How SuperBeam Pairs Devices and Transfers Files

Updated

SuperBeam pairs two devices by QR code, NFC tap, or a manual sharing key, then sends files over a direct WiFi connection. The QR code and NFC options are in the free version; the manual sharing key is a PRO feature. Once paired, you can send individual files or entire folders, and the receiving device does not need to approve each connection manually.

The pairing step

SuperBeam's own description is that you "do not have to memorize passwords or search for other devices." Instead, pairing happens one of three ways:

  • QR code — one device displays a code, the other scans it with the built-in QR scanner.
  • NFC — hold the two devices together so the near-field connection passes the pairing details.
  • Manual sharing key — type a key on the second device. This option is listed under PRO features.

In practice, the QR route is the one to try first: it needs no extra hardware and works on any Android phone with a camera. NFC only helps if both devices support it. The manual key matters when a camera is awkward to use or NFC is unavailable — for example, passing a file to a phone whose screen is cracked and hard to scan.

The transfer step

After pairing, SuperBeam opens a direct WiFi link between the two devices. The site describes it as using "WiFi direct technology or whatever WiFi connection available," which is why it can move data quickly without going through a router or the internet.

From there:

  1. Pick the files — or a whole folder — on the sending device.
  2. Confirm the send. The site notes there are "no more clicks and manual approvals for connections," so the paired device should not need to accept each item separately.
  3. The receiving device saves the files. Folder sends preserve the folder hierarchy, but that is a PRO capability.

What the free and PRO versions each allow

Capability Free PRO ($1.99)
Pair by QR code Yes Yes
Pair by NFC Yes Yes
Pair by manual sharing key No Yes
Android-to-Android transfer, unlimited files Yes Yes
Send/receive with a computer via SuperBeam for PC No Yes
Send entire folders with hierarchy preserved No Yes
Share with more than one device at once No Yes

The free tier is enough to test whether direct WiFi transfer works between your two phones. PRO is the upgrade to consider if you need computer transfers, folder structure, or multi-device sending.

If transfers feel slow

SuperBeam's FAQ gives one concrete fix: turn WiFi off on both the sender and receiver before you start. That forces the app into direct mode, which the site says allows "much greater speeds." The same FAQ puts typical speeds at 20–40 Mbps, with some high-end devices reaching around 75 Mbps — so if you are seeing far less, the direct-mode trick is the first thing to try.

What to check before you start

  • Both devices run Android 2.3.3 or later (the free version's stated minimum).
  • For computer transfers, you need the SuperBeam for PC app, which the site lists as compatible with Windows, Mac, and Linux — and that requires PRO.
  • If you plan to rely on the manual key rather than QR or NFC, budget for the $1.99 PRO purchase.
