Yes. OpenVPN Connect is a reliable and trustworthy app for using VPNs that don't have an in-house app. Simply install OpenVPN Connect on your device and then import TrueVPN server profiles one at a time or all at once. The downside is OpenVPN Connect doesn't have a kill switch or many other security features offered by in-house app. If you don't want to bother with downloading and importing several server profiles, try one of these top vendors that offer in-house apps for multiple devices.
