What is Dropp?

Dropp is a modern cross-platform dropzone that keeps your files accessible across all your devices. Drag files to your shelf on macOS, then click to sync them to the cloud—they'll be available on your Android phone and other devices. Unlike traditional file transfer methods, Dropp gives you a persistent shelf with the ability to quickly move files between your devices.

Currently working for macOS and Android, with Windows support coming soon.
