have weights, a few pieces of cardio equipment, and do yoga, so can loop around the equipment I have at home with maximal effort and short rest periods and get an excellent workout in 30 minutes. Works in a gym also if you are willing to move to any available piece of equipment or you work out at an unpopulated time. I paid for the upgrade to do this and it is so worth it. It transfers workouts to Apple Fitness seamlessly. Great motivator if you are starting out again!
