User Reviews

• “Great app. One suggestion: when we receive a communication, the app should pop up quickly so replies aren’t delayed—though it should be optional.”
• “This app is so good. It would be even better with more sound options—like alerts if the microphone is muted or if the connection changes—and an improved talk-permit tone.”
• “I love it for a few reasons: it behaves like a walkie talkie with effectively unlimited range, you can exit so you don’t receive messages (awesome when you’re off the clock), and it records everything—perfect for situations like ‘I didn’t say that.’”
• “Used Zello for four years as a backup channel for mountain rescue. When digital radio is out of range, Zello keeps us connected to base. Sound quality can be better than DMR, and it works anywhere your 3/4/5G network reaches. All calls are recorded and reviewable later.”

What is Pre-Buffering and how does it work?

On platforms that include the Jitter Adjustment Threshold setting, Pre-Buffering sets the default buffer size. This buffer is used initially until the algorithm has enough data to adjust the buffer size based on current network conditions.
