Does the job, mostly

However, if the times youre adding are also on your phone (like splits or intervals) you cant go back and forth to add them because as soon as you leave this app it zeroes out your time. The first time I had to remember the total each time I left to add the new time to. Next time Ill remember to write them down first ... but I shouldnt have to.
