A few months ago I had my right arm injured. The doctor recommended several exercises as part of the treatment. They were like "do this for 15 seconds, 10 times". And quite often I got distracted and lost the count. What a iOS developer can do? Write an app, of course! So here you are: an app for repetitive, timed activities.
