Hi

Yes, Odoo does have mobile apps that are beginner-friendly and easy to use. The official apps cover most common modules like CRM, Sales, Timesheets, and more, and are designed to work on both Android and iOS.

For a more flexible and full-access mobile experience, especially if you want all modules including custom ones, you can also use a WebView-based mobile app.
