AirMore is the best file managing and transferring app I've ever used. It is 100% free, and I've been using it for over two years. It is an app that allows to transfer music, videos, photos, and other files from PC to iPhone or Android and vice versa. Everything can be done in seconds. How helpfule it is!
Also, on the "More" tab on phone, you are allowed to transfer files from phone to phone. (Also a little bit hard to find this feature, it is useful.)

It is a 100% free screen recorder, and there is no time or size limits to use it. I've used it for many times, and there was no problem, it can produce fairly good screen recording quality no matter I capture full screen or select a region. It can have webcam included while recording, and it allows me to use the built-in editor to add annotations and texts to the recording, which I think is very convenient. Keep moving.
