Because this is a direct, zero-cloud P2P tunnel, we both need to be in the app to run the transfer.
📲 For iOS Users: Please keep Lahar open on your screen and plugged into power until the transfer finishes for maximum speed.
⚡ Tap to get it, and we'll start the transfer right away:
Installed? Open the transferAlready have Lahar? Update it first — this file needs the latest version. Then tap the link again.
New to Lahar? See how it works ↓
A Lahar link ends in a long code after #. Ask the sender to share it again, or copy the whole thing.
Hours of 4K video, a whole photo library, a full backup. Lahar connects your phone directly to theirs and moves the file across — no cloud upload, no size limit, no account.

Under the hood, Lahar opens an encrypted connection over the same distributed network BitTorrent-style tools use to find peers — it just hands you a link instead of a torrent file.
Any file, any size. Lahar reads it straight off your device — nothing gets copied to a server first.
You get a link the instant sharing starts — before the transfer even finishes preparing.
Text it, WhatsApp it, email it. The link is just an address — it carries no data of its own.
It opens Lahar on their phone (or shows them where to get it), and their phone pulls the file straight from yours, byte for byte. You both keep Lahar open while it moves.
Send a 400 MB clip or a 40 GB video the same way — Lahar doesn't measure your files against a quota.
Every connection is end-to-end between the two devices involved. There's no server in the middle to leak from.
Not a free tier. There's no storage to bill for, so there's no upgrade prompt waiting for you either.
Pair with someone once and send to them again without a new link — and their phone lets them know when you're sending.
Watch bytes move in real time, both sides — and get a confirmed, hash-verified receipt the moment it lands.
Your link is ready the moment you hit share — before Lahar even finishes reading the file.
Lost signal, a phone call, a switch to another app — the transfer pauses and carries on from where it was, not from zero.
The file goes straight from your phone to theirs, so you both keep Lahar open while it moves. That's why there's no upload-then-download wait, and why your file never sits on anyone's server.
On Android, transfers keep going in the background. On iPhone, keep Lahar on screen while it sends. For the really big ones, plug both phones in.
