Yuvachat connects your phone directly to others nearby over Bluetooth and Wi-Fi — building a mesh network that needs no internet, no cell signal, and no towers.
Yuvachat connects nearby phones directly to each other, forming a local mesh. Messages hop from phone to phone until they reach everyone in range — built for when normal networks are down, congested, or blocked.
Your phone talks straight to nearby phones over Bluetooth and Wi-Fi Direct — never touching the internet or cell towers.
Every phone running the app automatically discovers and connects to others nearby, extending the network's reach.
Messages don't need a direct connection — they hop phone to phone across the crowd until they reach everyone.
There's nothing to sign up for and nothing stored centrally. Each device is just its own identity on the mesh.
Yuvachat uses the same Bluetooth and Wi-Fi hardware that connects headphones or casts a screen, to build a temporary local network with everyone else nearby running the app.
On launch, your phone starts advertising and scanning for other Yuvachat phones over Bluetooth Low Energy.
When two phones find each other, they connect and, when in range, upgrade to Wi-Fi Direct for faster transfer.
A sent message passes to every connected phone, which passes it to theirs — hopping outward until it reaches everyone, up to 6 hops.
Each phone remembers messages it has already relayed, so nothing loops endlessly around the mesh.
No sign-up, no setup wizard — just install and open.
Download and install Yuvachat on your phone.
Allow Bluetooth and nearby-device access — that's what lets your phone find and talk to others directly.
Yuvachat starts finding nearby phones automatically — the header shows how many peers you're connected to.
Your message reaches everyone connected directly to you, and relays outward through the mesh to reach phones further away.
Your phone will warn about installing outside the Play Store — this is expected for a direct APK download. Allow the install to continue.
Each hop covers roughly the range of Bluetooth or Wi-Fi Direct — tens to a couple hundred meters depending on conditions. The mesh's real reach comes from how many phones are relaying: the more people nearby running the app, the further messages travel.
No. Yuvachat never touches cellular data or Wi-Fi internet — it only uses direct device-to-device radio connections.
Messages pass through relay phones to reach their destination, similar to how mesh networks generally work. Treat the mesh as a shared local channel rather than a private line.
Bluetooth scanning and relaying uses more power than an idle phone — similar to keeping Bluetooth audio connected continuously.
Yuvachat is free, open, and needs nothing but nearby phones to work.
