Zello is implementing important updates to enhance the reliability, security, and performance of our services. As part of these improvements, we are discontinuing support for older versions of the Zello apps. These older versions will stop working and must be updated to continue using Zello.

Deprecated Zello Versions

Effective 25 June 2025 Zello is deprecating older Zello app versions:

• Android app versions older than 6.0.2 (Note: newer versions no longer support Android OS versions earlier than 7)
• iOS app versions older than 6.1 (Note: newer versions no longer support iOS versions earlier than 14)
• Legacy PC app – all versions

To continue using Zello, update your Zello app to a supported version.
