If you find yourself wishing you could send large files or a large group of multiple files such as photographs to another user standing right in front of you without having to mess with e-mail or a bunch of texts, Superbeam could be just what you're looking for. The app is easy to use with the user on the source phone choosing all the files they want to send to a friend in any app that supports sharing. The user then only needs to press the share button and select Superbeam.
The app generates a QR code and starts a connection for NFC enabled devices if available. The user of the destination device will then launch Superbeam and take a picture of the QR code that the app generated on the source phone. If both devices are NFC equipped, the users can also tap them together to start the NFC transfer.
If both devices are connected to the same Wi-Fi network, the app can use Wi-Fi to transfer the files if that's what the user wants to do. One potential downside is that the data transfers are said to be quite slow at only around 15Mbps on a fast corporate Wi-Fi network. The app also supports transferring files over Wi-Fi Direct.
The only potential downside to using Wi-Fi Direct is that the user would have to configure some settings before sending data. Data transmissions using Wi-Fi Direct are said to be in the 25 Mbps range. The app is available for download on Google Play right now.
