I am working with health care workers in Kenya. We are going to be creating patient education videos on tablets- Android based- and have very limited access to wifi. These are not going to be very sophisticated videos but they do serve an important purpose. Some of the health care workers may have access to laptops- but not all. Does anyone have any suggestions for a good video editing app for androids that seems to work well and is free or really inexpensive? I would be most grateful for suggestions.
