AirPortal is an app that allows you to transfer files between any devices, including PC, mobile and tablet, no matter what system they run - Windows, Android, iOS, macOS or other platforms. As long as your devices have the access to the Internet, you can upload files from one device via AirPortal and then download them on any other devices also via AirPortal. The whole process needs no login or registration. All you need to do is uploading the file and memorize the four-digit code given, which is required when you want to retrieve the file, or you can simply scan the QR code shown on screen to start downloading.
