Android Lollipop introduced the Trusted Face feature, which allows you to unlock your tablet or smartphone using facial recognition. That said, it’s not as reliable as Apple Face ID and people can still gain access to your Android device if they know your password. As a result, third-party developers have been creating their own facial recognition apps for Android to take full advantage of this exciting technology.

Railer is an impressive tool that teachers will love. Instead of calling out the roll call every day, you can quickly take a class photo with your smartphone and Railer will keep track of attendance for you. Railer is also used in professional environments thanks to its analytics and leave management capabilities. The one-touch facial recognition feature is especially useful for learning the names of students and colleagues.

If you’re looking to delve deeper into the emerging field of facial recognition apps, Luxand is made for you. The open-source SDK includes multiple facial detection APIs for a variety of fun and practical purposes. You can even create augmented reality apps. The app itself lets you assign names to faces in photos, which Luxand will remember and recognize in the future. This can be useful for automatically tagging friends in photos or for surveillance purposes.

BioID is a cloud-based web security service, but anyone can download the free Face Recognition app. Like IObit, BioID can be set up to protect specific apps and websites. In addition to its enterprise services, BioID has a handy feature that allows developers to add facial recognition capabilities to their projects without any knowledge of how biometrics work. BioID also has smart “liveness detection” and challenge responses to prevent users from fooling the app with photos or videos of you.
