<prompt> Human: My girlfriend and I get shopping and other bits and pieces together and we wanted an easy way to see how much we owed each other. We didnt want to get a joint account as this seems a bit extreme, so we were wondering if there are any apps or services anyone has used that theyve had a good experience with? Were UK based, BTW. Thanks guys!  <response>: Whenever my boyfriend and I want to split something we use venmo. Its pretty easy and you can look back at your transaction history.
