Choose the download option shown for your device. If it opens an app store, follow the prompts there to install DC Metro and Bus.

Some download buttons link to Google Play, the App Store, or the developer's website. When you select one of those buttons, you complete the download on the page that opens.

If you see an App Store button, tap it to check availability for your device. If only Google Play is listed, that link is for Android. You can check the developer's website to see whether an iPhone or iPad version is available.

Check the price on the official store listing before downloading. Even when an app is free to install, some features may require a purchase or subscription.

Open the official store listing on the device you plan to use. Check the system requirements and any compatibility message shown for your device.

Check the Other Versions section for a link to the release you want. If you only see a store button, it opens the store listing and does not let you select a specific older version from this page.

Check your internet connection and available storage, then try again. If you see an error message, note what it says before retrying. You may need to free up space or update your device.

App availability can vary by country or region. Check the country or region associated with your store account and visit the developer's website for information about supported locations.

If you installed the app through Google Play or the App Store, open its listing and select Update if the option appears. If you installed it directly from the developer, follow the update instructions provided by the developer.

For sign-in, billing, or problems using the app, open its official store listing and look for the developer's support link or contact details. Include your device model and any error message when describing the problem.
