How do I install or uninstall apps on my Ledger device?

Managing Applications on Your Ledger Device

Interacting with blockchain applications through a Ledger hardware wallet requires installing and uninstalling apps directly onto the device. This process ensures secure access to cryptocurrencies and decentralized platforms while maintaining offline private key protection. Users must utilize Ledger Live, the official desktop and mobile interface, to manage these applications efficiently.

Installing Apps via Ledger Live

1. Connect your Ledger device to your computer using the provided USB cable and enter your PIN to unlock it.
2. Open Ledger Live and navigate to the 'Manager' section, which appears once the device is detected.
3. Browse the available apps or use the search bar to locate a specific cryptocurrency or dApp, such as Bitcoin, Ethereum, or Uniswap.
4. Click the install button next to the desired app; Ledger Live will display memory requirements and compatibility details.
5. Confirm the installation request on your Ledger device by pressing both buttons when prompted, ensuring no unauthorized installations occur.

Uninstalling Apps from Your Ledger

1. With your Ledger connected and unlocked, open Ledger Live and go to the 'Manager' tab.
2. Locate the installed app you wish to remove; each entry shows an uninstall option if the app is currently on the device.
3. Select the uninstall icon (trash bin) beside the app name, triggering a confirmation prompt in the software.
4. Verify the removal request on your Ledger screen by pressing both buttons simultaneously to approve the action.
5. Wait for Ledger Live to confirm the successful deletion, freeing up space for other applications.

Important Considerations During App Management

1. Ensure your Ledger firmware is updated before installing new apps, as outdated versions may block certain installations.
2. Be mindful of available storage—each app consumes a portion of the device’s memory, limiting how many can coexist.
3. Never install apps from unofficial sources or third-party tools, as this compromises security and exposes keys to potential theft.
4. Some blockchain networks require multiple related apps—for example, Ethereum tokens often depend on the base Ethereum app being present.
5. If an app fails to install or disappears after reboot, check for conflicts with other apps or insufficient memory allocation.

Frequently Asked Questions

Can I reinstall an app without losing my funds?Yes, reinstalling a cryptocurrency app does not affect your balance. Your assets are secured by your recovery phrase, not stored within the app itself.

Why can't I find a specific token in the Ledger Live catalog?Not all ERC-20 or BEP-20 tokens have dedicated Ledger apps. For unsupported tokens, use the Ethereum or Binance Smart Chain app with custom contract address configuration in compatible wallets.

What happens if I uninstall a wallet app by mistake?Uninstalling an app removes only the interface, not the associated crypto assets. You can safely reinstall the app later and regain access using your Ledger’s private keys.

Is there a limit to how many apps I can install at once?Yes, the number depends on your Ledger model's internal storage. Devices like the Ledger Nano X support more apps than the Nano S due to increased memory capacity.
