Get ZYRNTOPO on every device you carry.

One app for phones, tablets and the browser, plus a 3D desktop app. Every install command checks the download against its published SHA-256 before anything runs.

ZYRNTOPO

The field app, for every device.

The same app on a phone, a tablet and in the browser. Free to use, with Pro for teams.

Android

Available

Android 7.0 or later, phone or tablet. The store installs and updates it for you.

Get it on Google Play Get it on Amazon Appstore

Fire HD and Fire Max tablets on Fire OS 6, 7 and 8 install from the Amazon Appstore. Fire tablets have no GPS receiver, so position comes from Wi-Fi.

Web

Available

Nothing to install and no account. Any current browser with WebGL2 runs the full app, and it installs to the home screen or desktop.

Open in your browser

Every offline feature works once an area is saved. Installing it keeps it available with no connection.

ZYRN Workstation

The 3D desktop app.

Its own map engine with 3D terrain, a globe view and ZYRNTOPO's maps, offline. Its install commands use the short name zyrngis.

TAK server

Team Sync on hardware you own.

One command installs a single program as a service, with no Docker. It creates the certificates and a first user, opens the firewall and sends a test position through the server before it reports success.

A VPS, a Raspberry Pi or a spare laptop will do. ZYRNTOPO, ATAK, WinTAK and iTAK connect to the same server. Positions and messages never leave it.

What the installer sets up

Linux or macOS

curl -fsSL https://zyrntopo.com/tak-server.sh | sh

Windows, in PowerShell
