Whether you need to send gigabytes of high-definition videos, album's worth of photos, work documents, audio files, or full applications, SiuHay makes device-to-device transfer seamless, reliable, and ridiculously fast.

Lightning-Fast Local Speeds

SiuHay transfers files directly between devices over your local network, achieving speeds up to tens of times faster than traditional cloud-based tools.
