Crystal-clear voice calls, anywhere they walk.

Why teams switch
The hard parts of calling, already solved.
✕The problem
Robotic, choppy audio on bad networks
Packet loss on mobile data turns a voice into noise.
AppLooma
Built for weak networks
Opus with forward error correction and adaptive bitrate, and automatic reconnect after a network change.
✕The problem
Echo, wind and traffic noise
Speakerphone echo and street noise make people hang up.
AppLooma
Noise suppression and echo cancelling
Echo cancellation, noise suppression and automatic gain are on by default; switch noise suppression at runtime.
✕The problem
Wrong speaker, lost earbuds
Calls that start on the loudspeaker, or ignore the Bluetooth headset.
AppLooma
Audio routing that just works
Calls start on the earpiece; wired and Bluetooth headsets are picked up, with an in-call route API on Android and iOS.
✕The problem
Months spent building call UI
Avatars, timers, mute and speaker states for every screen size.
AppLooma
A ready-made call screen
The UIKit Call component in voice mode: pulsing avatar, timer, mute and end, in a few lines.
✕The problem
Ringing a user who is not in the app
An incoming call is useless if nobody sees it.
AppLooma
Works with your push
Send the invite through your own FCM or APNs push, show your incoming-call screen, and join the room on accept.
✕The problem
Users far from your server
Extra delay makes people talk over each other.
AppLooma
Smart routing
joinChannel connects each device to the nearest AppLooma media server automatically.

Easy to integrate
From zero to a working call screen in a day.
Launch in a day with the UIKit
The Call component for React, React Native, Flutter or Android Compose gives you a complete voice call screen.
UI and call logic included
Joining, muting, routing audio, reconnecting and leaving are handled for you. Use the core SDK when you want full control.
Your brand, your colours
Style the screens to match your app, or build your own UI on the same engine events.
val engine = AppEngine.create(applicationContext, "YOUR_APP_ID", handler)// audio-only: camera stays offengine.joinChannelAsync(token, wsUrl,AppJoinOptions(role = AppRole.HOST,microphone = true, camera = false))
Features
Everything a voice app needs.
1:1 voice calls
Phone-call voice tuned for speech, starting on the earpiece like a normal call.
Group voice
Many voices in one room with real-time speaking indicators for every person.

FAQ
Common questions.
Will calls work on a bad network?+
Yes. Opus forward error correction and adaptive bitrate keep voice intelligible on congested Wi-Fi and mobile data, and the SDK reconnects on its own after a network change.
Does it use the earpiece or the speaker?+
A call starts on the earpiece like a normal phone call. Wired and Bluetooth headsets are picked up automatically, and Android and iOS have an in-call route API for a speaker button.
Can I switch a voice call to video mid-call?+
Yes. Turn the camera on during the session; there is no need to rejoin.
How do incoming calls work when the app is closed?+
Send the call invite through your own push (FCM on Android, APNs on iOS) with the room name. When the user accepts, your app gets a token from your server and joins the room.
How is voice billed?+
By participant minute: two people talking for 30 minutes use 60 minutes. Voice and video are billed the same. Start with 3,000 Sandbox minutes, then a fixed monthly plan with no overage charges.
