Get ZYRNTOPO on every device you carry.

Install from a store, with one command, or download the file and install it yourself. Every file has a published SHA-256, and the install commands check it 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

Download the APK

zyrntopo-1.18.16-android.apk

Open it on the phone or tablet and let your browser install apps when Android asks. It does not update itself, so get new versions from this page.

Android installs an APK only over a copy signed with the same key, and the Google Play copy is signed by Google. To switch, uninstall the store copy first. That deletes the offline maps saved on the device.

From a computer with USB debugging turned on:

adb install zyrntopo-1.18.16-android.apk

Checksum: SHA256SUMS-zyrntopo-1.18.16.txt

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.

iPhone and iPad

Web app

ZYRNTOPO runs in Safari and installs to the home screen like any other app. Open it in Safari, tap Share, then Add to Home Screen. A native iPhone and iPad app is planned.

Open the web app

iOS pauses web apps in the background, so keep the screen on while you record a track.

Web

Available

Nothing to install. Sign in with a free account the first time you open it. 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.

ZYRNMAPS

The native Android app.

ZYRNMAPS is ZYRNTOPO built as a native Android app. It draws the map on the GPU, keeps a steady frame rate on low-end hardware, starts quicker and takes native Android plugins.

It installs next to ZYRNTOPO, and your account and Pro work in both.

About ZYRNMAPS

ZYRNMAPS for Android

Available

Android 7.0 or later with Vulkan 1.0.3 or newer. If it will not install, or shows a black map, use ZYRNTOPO on that device.

Get it on Google Play Download the APK

Install the APK yourself

Open zyrnmaps-0.2.28-android.apk on the device and let your browser install apps when Android asks. It does not update itself, so get new versions from this page.

The Google Play copy is signed by Google, so Android will not install this APK over it. To switch, uninstall the store copy first.

adb install zyrnmaps-0.2.28-android.apk

Checksum: SHA256SUMS-zyrnmaps-0.2.28.txt

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.

About ZYRN Workstation

ZYRN Workstation for Windows

Available

Windows 10 or 11, 64-bit, with an OpenGL 4.1 graphics card. The command installs it for your Windows account. To install it for everyone on the PC, use the MSI.

irm https://zyrntopo.com/zyrngis.ps1 | iex

Installer (.exe) MSI for all users

Managed fleets and updates

$env:ZYRNGIS_METHOD='msi'; irm https://zyrntopo.com/zyrngis.ps1 | iex

The MSI installs for every user and needs an administrator. For Intune, Group Policy or a deployment script:

msiexec /i zyrngis-1.1.15-win-x64.msi /qn

The installers are not code signed yet, so Windows SmartScreen warns about a file downloaded in a browser. Check the file against the published checksum below before you open it. The PowerShell command does that check for you.

Then manage it with zyrngis update, zyrngis version and zyrngis remove. ARM64 PCs run the x64 build under emulation.

Checksums: SHA256SUMS-zyrngis-1.1.15.txt

ZYRN Workstation for Mac

Available

macOS 13.3 or newer. Intel Macs run it directly, Apple silicon Macs through Rosetta 2, which the installer adds if it is missing. Installs to Applications.

curl -fsSL https://zyrntopo.com/zyrngis.sh | sh

App (.tar.gz)

Install from the file

Double-click the file to unpack it, then drag ZYRN Workstation to Applications. The app is not notarized by Apple yet, so macOS will not open a copy downloaded in a browser. Check the file against the published checksum below, then run this once in Terminal:

xattr -dr com.apple.quarantine "/Applications/ZYRN Workstation.app"

Or download and unpack it in Terminal:

curl -fL https://zyrntopo.com/dl/zyrngis-1.1.15-macos-x86_64.tar.gz | tar -xz -C /Applications

On Apple silicon, install Rosetta 2 first if you have not:

softwareupdate --install-rosetta --agree-to-license

Manage it with zyrngis update, zyrngis version and zyrngis remove.

