IOweU is described as 'Free IOU tracker for money, borrowed items, favors, and tasks. Where most expense splitters only handle shared money, IOweU covers anything people owe each other, and either side can create the IOU — you don't have to wait for the other person to log it' and is a Budget Manager in the business & commerce category. There are three alternatives to IOweU for a variety of platforms, including Android, iPhone, Android Tablet, Web-based and HUAWEI AppGallery apps. The best IOweU alternative is Splitwise, which is free. Other great apps like IOweU are Tricount and Settle Up.
