Screencast and screen recording - capture desktop, windows, microphone, and webcam videos.

goCast is a screencasting software. It’s completely free, no trial, no watermarks or time limits. Features: ⭐ Capture a video from tab ⭐ Capture desktop video - whole desktop or a specific window ⭐ Capture webcam only ⭐ Webcam narration (talking head mode) ⭐ Mic or desktop sound ⭐ Supports native WEBM format, as well as MP4 that takes some time to export Please note that screen recording is a resource-consuming task. It takes significant RAM, processor time and can drain a laptop energy. Prepare for recording by closing unnecessary applications and browser tabs. Export to MP4 could be unstable, especially on linux systems.

It's a very great app, and don't listen to bad reviews they are lazy to use it the right way. 1.It's not spyware (google would have taken it down) 2.Stop hating on this great company. 3.enjoy this great app.

Cutie Pie·5 Apr 2021

The app is very simple to operate and decent. If we could have option to save file in our required folder, it would be good. However, this app deserves a 5-star.
