firs bug . . when you select the minutes there is no the option for the 0 so it means that you can't have a repetition under then 60 sec i think for the kcal you sholud make \efore 6 differet choice 1 to 100 kcal 2 to 200 kcal in this way could be much easyier! can you also put an option take off the vibration when we push shake!! btw I'm gonna use it!!the best one so far!
