This app is exactly what I asked for and is super easy to use. I am not a big time computer wizard so I need apps that do what they say do in a straightforward process. This app does just that!

Although there are occasional errors, I was very impressed with the efforts of the developers to receive feedback from users and to improve the inconveniences quickly. I will be using it more often in the future.
