Downloads

One application, built for each platform it ships on. Pick yours, or open it in a browser with nothing to install.

Beta ZYRNTOPO is still in beta and under active development. Expect bugs, rough edges and the occasional error — including in map downloads and offline maps, which are the areas changing fastest right now. Do not rely on it as your only navigation tool in the backcountry. If something breaks, tell us what happened; reports from the field are what these releases are built from.

Coming: a native app. Everything below is the web build — the same application, packaged for each platform. A native ZYRNTOPO for Android, Windows and Linux is in development: not a web app in a shell, but a real client with its own map engine. No release date yet, and the builds here keep shipping and stay supported in the meantime.

Android

Android 7.0 or later, phone or tablet. Google Play installs and updates it for you; the signed APK is published too.

Get it onGoogle Play

Direct download (APK)

Universal build — all ABIs, for a device with no Play access

Sideload over adb

curl -fLO https://pois.zyrntopo.com/downloads/zyrntopo-1.15.25-beta.apk
adb install zyrntopo-1.15.25-beta.apk

Sideloaded copies do not update themselves.

Windows

Windows 10 or 11 — 64-bit, ARM64 or 32-bit. The same application in a desktop shell.

Download forWindows 64-bit

All Windows builds (6)

Take the 64-bit build unless you know otherwise. ARM64 is for a Snapdragon machine such as a Surface Pro 11. The .exe installs for the current user; the .msi is for Group Policy or Intune.

Verify before running

Get-FileHash zyrntopo-1.15.25-win-x64-setup.exe

The installers are not code-signed yet, so SmartScreen shows “Windows protected your PC.” Check the SHA-256 against the download archive, then choose More info → Run anyway.

Linux

Debian, Ubuntu, Fedora, RHEL, openSUSE and Arch get their native package; anything else gets a self-contained AppImage that needs no root.

One command, any distribution

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

Individual packages (8)

The installer detects your distribution and architecture, verifies the SHA-256 and installs the right file. No 32-bit build ships.

64-bit x86 — standard PCs and laptops

ARM64 — ARM laptops, Raspberry Pi 4/5 on a 64-bit OS, ARM servers

Then manage it with

zyrntopo update
zyrntopo version
zyrntopo remove

Amazon Fire

Fire HD and Fire Max tablets, and any Android device running the Amazon Appstore.

Available atAmazon Appstore

Which Fire tablets

Fire OS 6, 7 and 8. Fire OS 5 devices sit below the Android 7.0 floor and cannot run it. No Fire tablet carries a GPS receiver, so position comes from Wi-Fi rather than satellites.

Browser

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

Open the web app

What works in a browser

Every offline feature works once an area is saved. Needs a current browser with WebGL2; installing it to the home screen keeps it available offline.

Current release 1.15.25 (build 244) — Android 1.15.25, Windows 1.15.25, Linux 1.15.15. Sizes and SHA-256s for every file are listed in the download archive.

Fire tablets carry no GNSS receiver — position is derived from Wi-Fi. Fire OS 5 devices sit below the Android 7.0 floor.

What it needs

Version: 1.15.25 (build 244)
Graphics: WebGL2 for the map; 3D terrain needs it too.
Storage: Sized to your saved areas — gigabytes are normal.
Network: To save areas, buy Pro and sync. Not to navigate.
Permissions: Location in the foreground; continuous only while recording a track.
Account: Only for Pro and Team Sync. The free map works without one.
