I paid for "premium". But this app is beyond frustrating. Two key issues, but the one that really gets me all worked up is how terribly difficult it is to delete anything. If you added an extra interval by mistake, you are STUCK! Also, if you want to reduce the proliferation of unused timers ... can't delete those either! For "balance" they have a website that shows you how to do it. I read the online manual, and still can't get it to work. It really should NOT be this complicated or difficult.
#2: This app can't add warm up or cool down sections that don't repeat themselves. The only thing that does not repeat is the "Countdown". But if you want say 5 intervals (30 second sprints followed by 2 minute walks), and end with a cool down, this app includes the cool down as part of the whole thing that repeats itself 5 times. Why do I want to "cool down" 5 times?!? Frustrating.
CONCLUSION: Until the 2 issues are resolved, I can't recommend this app.

Very Useful

I love this app. It's very useful and versatile. You can create your own timer with the parameters you need in addition to using the pre-programmed timers provided. I do not mind the ads at all and they are, for the most part, unobtrusive. Thank you for creating this app, it has been and continues to be a huge help for me.

For traditional martial arts it’s one of the Best

So you like to do Chi gong or Nei gong stances or sitting postures. You may have 2 or more stances or postures you want to do in consecutive order. This app is for you. You can make a timer for setting up for your first posture the timer of the first posture in another time or after to give you time for the next posture for example (:20,3mins,:15,3mins)
20 seconds to set you up , 3 mins for the first posture then another 15 second timer to give you time to change into the next posture, then 3 mins for the second posture. This is just a example for extreme traditional martial arts enthusiast or professional athletes that wants to cut right to the chase while in airplane mode all business.
