Yes, we have an agent Deskpro app for both iOS and Android.
Agents can view, manage and reply to tickets in real-time using the Deskpro apps, that link directly to your helpdesk. We don't believe that users will want to install an app just to get support. Users on mobile devices can submit tickets via email or by using the simple ticket submission form on the portal.
You can also embed our ticket submission form into a mobile-optimized website, so that your users can submit tickets when they are browsing on mobile.
