The current version of Date Calculator is 1.1.9. This version fixed an exception caused by the save data button. This button allows the user to set the data that the app starts with.
The Home key on the phone does not clear the app from memory so if you use the Home key to close the app the saved data will not be used when the app is restarted.
Date Calculator is financed by Google AdMob advertisements.
