Private device-to-device file sharing fast, native, secure.
Send files directly between iPhones. When networks block P2P, SendTunnel opens a secure, encrypted tunnel so your transfer still succeeds.
Direct P2P first
Peers connect with QUIC for low-latency, high-throughput transfers. No middlemen in the happy path.
Secure tunnel fallback
If NATs or firewalls get in the way, traffic flows through an encrypted tunnel. Content never stored.
Resumable & reliable
Chunked, verified streaming lets you pause/resume and survive flaky networks without re-sending.
Native UX
iOS native UI. System pickers, share sheets, haptics, and dark mode.
Privacy by design
No cloud storage. No analytics by default. Local keys only. Transparent path indicator (Direct/Relay).
Open core
Shared Rust engine with clean APIs. Designed to extend to desktop (and maybe Android!) when you need it.
The tech inside
A shared Rust engine powers the iOS app. We try Direct QUIC first; if the network blocks it, we switch to an encrypted Tunnel.
Looks native where it matters
Screenshots are in the making.. Stay tuned!
Early access coming soon
We'll open the beta very soon, so you can help shape SendTunnel.
