How SonicDrop works

Three taps, one bump, done. No QR codes, no Bluetooth pairing, no Wi-Fi passwords.

1

Open the app

Sender picks files, taps Send. Receiver taps Receive. Both go to the bump screen.

2

Bump phones together

SonicDrop reads the accelerometer and mic to detect the exact moment both devices collide. No sync needed.

3

Files arrive instantly

A direct Wi-Fi connection opens between devices. Files transfer at full local network speed — no size cap, no compression.

Everything you need, nothing you don't

Built for speed and privacy from the ground up.

100% Private

Files never touch a server. Transfer happens peer-to-peer over your local Wi-Fi network.

Full Wi-Fi Speed

Transfers at your network's maximum throughput — not throttled by Bluetooth or cellular.

No Account Required

Install and share. No sign-up, no email, no phone number. SonicDrop doesn't know who you are.

Any File Type

Photos, videos, documents, APKs, ZIPs — if it's on your phone, you can bump it across.

Instant Detection

Dual-sensor detection (accelerometer + mic) means the bump is recognized in under 100ms.

Works Offline

Same Wi-Fi network is all that's needed. No internet access required during transfers.

Share the way it should feel

Physical. Instant. Private. Just bump and go.
