Operating System: Windows Phone 7
IOU is a Windows Phone 7 app which allows the users to keep a track of what he owes to others, and what others owe to him. There may be times that someone borrows something from you, and with time, you forget about it. Such things can be anything from cash to kind, including DVDs, game CDs, kitchen appliances, or dresses. You can avoid such a situation by using the IOU app available for Windows Phone. All the transactions can be seen on your overview screen. Items that other people owe you are indicated with an arrow on the left, while items that you have to return to others are indicated with an arrow on the right. It acts like a visual indicator and is quite helpful.
While adding new entries, you have to fill the name of person and the item or amount of money you have given or taken, along with other details. There are various color options in the settings of the app, which allow you to enjoy the stored data. The application also changes color as you change the theme of your Windows Phone 7-based mobile. Once you have received or given an item that you owe or other people owe to you, you can delete it completely.
All in all, even though it is in it's initial stages, IOU is an ideal and useful app. And overtime, with a few updates, it can become even better. This is a practical application which can be of use to consumers on daily basis. And the best thing about the app is that it is absolutely FREE to download.
