LocalSend - A brilliant Open source, cross-platform, and free app replaced several apps in my smart phone. Licensed under the Apache License 2.0, it can share files to nearby devices even without internet. Previously I have been using andFTP and Wifi FTP server to share files between my different devices in the same wifi networks. But those apps needs a little configuration in the smart phone, and those who do not have much knowledge in that kind of things, it'll be a little difficult to use them. LocalSend made it so easy.
Linux, macOS, Android, Windows and iOS versions are available.
I don't want to say much more.
Just try https://localsend.org/
