New features (pro version only):

Custom timers - set your own rest period

Set counter - keep track of how many sets

You can now use 2 additional buttons to add your own rest timers (enable in settings)

Each time you click a rest button the set counter is incremented, you can reset it when you change exercise (enable in settings)

Also re-enabled AdMob adverts for people who prefer to support development that way.

Other additional minor bug fixes, stability and usability improvements
