Stagetimer Desktop App

What is the Desktop App?

Stagetimer’s desktop app is designed for environments where internet connectivity is unavailable or unreliable, such as remote event locations, conference centers with restricted network access, or corporate environments with regulated internet use. Additionally, using the desktop app can prevent disruptions caused by unexpected internet outages.

This version is available as an installable application for both Mac and Windows. It mirrors the capabilities of the web version, allowing a seamless transition between online and offline modes. The basic features of the offline app are free to download. Each Stagetimer plan includes an offline license key that activates the corresponding paid features in the desktop app.

Downloading the Desktop App

Download the latest version of the offline application from our official page:
https://stagetimer.io/desktop-app/

After downloading, run the installation file and follow the on-screen instructions. The setup process is straightforward, designed to get the app up and running with minimal hassle.

Installing the Desktop App

Windows

Download the Windows installer (.exe file) from the desktop app page.
Run the downloaded installer file. You’ll see it appear in your Downloads folder.

When you first run the installer, Windows may display a security warning. This appears because the app isn’t code-signed with an official Microsoft certificate, which can be challenging and costly for smaller developers like us.

Click “More info” on the first warning screen, then click “Run anyway” on the second screen. This is safe when the installer was downloaded directly from our official website.
The installer runs automatically and typically opens the Stagetimer app within a few seconds of clicking the setup file.

When you first launch the app, macOS may display a security warning because the app isn’t code-signed with an official Apple Developer certificate.

Click “Open” to proceed. This is safe when the app was downloaded directly from our official website. The security warning won’t appear on subsequent launches.

💡 If the “Open” button isn’t available: Right-click on the Stagetimer app in your Applications folder and select “Open” from the context menu. This will bypass the security restriction and allow you to launch the app.

💡 Updates: Install updates by downloading the new .dmg file and repeating the drag-to-Applications process. Your existing data, rooms, and license keys will be preserved.

Ubuntu/Debian Linux

Download the appropriate Linux installer (.deb file) from the desktop app page. Choose between x64 (for standard Intel/AMD processors) or arm64 (for ARM-based systems like Raspberry Pi).
Install the package using one of these methods:

GUI Installation (Raspberry Pi and some desktop environments): Right-click on the downloaded .deb file and select “Package Install” from the context menu.

Command Line Installation: Open a terminal and navigate to your Downloads folder, then run:

sudo dpkg -i stagetimer.io-2.18.0-arm64.deb

Replace the filename with the exact name of your downloaded file.

Launch the application by running the stagetimerio command in a terminal:

The Stagetimer desktop app will open, showing the main interface:

💡 Alternative Launch Methods: Some desktop environments will also add Stagetimer to your application menu or launcher after installation, allowing you to start it without using the terminal.

💡 Updates: Install updates by downloading the new .deb file and repeating the installation process. Your existing data, rooms, and license keys will be preserved.

Starting the Stagetimer App for the First Time

The Stagetimer desktop app operates fully without an internet connection, using your local area network (LAN) to connect devices within the same network to your Stagetimer rooms.

If you have a paid Stagetimer plan, you’ll find an desktop app license key in the dashboard of the web interface. This key enables the premium features available online in your offline application.

For those unfamiliar with networking terms like IP addresses, refer to our “Working with Local Network” section below, which guides you through connecting devices on your local network.

Since the offline app operates independently of the internet, it does not maintain a connection with our servers. To transfer setups or room configurations from the web version to the desktop app, see the “Exchanging Data Between Web Version and Desktop App” section.

Working with Local Networks

The Stagetimer app leverages your local network to enable connectivity between devices within the same space. Follow this guide to set up your devices on a common network.

Preparations

The app needs to be running on only one computer within the network.
All devices should be connected to the same local network, typically achieved by connecting to the same WiFi router.
In environments like corporate or university networks with additional security protections, consult with the network administrator for assistance.

Step 1: Select the Network Interface

Open the Stagetimer offline app.
Navigate to the network settings and select the network interface connected to your router, often an IP address like 192.168.178.xx.
Click “Apply” to restart the server. Ensure the green “Status” URL updates to reflect the new IP address.

Note: Avoid using the default IP 127.0.0.1, as it is only accessible from the hosting computer.

Step 1b: Allow Network Access (Windows Only)

After updating the network settings, Windows may prompt you to allow network access for the app. Ensure both public and private network access are permitted to avoid connectivity issues.

Step 2: Verify Device Connection

Ensure that all devices, such as a Windows computer and an Android phone, are connected to the same router:

Verify that the SSID (router name) is the same on all devices.
The IP addresses should be similar, typically matching all segments except for the last.

Step 3: Open and Verify Room URL

Open a room within the Stagetimer app.
Ensure the URL displayed in the address bar and the URL in the shareable links popup match the IP address selected in Step 1.

Step 4: Access from Another Device

Open the link or scan the QR code provided in Step 3 on your other device (e.g., a mobile phone) to join the room.

Note: Connection issues in settings with stringent security protocols, like universities or office buildings, may require consultation with your system administrator.

Exchanging Data Between Web and Desktop App

As of version 2.13, Stagetimer supports data synchronization between its web and offline applications. You can export your room data as a JSON file from the web version and import it into the offline app, and vice versa. This process captures all settings, timers, and messages associated with the room.

It is important to note that background images are not included in the JSON export. These images are typically linked to our servers. If you are using the desktop app in a setting without internet access, you may need to manually re-upload any background images used in your rooms.

Exporting from Web Version

Navigate to the room you wish to export.
Select the “Export” option, found in the room settings menu.
Save the generated JSON file to your device.

Importing to Desktop App

Open the Stagetimer offline app.
Go to the room where you want to import the data.
Choose the “Import” option and select the JSON file you exported from the web version.
Upload any necessary background images separately, if applicable.

Transferring License Keys Between Machines

License keys for the Stagetimer desktop app can be moved between different computers and operating systems. This is useful when upgrading to a new machine or switching between Windows, macOS, and Linux installations.

Removing a License Key

Open the Stagetimer desktop app on the machine you want to remove the license from.
Click “Enter License Key” in the License section.
In the license window, click the “Remove Key” button.

The app will return to the free/starter version on this machine.

Using the Key on Another Machine

Once removed, you can enter the same license key on any other Stagetimer desktop app installation. License keys work across all supported operating systems (Windows, macOS, and Linux) as long as the key is still valid and hasn’t expired.

Important: Each license key can only be active on one machine at a time. You must remove it from the current machine before using it elsewhere.

Troubleshooting

Site Can’t Be Reached

If you’re seeing error messages like “This site can’t be reached” or “Unable to connect” when trying to access Stagetimer from phones, tablets, or other devices on your network, the issue is likely related to the network interface setting.

Check the URL: Look at your browser’s address bar. If you see an address starting with 127.0.0.1 (like http://127.0.0.1:3000), this is the problem. The address 127.0.0.1 is a special “localhost” address that only works on the computer running the app—other devices on your network can’t reach it.

The Solution: You need to change the network interface in the Stagetimer app settings to use your computer’s actual network IP address instead of the default localhost setting. This makes the app accessible to other devices on your local network.

How to Fix It: Follow the detailed instructions in the Working with Local Networks section above. You’ll need to select your computer’s network interface (typically an IP address like 192.168.1.xxx) and restart the server.

Network Limitations: Keep in mind that the desktop app only works within your local network (devices connected to the same WiFi router). Devices outside your local network cannot access the app unless you have advanced networking setups like VPN tunnels or port forwarding configured.
