Video Player Companion is a free Android application developed by SM Software that allows users to transfer video files from their Android phones to Samsung Galaxy/Gear smartwatches. With this app, users can enjoy their favorite videos on their smartwatches wherever they go. Currently, Video Player Companion supports Gear S2, Gear S3, Gear Sport, and Galaxy Watch.

To transfer video files, users need to install Video Player Companion and enable Bluetooth on both their phone and smartwatch. They should then run Galaxy Video Player on their smartwatch and select a video and/or subtitle file on their phone. From the list of applications, they should choose Video Player Companion and the transfer progress will appear on their smartwatch.

It is important to note that this app uses Samsung Accessory Protocol (SAP) to transfer files. If users do not have a Samsung phone, they must install SAP before transferring any files.

Overall, Video Player Companion is a great tool for Samsung smartwatch users who want to enjoy their favorite videos on the go. It is easy to use and offers a seamless transfer experience.
