If you found Contraction Timer useful, please consider buying this app in order to make a donation.
So your app drawer doesn't get cluttered, this won't show up on your phone except in the Manage Applications menu.
It will remove the donate menu from Contraction Timer (which must be installed) and enable the share menu. If your phone has NFC and is running Android 4 or newer, you will also have the ability to instantly transfer your times to another phone using Android Beam.
Added Move To SD option.
