NEXT-GEN ARCHITECTURE

Features Engineered for
Pure Connection.

Most calling apps route your intimate calls through bloated cloud relay servers. QualityTime connects phones directly, delivering unrivaled speed, zero data storage, and studio-grade audio/video fidelity.

DIRECT CONNECTION

True Device-to-Device WebRTC

Your voice and video streams travel straight from your phone to the recipient's phone via encrypted WebRTC DTLS-SRTP tunnels.

Zero Server Storage: No middleman server records or stores your conversations.
Lowest Latency: Direct peer paths shave off 80–120ms of routing delay compared to centralized apps.
Intelligent NAT Traversal: Effortlessly establishes direct links through firewalls and mobile cell towers.

Native Lockscreen CallKit Ringing

Many VoIP apps fail to wake up in the background when Android's aggressive battery savers put them to sleep. QualityTime leverages high-priority FCM signaling and Flutter CallKit integration so your phone rings like a normal cellular phone call, even when locked.
