Saberra Translate is a free Android app that turns your phone into a two-way conversation translator. Press start and talk. Each side hears the other's words spoken aloud in their own language. Everything runs on the phone itself: no account, no cloud, no data leaving the device. It works in airplane mode, on a mountain, or in a basement market on the other side of the world.

Tap the finished download. Android asks permission to install apps from your browser. Allow it once. If Play Protect asks, choose Install anyway.
On Wi-Fi, the app downloads its offline speech models (~360 MB, one time). Grant the microphone permission, pick your languages, and start talking. After setup it works with no connection at all.

Speech recognition, translation, and the spoken voices all run on your phone. Nothing you say is recorded, stored, or sent anywhere. There is no server to send it to. The only network use is downloading language packs, which you control.
Requirements: Android 7.0 or newer, ~1.5 GB free storage with several languages installed. Phones from roughly 2018 onward handle it comfortably.
Saberra builds Sera, an AI operations layer that listens to the real work happening in meetings and email and turns it into institutional memory teams can trust. Saberra Translate started as an internal proof of the same engineering: modern speech AI running entirely on an ordinary phone. It turned out too useful to keep to ourselves.
So it is a gift. No account, no ads, no data collection, and nothing inside the app to upsell. If it helps you talk with someone you otherwise could not, it has done its job.
Our day job is helping organizations stop losing decisions, tasks, and context in the stream of meetings. If your team keeps asking what was decided, who owns it, and where that conversation went, that is the problem we work on.
