Everything that matters
Rich features. Simple to use.
We are designing practical communication features first, with security and call reliability as release priorities.
Internet voice calling
Low-latency WebRTC voice with a direct path when possible and TURN relay fallback when enabled.
Privacy by design
Private contacts, block controls, permission-based access and account deletion. Reporting tools are planned.
Incoming-call alerts
Incoming-call screen while the web app is open; browser push and native Android ringing are future work.
Nine languages
Choose among English, Bangla, Japanese, Chinese, French, German, Spanish, Arabic and Russian for the main navigation and core controls. Long-form information pages remain primarily English.
Lightweight experience
Fast interface, data-conscious operation and clear call reconnection status.
Try before launch
Experience the layout, not just a picture.
Click through chats, contacts and a simulated voice-call screen. The separate visual demo remains simulated. The real V4 app is linked above and requires Google login.

A successful real two-person call
Two registered accounts have completed a live voice conversation. We will not claim worldwide call reliability or video compatibility until testing across devices and networks.
Cloudflare Workers + D1 + Durable Objects + WebRTC are implemented for pilot testing, subject to free-tier capacity and relay billing safeguards.
Built in Bangladesh. Designed to connect the world.
