PLEASE NOTE: The duplicate feature currently only works with iOS devices, and not on the Android. If you'd like to see it added to the Android client, please vote for it HERE.
To copy a record you must touch and HOLD on the record you would like to copy until the Delete/Print/Duplicate boxes appear. Select "Duplicate" to make a copy of this record. (This is helpful when only a few answers may change and you don't want to fill out the whole form again.)