Checksums: SHA256SUMS-zyrngis-1.1.15.txt

ZYRN Workstation for Linux

Available

64-bit x86 with glibc 2.35 or newer and an OpenGL 4.1 driver. Installs to /opt/zyrngis with everything it needs.

curl -fsSL https://zyrntopo.com/zyrngis.sh | sh

.deb .rpm .pacman AppImage .tar.gz

Install a package from a terminal

Debian, Ubuntu and Mint:

curl -fLO https://zyrntopo.com/dl/zyrngis-1.1.15-linux-amd64.deb && sudo apt install ./zyrngis-1.1.15-linux-amd64.deb

Fedora, RHEL and openSUSE:

sudo dnf install https://zyrntopo.com/dl/zyrngis-1.1.15-linux-x86_64.rpm

Arch, Manjaro and CachyOS:

curl -fLO https://zyrntopo.com/dl/zyrngis-1.1.15-linux-x64.pacman && sudo pacman -U ./zyrngis-1.1.15-linux-x64.pacman

Any distribution, as one file in your home folder (AppImage):

curl -fLO https://zyrntopo.com/dl/zyrngis-1.1.15-linux-x86_64.AppImage && chmod +x zyrngis-1.1.15-linux-x86_64.AppImage && ./zyrngis-1.1.15-linux-x86_64.AppImage

Check a download against the published checksums:

curl -fLO https://zyrntopo.com/dl/SHA256SUMS-zyrngis-1.1.15.txt && sha256sum -c --ignore-missing SHA256SUMS-zyrngis-1.1.15.txt

Without a package manager

curl -fsSL https://zyrntopo.com/zyrngis.sh | ZYRNGIS_METHOD=appimage sh

Then manage it with zyrngis update, zyrngis version and zyrngis remove.

ZYRN Workstation on the Snap Store

Available

64-bit x86 Linux with snap, which Ubuntu has built in. The store installs and updates it for you.

Get it from the Snap Store

Install from a terminal

sudo snap install zyrngis

Remove it with sudo snap remove zyrngis.

It runs sandboxed, so it can't use USB GPS receivers, radios or your system's location service. For those, use the Linux command.

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, adds firewall rules for its own ports 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 stay on it unless you link it to another server.

What the installer sets up

Linux or macOS

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

Windows, in PowerShell

irm https://zyrntopo.com/tak-server.ps1 | iex

TAK server packages for Linux and Raspberry Pi

Installing a package sets the server up the same way the command above does and prints the dashboard address and the administrator password. Removing it takes the service and the firewall rules away and keeps your data in /var/lib/zyrn-tak.

Install a package from a terminal

Any distribution, from the archive:

Checksums: SHA256SUMS-zyrn-tak-3.0.11.txt

TAK server for Windows

The MSI installs the Windows service, adds Windows Firewall rules for the server's ports and creates the administrator account. The password is in C:\ProgramData\ZYRN TAK\admin-password.txt.

MSI for x64 MSI for ARM64

Options and the program on its own

Setup options go in SETUPARGS, in a terminal run as administrator:

msiexec /i zyrn-tak-3.0.11-windows-x64.msi SETUPARGS=--host=tak.example.com

The program on its own, to run zyrn-tak setup yourself: zyrn-tak-windows-amd64.exe or zyrn-tak-windows-arm64.exe.

Checksums: SHA256SUMS-zyrn-tak-3.0.11.txt for the MSI files, SHA256SUMS-zyrn-tak.txt for the programs.

TAK server for Mac

macOS on Apple silicon or Intel. Unpack it and run setup, which installs a launchd service and allows the server through the macOS firewall.

Apple silicon Intel

Install from a terminal

curl -fL https://zyrntopo.com/dl/zyrn-tak-3.0.11-macos-arm64.tar.gz | tar -xz && sudo ./zyrn-tak-3.0.11-macos-arm64/zyrn-tak setup

On an Intel Mac, use the amd64 file. The program is not notarized by Apple yet, so a copy downloaded in a browser needs this first, in its folder, after you check it against the checksum:

xattr -d com.apple.quarantine zyrn-tak
